Introduction
MultiROM is one-of-a-kind multi-boot mod for Nexus 7. It can boot any Android ROM as well as other systems like Ubuntu Touch, Plasma Active, Bohdi Linux or WebOS port.Besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs, daily prebuilt image files to install Ubuntu Touch and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Use for example Ubuntu Touch or Desktop alongside with Android, without the need of device formatting
* Boot from USB drive attached via OTG cable
You can also watch a video which shows it in action.
Warning!
It _is_ dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is messing with boot sector and data partition. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.
Installation
1. Via MultiROM Manager app
This is the easiest way to install everything MultiROM needs. Install the app and select MultiROM and recovery on the Install/Update card. If the Status card says Kernel: doesn't have kexec-hardboot patch! in red letters, you have to install also patched kernel - either select one on the Install/Update card or get some 3rd-party kernel here on XDA. You are chosing kernel for your primary ROM, not any of your (future) secondary ROMs, so select the version accordingly.
Press "Install" on the Install/Update card to start the installation.
2. Manual installation
Firstly, there are videos on youtube. If you want, just search for "MultiROM installation" on youtube and watch those, big thanks to all who made them. There is also an awesome article on Linux Journal.
Note 1: There have been reports that (not only) MultiROM does not work properly with older bootloaders. Update it to version 4.13 or newer in case you have problems.
MultiROM has 3 parts you need to install:
MultiROM (multirom_vXX_n7-signed.zip) - download the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_multirom_n7_YYYYMMDD.img) - download the IMG file from second post and use fastboot or Flashify app to flash it.
Patched kernel - You can use either one of the stock ones in second post or third-party kernels which include the patch, you can see list in the second post. Download the ZIP file and flash it in recovery.
You current rom will not be erased by the installation.
Download links are in the second post.
Adding ROMs
1. Android
Go to recovery, select Advanced -> MultiROM -> Add ROM. Select the ROM's zip file and confirm. As for the space, clean installation of stock 4.2 after first boot (with dalvik cache generated and connected to google account) takes 676mb of space.
2. Ubuntu Touch
Use the MultiROM Manager app to install Ubuntu Touch.
Ubuntu Touch is in development - MultiROM will have to be updated to keep up with future changes in Ubuntu, so there's a good chance this method stops working after a while and I'll have to fix it.
3. Ubuntu Desktop
Ubuntu desktop for Nexus 7 has been discontinued and is no longer updated. 13.04 is the last release.
Download Ubuntu 13.04 image from here. Put the image in the memory of N7 or to USB flash drive and go to recovery. Select Advanced -> MultiROM -> Add ROM and choose "Ubuntu" as ROM type. Then select the Ubuntu's image and confirm. Clean installation of Ubuntu is 1.5gb big, and takes a while (10 minutes?) to install.
The first boot takes a bit longer, and 13.04 stays a while (30-60s) in console ("Enter login:") before the GUI shows up, so just wait a while.
Ubuntu ROM must not have spaces in name!
Using Ubuntu on N7, Frequently Asked Questions
Using USB drive
During installation, recovery lets you select install location. Plug in the USB drive, wait a while and press "refresh" so that it shows partitions on the USB drive. You just select the location (extX, NTFS and FAT32 partitions are supported) and proceed with the installation.
If you wanna use other than default FAT32 partition, just format it in PC. If you don't know how/don't know where to find out how, you probably should not try installing MultiROM.
If you are installing to NTFS or FAT32 partition, recovery asks you to set image size for all the partitions - this cannot be easilly changed afterward, so choose carefully. FAT32 is limited to maximum of 4095MB per image - it is limitation of the filesystem, I can do nothing about that.
Installation to USB drives takes a bit longer, because the flash drive is (usually) slower and it needs to create the images, so installation of Ubuntu to 4Gb image on my pretty fast USB drive takes about 20 minutes.
Enumerating USB drive can take a while in MultiROM menu, so when you press the "USB" button in MultiROM, wait a while (max. 30-45s) until it searches the USB drive. It does it by itself, no need to press something, just wait.
Updating/changing ROMs
1. Primary ROM (Internal)
Flash ROM's ZIP file as usual, do factory reset if needed (it won't erase secondary ROMs)
Go to Advanced -> MultiROM in recovery and do Inject curr. boot sector.
2. Secondary Android ROMs
If you want to change the ROM, delete it and add new one. To update ROM, follow these steps:
Go to Advanced -> MultiROM -> List ROMs and select the ROM you want to update.
Select "Flash ZIP" and flash ROM's ZIP file.
In some cases, you might need to flash patched kernel - get coresponding patched kernel version from second post and flash it to the secondary ROM sama way you flashed ROM's ZIP file.
Explanation of recovery menus
Main menu
- Add ROM - add ROM to boot
- List ROMs - list installed ROMs and manage them
- Inject boot.img file - When you download for example kernel, which is distrubuted as whole boot.img (eg. franco kernel), you have to use this option on it, otherwise you would lose MultiROM.
- Inject curr. boot sector - Use this option if MultiROM does not show up on boot, for example after kernel installation.
- Settings - well, settings.
Manage ROM
- Rename, delete - I believe these are obvious
- Flash ZIP (only Android ROMs) - flash ZIP to the ROM, for example gapps
- Add/replace boot.img - replaces boot.img used by this ROM, this is more like developer option.
- Re-patch init - this is available only for ubuntu. Use it when ubuntu cannot find root partition, ie. after apt-get upgrade which changed the init script.

3. Linux ROMs (Bohdi, Plasma Active, WebOS packed for MultiROM)
You can find these systems in separate thread: forum.xda-developers.com/showthread.php?t=2093797
4. Uninstaller
MultiROM uninstaller: multirom_uninstaller-2.zip
Flash this ZIP file to remove MultiROM from your device. It will erase all secondary ROMs. If you don't want MultiROM menus in recovery, re-flash clean TWRP, but it is not needed - those menus don't do anything if MultiROM is not installed.
5. Flashable factory images ZIPs
I usually release flashable ZIP files based on new factory images from Google, so that you can have clean stock ROM as a secondary system in MultiROM. They are not rooted, no anything, except for occasional small tweaks to make rooting with SuperSU possible. You can find them in this folder on basketbuild or dev-host.

* Add support for LZ4 & LZMA ramdisk compression
* Add some handy buttons to "flash complete" page,
thanks ikslawlok for suggestion
2.3.2013
=====================
* Fix freeze when selecting ROM in "Add ROM" option
in MultiROM menu
1.3.2013
=====================
* Updated to TWRP 2.4.3.0
27.2.2013
=====================
* Fix recovery kernel, so that you can boot linux ROMs even if
kernel in internal memory has older kexec-hardboot patch
* Enable brightness settings from TWRP
26.2.2013
=====================
* Updated to TWRP 2.4.2.0

22.2.2013
=====================
* Fix Ubuntu Touch installation with
combination of 4.2 as Internal ROM
21.2.2013
=====================
* Don't copy the ZIP to RAM while flashing ZIPs bigger
than 450 MB (currently only Ubuntu touch) in "Add ROM"
or "Flash ZIP" options. This prevents crash which would appear
due to low memory, but also means that these ZIP files
will be modified, which makes them unusable outside MultiROM
after flashing.
* Add Ubuntu touch support
2.2.2013
=====================
* Update to TWRP 2.4.1.0
* Don't reset ROMs location in "List ROMs" when going back
from managing ROM to the ROM list

in /data, thanks rifraf for debugging this
30.1.2013
=====================
* Update to TWRP 2.4.0.0
* Properly disable flash-kernel during Ubuntu installation.
This is important fix, because without it, Ubuntu
can rewrite your boot.img.
* Add option to wipe /data, /cache and dalvik-cache
of secondary Android ROMs
* Use gnutar binary compiled specifically for tegra 3,
means faster installation of Ubuntu
* Add "pressed" effect to all buttons, so that you know
if you pressed it or not.
* When installing Android ROM from ZIP which does not have
boot.img (armoma installer...), try to use current boot sector
instead of boot.img. The ROM may not boot, so you should always
add boot.img which is compatible to the ZIP file.
* Update to keep up with MultiROM v7

FAQ and other notes
Device encryption
Since v32, MultiROM supports encryption on this device (it has to be added for each device separately). It works only with Android-based secondary ROMs and the secondary ROMs don't know the device is encrypted, so they would allow you to encrypt the device again - do not do that. If you're using password, pin or pattern for the encryption, MultiROM will ask you for the password on boot. If you're booting the primary ROM, then Android will ask you for the password _again_ - unfortunately, there is no way for me to pass the "unencrypted" status to Android. If you're booting secondary ROM, MultiROM will ask you for the password again after the reboot - that's because I have to unencrypt the /data partition after the ROM's kernel is loaded.
I could omit the second password prompt when booting secondary ROM by temporarily saving the password somewhere, but that's obviously unsafe. So is using encryption with unlocked device though, so I might add this later.
About security
In order to make multi-booting possible, MultiROM has to sacrifice some security measures. Firstly, on secondary Android ROMs, /system is not mounted read-only. While there are other things preventing malicious software from messing with /system, this might potentialy make it easier for such software to attack that system.
What do the ROMs share?
All ROMs are separate, except /sdcard, which is shared between all Android ROMs.
How many ROMs can I have?/Where are the ROMs stored?
You can have as many ROMs as you can fit in your /sdcard. All the ROMs are stored in /sdcard/multirom/roms or on an USB drive. This folder is unaccessible in Android, to prevent mediascanner from scanning it. You can either in recovery, or obtain root and go to /data/media/0/multirom/roms.
Can I have different versions of Android working alongside
Yes. As long as you select "Don't shere kernel" when installing the secondary ROM, the systems are separated.
MultiROM recovery says it's 2.6.3.0. Why isn't it updated to 2.6.3.*highernumber*?
It is, it just shows wrong version.
The menu with all the ROMs won't show up during boot, how to fix it?
Either re-flash the MultiROM zip or go to recovery, Advanced -> MultiROM -> Inject curr. boot sector.
The reason for this is that something rewrote your boot.img, which happens for example when you flash a kernel. MultiROM's boot menu is part of the boot image, so it has to be added into it again.
Will you port MultiROM to device X?
No, probably. I won't port MultiROM to any device I don't own, because it is very difficult to provide the level of support I want to provide if I can't test things myself, as proven by the Nexus 4 port. I'd like to support more devices, but it is also very unsatisfying to work on code for device I don't have - I invest hours upon hours of time for free into it, and then I can't even see it running on the device, so...why..bother..?
I'll probably keep buying Nexus devices and keep porting MultiROM to those myself, but I can't buy every single device - I'm still a student, all my existing devices were bought using some kind of money grant or donations from users.
But, you can port it yourself, the wiki should give you at least some idea how to do that: https://github.com/Tasssadar/multirom/wiki/Porting-MultiROM

I will certainly be trying this out later. Thanks, will report back with my experience.

Absolutely amazing. Definitely going to give this a shot. Awesome work.

This is fantastic, works a treat here dual booting with latest PA/Trinity. Thanks very much for your work on this Tasssadar :highfive:

Time to do evil things... >

How much space is given to ubuntu on a 16gb nexus and what is left for android? can these be adjusted?

Clean installation of ubuntu takes about 1.5gb, but you need at least 2-3gb of free space for the installation process.
All data are saved to /sdcard/multirom folder. It is not separated in any way from your normal data - it eats up from the same storage as for example your movies and music.

I installed Multirom successfully, and used the boot screen and everything. I installed the ubuntu rootfs.img and it seems to be taking a long time on "Preparing the root file system, please wait, this will take a few minutes..." I had just under 2 GB free when I installed it, is that enough, used the Nexus 7 16 GB image.
EDIT: I just saw the post above, where are you getting you need 2-3 GB to install? I think Im going on 10 minutes...I may reboot to Internal(Android 4.2 AOKP) to free some storage space, delete a game or something, and start over installing Ubuntu.
EDIT 2: You a long list of No space left on device messages for a list of files, gotta start over.

It takes a while to install ubuntu, it extracts about 600mb archive, that means you need the space for archive itself and the extracted data (archive is erased at the end of the process). I say 3gb of free space just to be sure.
If it fails because it does not have enough space (you will notice the spam of "no space left" messages), just reboot to your internal ROM, then reboot to recovery, delete the ROM and try again with more free space.

My understanding of Ubuntu is that it can run microsoft office through the use of a virtual machine, does this support the use of a virtual machine?

My friend, you rules!, you´re the boss!, the big cheese, Big Kahuna!, etc, etc, etc.
Since I heard about Ubuntu for N7, I've been looking for a solution like that for I have both distro in my tablet. Now, thank to you, that is possible!.
Thank you for sharing, keep walking!!.
Cheers!,
P.S.: Btw, works terrific with my 4.2 rooted stock ROM in my 8GB N7

Stupid question...I clicked on the Ubuntu link and tried to download the 8gb Nexus image but it doesn't download. It opens it up. No download. Am I doing something wrong?

I got it working with AOKP 4.2 and Ubuntu, and I'm going to add PA Beta 3 once it gets re-uploaded. 2 android ROMs and Ubuntu! Awesome!

Introduction
MultiROM is one-of-a-kind multi-boot mod for Nexus 7. It can boot any Android ROM as well as other systems like Ubuntu Touch, once they are ported to that device. Besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from USB drive attached via OTG cable
You can also watch a video which shows it in action.
Warning!
It _is_ dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.
Installation
1. Via MultiROM Manager app
This is the easiest way to install everything MultiROM needs. Install the app and select MultiROM and recovery on the Install/Update card. If the Status card says Kernel: doesn't have kexec-hardboot patch! in red letters, you have to install also patched kernel - either select one on the Install/Update card or get some 3rd-party kernel here on XDA. You are chosing kernel for your primary ROM, not any of your (future) secondary ROMs, so select the version accordingly.
Press "Install" on the Install/Update card to start the installation.
2.Manual installation
Firstly, there are videos on youtube. If you want, just search for "MultiROM installation" on youtube and watch those, big thanks to all who made them. There is also an awesome article on Linux Journal.
MultiROM has 3 parts you need to install:
MultiROM (multirom-YYYYMMDD-vXX-flo.zip) - download the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_multirom_flo_YYYYMMDD.img) - download the IMG file from second post and use fastboot or Flashify app to flash it.
Patched kernel - You can use either one of the stock ones in second post or third-party kernels which include the patch, you can see list in the second post. Download the ZIP file and flash it in recovery.
You current rom will not be erased by the installation.
Download links are in the second post.
MultiROM is compatible with both flo and deb.
Adding ROMs
1. Android
Go to recovery, select Advanced -> MultiROM -> Add ROM. Select the ROM's zip file and confirm. As for the space, clean installation of stock 4.2 after first boot (with dalvik cache generated and connected to google account) takes 676mb of space.
2. FirefoxOS
Download FirefoxOS ZIP package from this thread. The installation is completely the same as Android ROMs.
3. Ubuntu Touch
Use the MultiROM Manager app to install Ubuntu Touch.
Ubuntu Touch is in development - MultiROM will have to be updated to keep up with future changes in Ubuntu, so there's a good chance this method stops working after a while and I'll have to fix it.
Using USB drive
During installation, recovery lets you select install location. Plug in the USB drive, wait a while and press "refresh" so that it shows partitions on the USB drive. You just select the location (extX, NTFS and FAT32 partitions are supported) and proceed with the installation.
If you wanna use other than default FAT32 partition, just format it in PC. If you don't know how/don't know where to find out how, you probably should not try installing MultiROM.
If you are installing to NTFS or FAT32 partition, recovery asks you to set image size for all the partitions - this cannot be easilly changed afterward, so choose carefully. FAT32 is limited to maximum of 4095MB per image - it is limitation of the filesystem, I can do nothing about that.
Installation to USB drives takes a bit longer, because the flash drive is (usually) slower and it needs to create the images, so installation of Ubuntu to 4Gb image on my pretty fast USB drive takes about 20 minutes.
Enumerating USB drive can take a while in MultiROM menu, so when you press the "USB" button in MultiROM, wait a while (max. 30-45s) until it searches the USB drive. It does it by itself, no need to press something, just wait.
Updating/changing ROMs
1. Primary ROM (Internal)
Flash ROM's ZIP file as usual, do factory reset if needed (it won't erase secondary ROMs)
Go to Advanced -> MultiROM in recovery and do Inject curr. boot sector.
2. Secondary Android ROMs
If you want to change the ROM, delete it and add new one. To update ROM, follow these steps:
Go to Advanced -> MultiROM -> List ROMs and select the ROM you want to update.
Select "Flash ZIP" and flash ROM's ZIP file.

Crowdfunding campaign
A crowdfunding campaign to get test devices took place from July 28th to August 27th 2013. Thanks all contributors, the campaign was successful, raising a total of $562. This enabled a purchase of flo and resulted in MultiROM being ported to said device and the code became much more portable.
These people pledged $10 or more and got perk "The Thread" or "The Code":

3. Uninstaller
MultiROM uninstaller: multirom_uninstaller-flo-2.zip
Flash this ZIP file to remove MultiROM from your device. It will erase all secondary ROMs. If you don't want MultiROM menus in recovery, re-flash clean TWRP, but it is not needed - those menus don't do anything if MultiROM is not installed.
4. Flashable factory images ZIPs
I usually release flashable ZIP files based on new factory images from Google, so that you can have clean stock ROM as a secondary system in MultiROM. They are not rooted, no anything, except for occasional small tweaks to make rooting with SuperSU possible. You can find them in this folder on basketbuild or dev-host.

Awesome work Tassadar!
I'm going to check it out right away
edit:
Got it up and running, no problems, thanks for the extra help

This is awesome ! With Ubuntu Touch coming in october, there'll be a party on my N7
A question though, why do we have to use a patched kernel, doesn't the kernel runs AFTER the multirom part ? I'm asking mainly because I fear for the upcoming Ubuntu Touch and maybe his brand-new kernel. If it's not compatible or will have to be patched, isn't there a risk that we have to "always" use a custom-kernel after every little update? (and Canonical knows his way in kernel updating every 2 weeks on desktop computer, especially with a new product...)
But I'm also asking to satisfy my curiosity ^^
Thank you very much, anyway, I'm glad your funding campain was a success. I can't hit the "Thanks" button enough.

MultiROM starts immediately _after_ kernel. When you select secondary ROM with different kernel, it needs to load it, somehow - that's what kexec is for. Only the kernel for primary ROM has to be patched though, so if you'd install Ubuntu Touch as secondary, it can live with it's own, unpatched kernel.
By the way, as far as I know, Canonical does not plan to support flo. Ubuntu Touch is planned to release in October, but that means it's going to get "stable" version for those 4 nexus devices (mako, manta, grouper and maguro) and possibly some new devices, which will be running Ubuntu Touch out of the box. I think flo needs a community port.

@Tasssadar
Looks awesome! I can't wait to give it a try! Hopefully Flar will inegrate the patch into her Kernel. Thanks a lot for the port!

Are the roms able to share apps/data like Modaco switch or is each rom independent?

In addition to this, what about files like docs, pics, etc? How is space alloted per rom? Is it adjustable after install?
Never tried this with my original N7 but I think I'll be trying it on the new one.

Abount the kernel, should i flash both modified kernels if i want to set a stock rom for the primary and cm10 for the sec?

Dear @Tasssadar.
Thanks for your efforts to the community. As you know, ElementalX kernel supports other roms rather than only stock. So my question is: can we run the first stock rom with patched kernel and second roms with ElementalX (roms don't share kernels)?

That is exactly how I am running it and all works fine.
Tasssadar - It looks as if it is running fine, I missed this so much when I moved over to DEB and now it is here woohoo!
I have noticed one thing though whenever I flash from my external flash drive it unmounts the usb-otg device after each flash. Have to go in and mount it back between rom, gapps and kernel flashes.

Go to Advanced -> MultiRom, select your rom and you will see flash option there.

I saw Bodhi Linux and Ubuntu in the screenshot, how do we install them? Does it accept .ISO and boot as Live CD? How is the hardware detection such as touch screen, etc, all recognized and working? Thanks.

/sdcard is shared between ROMs, so pictures, movies and such on there are shared. The space isn't really allocated - all roms are stored in /sdcard/multirom/roms (not accessible from Android, if you want to look in there, go to recovery). That means it eats up from the free space you can see in Settings -> Storage in Android.

No, only the aosp one for primary ROM. Secondary ROMs don't require patched kernel (which is actually an improvement over grouper's version).

Those screenshots are from old N7, because the GUI looks exactly the same and I'm lazy. You can't install bohdi or ubunut, because, well, the drivers for flo's hardware aren't there.

Which kernel and rom are you using? Can you get me a log? Get it to bootloop, then use pwr+volume down to enter bootloader, select recovery mode using volume buttons and pres power. When in recovery, the log is /proc/last_kmsg, you can use adb pull /proc/last_kmsg to get it. Put it on pastebin or something and show it to me.

3. Uninstaller
MultiROM uninstaller: multirom_uninstaller-mako.zip
Flash this ZIP file to remove MultiROM from your device. It will erase all secondary ROMs. If you don't want MultiROM menus in recovery, re-flash clean TWRP, but it is not needed - those menus don't do anything if MultiROM is not installed.
4. Flashable factory images ZIPs
I usually release flashable ZIP files based on new factory images from Google, so that you can have clean stock ROM as a secondary system in MultiROM. They are not rooted, no anything, except for occasional small tweaks to make rooting with SuperSU possible. You can find them in this folder on basketbuild or dev-host.

FAQ and other notes
Device encryption
MultiROM doesn't support encryption on Nexus 4 because I don't physically have the device and can't test it.
About security
In order to make multi-booting possible, MultiROM has to sacrifice some security measures. Firstly, on secondary Android ROMs, /system is not mounted read-only. While there are other things preventing malicious software from messing with /system, this might potentialy make it easier for such software to attack that system.
Next, MultiROM doesn't work with /data encryption. Not many people who use custom ROMs also use encryption anyway, so that isn't much of a concern.
What do the ROMs share?
All ROMs are separate, except /sdcard, which is shared between all Android ROMs.
How many ROMs can I have?/Where are the ROMs stored?
You can have as many ROMs as you can fit in your /sdcard. All the ROMs are stored in /sdcard/multirom/roms or on an USB drive. This folder is unaccessible in Android, to prevent mediascanner from scanning it. You can either in recovery, or obtain root and go to /data/media/0/multirom/roms.
Can I have different versions of Android working alongside
Yes. As long as you select "Don't shere kernel" when installing the secondary ROM, the systems are separated.
MultiROM recovery says it's 2.6.3.0. Why isn't it updated to 2.6.3.*highernumber*?
It is, it just shows wrong version.
The menu with all the ROMs won't show up during boot, how to fix it?
Either re-flash the MultiROM zip or go to recovery, Advanced -> MultiROM -> Inject curr. boot sector.
The reason for this is that something rewrote your boot.img, which happens for example when you flash a kernel. MultiROM's boot menu is part of the boot image, so it has to be added into it again.
Will you port MultiROM to device X?
No, probably. I won't port MultiROM to any device I don't own, because it is very difficult to provide the level of support I want to provide if I can't test things myself, as proven by the Nexus 4 port. I'd like to support more devices, but it is also very unsatisfying to work on code for device I don't have - I invest hours upon hours of time for free into it, and then I can't even see it running on the device, so...why..bother..?
I'll probably keep buying Nexus devices and keep porting MultiROM to those myself, but I can't buy every single device - I'm still a student, all my existing devices were bought using some kind of money grant or donations from users.
But, you can port it yourself, the wiki should give you at least some idea how to do that: https://github.com/Tasssadar/multirom/wiki/Porting-MultiROM

Is it possible to use 4.2.2 roms with 4.3 roms at the same time? For example Slim with MIUI

I've got some problems with the current Ubuntu Touch build. (The one from 04-Oct-2013 21:51)
My first ROM is an AOKP (4.3) nightly by Marc Landis.
Then I did this:
I installed the MultiROM zip in CWM.
Then I flashed the other recovery in fastboot.
Afterwards I flashed the patched stock kernel.
Then I installed the Ubuntu Touch zips (both as the installer said).
The first ROM boots as normal.
After some time Ubuntu Touch connects itself to my computer and I see the file manager on my computer with Ubuntu 13.04. I can access the files. However, the screen stays black.
Anyone else having this issue?
Currently, I am downloading the newest build. Let's see if it works with that one.

Ooooh, I love you Tass!

I tested with Ubuntu Touch build from Sept 29. Seemed to work fine apart from missing Wifi and Cell connections. Do these work with later nightlies, did anyone test this?

I tested with Ubuntu Touch build from Sept 29. Seemed to work fine apart from missing Wifi and Cell connections. Do these work with later nightlies, did anyone test this?

I am using this build: http://cdimage.ubuntu.com/ubuntu-touch/daily-preinstalled/20131005/
The one which is marked as "current" didn't work for me.
I haven't tested Wifi or any network operation yet.
Thanks again for testing. :good:

Introduction
MultiROM is one-of-a-kind multi-boot mod for LG G2 mini D618. It can boot any Android ROM as well as other systems like Ubuntu Touch, once they are ported to that device. Besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from USB drive attached via OTG cable (not for D618)
You can also watch a video which shows it in action.
Warning!
It _is_ dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.
Instalation
1.Manual installation
Firstly, there are videos on youtube. If you want, just search for "MultiROM installation" on youtube and watch those, big thanks to all who made them. There is also an awesome article on Linux Journal.
Note 1: Your device must not be encrypted (hint: if you don't know what it is, then it is not encrypted).
MultiROM has 3 parts you need to install:
MultiROM - download the ZIP file from second post and flash it in recovery.
Modified recovery - download the Recovery.zip file from second post and flash it in recovery.
Patched kernel - You can use either one of the stock ones in second post or third-party kernels which include the patch, you can see list in the second post. Download the ZIP file and flash it in recovery.You current rom will not be erased by the installation.
Download links are in the second post.
Adding ROMs
1. Android
Go to recovery, select Advanced -> MultiROM -> Add ROM. Select the ROM's zip file and confirm.
see this video:
How to install secondary ROM
2. Ubuntu Touch - Not available yet
3. Firefox OS - Not available yet
4. SailfishOS - Not available yet
Updating/changing ROMs
1. Primary ROM (Internal)
Flash ROM's ZIP file as usual, do factory reset if needed (it won't erase secondary ROMs)
Go to Advanced -> MultiROM in recovery and do Inject curr. boot sector.
2. Secondary Android ROMs
If you want to change the ROM, delete it and add new one. To update ROM, follow these steps:
Go to Advanced -> MultiROM -> List ROMs and select the ROM you want to update.
Select "Flash ZIP" and flash ROM's ZIP file.
Explanation of recovery menus
Main menu
- Add ROM - add ROM to boot
- List ROMs - list installed ROMs and manage them
- Inject boot.img file - When you download for example kernel, which is distrubuted as whole boot.img, you have to use this option on it, otherwise you would lose MultiROM.
- Inject curr. boot sector - Use this option if MultiROM does not show up on boot, for example after kernel installation.
- Settings - well, settings.
Manage ROM
- Rename, delete - I believe these are obvious
- Flash ZIP (only Android ROMs) - flash ZIP to the ROM, for example gapps
- Add/replace boot.img - replaces boot.img used by this ROM, this is more like developer option.
Changelog

Kernel changes I took from titan-multirom (Moto G) - thanks @myllo.setya for advice.
And how did you change color theme in MultiRom to black? I have red.

MultiROM UI is too big for this device. that features a color change does not appear. so you must enter TwrpMulti->advance->multirom->settings. set rotate at 90 degrees, so you can choose the color on the MISC menu by scrolling down.

I also do not have a PC. I only use my phone for repacking TWRP & MultiRom. basically you need to have a kernel that supports kexec-hardboot. I think it is better you ask @invaderjohn as your kernel developer ..

(I guess stock kernel doesn't support it though, does it?)

Also, do you happen to have a link to a good tutorial about repacking kernels/recoveries on the device?

Introduction
MultiROM is one-of-a-kind multi-boot mod for Nexus 7. It can boot any Android ROM as well as other systems like Ubuntu Touch, once they are ported to that device. Besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from USB drive attached via OTG cable
You can also watch a video which shows it in action.
Warning!
It _is_ dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.
Installation
1. Via MultiROM Manager app
This is the easiest way to install everything MultiROM needs. Install the app and select MultiROM and recovery on the Install/Update card. If the Status card says Kernel: doesn't have kexec-hardboot patch! in red letters, you have to install also patched kernel - either select one on the Install/Update card or get some 3rd-party kernel here on XDA. You are chosing kernel for your primary ROM, not any of your (future) secondary ROMs, so select the version accordingly.
Press "Install" on the Install/Update card to start the installation.
2.Manual installation
Firstly, there are videos on youtube. If you want, just search for "MultiROM installation" on youtube and watch those, big thanks to all who made them. There is also an awesome article on Linux Journal.
MultiROM has 3 parts you need to install:
MultiROM (multirom-YYYYMMDD-vXX-flo.zip) - download the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_multirom_flo_YYYYMMDD.img) - download the IMG file from second post and use fastboot or Flashify app to flash it.
Patched kernel - You can use either one of the stock ones in second post or third-party kernels which include the patch, you can see list in the second post. Download the ZIP file and flash it in recovery.
You current rom will not be erased by the installation.
Download links are in the second post.
MultiROM is compatible with both flo and deb.
Adding ROMs
1. Android
Go to recovery, select Advanced -> MultiROM -> Add ROM. Select the ROM's zip file and confirm. As for the space, clean installation of stock 4.2 after first boot (with dalvik cache generated and connected to google account) takes 676mb of space.
2. FirefoxOS
Download FirefoxOS ZIP package from this thread. The installation is completely the same as Android ROMs.
3. Ubuntu Touch
Use the MultiROM Manager app to install Ubuntu Touch.
Ubuntu Touch is in development - MultiROM will have to be updated to keep up with future changes in Ubuntu, so there's a good chance this method stops working after a while and I'll have to fix it.
Using USB drive
During installation, recovery lets you select install location. Plug in the USB drive, wait a while and press "refresh" so that it shows partitions on the USB drive. You just select the location (extX, NTFS and FAT32 partitions are supported) and proceed with the installation.
If you wanna use other than default FAT32 partition, just format it in PC. If you don't know how/don't know where to find out how, you probably should not try installing MultiROM.
If you are installing to NTFS or FAT32 partition, recovery asks you to set image size for all the partitions - this cannot be easilly changed afterward, so choose carefully. FAT32 is limited to maximum of 4095MB per image - it is limitation of the filesystem, I can do nothing about that.
Installation to USB drives takes a bit longer, because the flash drive is (usually) slower and it needs to create the images, so installation of Ubuntu to 4Gb image on my pretty fast USB drive takes about 20 minutes.
Enumerating USB drive can take a while in MultiROM menu, so when you press the "USB" button in MultiROM, wait a while (max. 30-45s) until it searches the USB drive. It does it by itself, no need to press something, just wait.
Updating/changing ROMs
1. Primary ROM (Internal)
Flash ROM's ZIP file as usual, do factory reset if needed (it won't erase secondary ROMs)
Go to Advanced -> MultiROM in recovery and do Inject curr. boot sector.
2. Secondary Android ROMs
If you want to change the ROM, delete it and add new one. To update ROM, follow these steps:
Go to Advanced -> MultiROM -> List ROMs and select the ROM you want to update.
Select "Flash ZIP" and flash ROM's ZIP file.
Crowdfunding campaign
A crowdfunding campaign to get test devices took place from July 28th to August 27th 2013. Thanks all contributors, the campaign was successful, raising a total of $562. This enabled a purchase of flo and resulted in MultiROM being ported to said device and the code became much more portable.
These people pledged $10 or more and got perk "The Thread" or "The Code":

FAQ and other notes
Device encryption
Since v32, MultiROM supports encryption on this device (it has to be added for each device separately). It works only with Android-based secondary ROMs and the secondary ROMs don't know the device is encrypted, so they would allow you to encrypt the device again - do not do that. If you're using password, pin or pattern for the encryption, MultiROM will ask you for the password on boot. If you're booting the primary ROM, then Android will ask you for the password _again_ - unfortunately, there is no way for me to pass the "unencrypted" status to Android. If you're booting secondary ROM, MultiROM will ask you for the password again after the reboot - that's because I have to unencrypt the /data partition after the ROM's kernel is loaded.
I could omit the second password prompt when booting secondary ROM by temporarily saving the password somewhere, but that's obviously unsafe. So is using encryption with unlocked device though, so I might add this later.
About security
In order to make multi-booting possible, MultiROM has to sacrifice some security measures. Firstly, on secondary Android ROMs, /system is not mounted read-only. While there are other things preventing malicious software from messing with /system, this might potentialy make it easier for such software to attack that system.
What do the ROMs share?
All ROMs are separate, except /sdcard, which is shared between all Android ROMs.
How many ROMs can I have?/Where are the ROMs stored?
You can have as many ROMs as you can fit in your /sdcard. All the ROMs are stored in /sdcard/multirom/roms or on an USB drive. This folder is unaccessible in Android, to prevent mediascanner from scanning it. You can either in recovery, or obtain root and go to /data/media/0/multirom/roms.
Can I have different versions of Android working alongside
Yes. As long as you select "Don't shere kernel" when installing the secondary ROM, the systems are separated.
MultiROM recovery says it's 2.6.3.0. Why isn't it updated to 2.6.3.*highernumber*?
It is, it just shows wrong version.
The menu with all the ROMs won't show up during boot, how to fix it?
Either re-flash the MultiROM zip or go to recovery, Advanced -> MultiROM -> Inject curr. boot sector.
The reason for this is that something rewrote your boot.img, which happens for example when you flash a kernel. MultiROM's boot menu is part of the boot image, so it has to be added into it again.
Will you port MultiROM to device X?
No, probably. I won't port MultiROM to any device I don't own, because it is very difficult to provide the level of support I want to provide if I can't test things myself, as proven by the Nexus 4 port. I'd like to support more devices, but it is also very unsatisfying to work on code for device I don't have - I invest hours upon hours of time for free into it, and then I can't even see it running on the device, so...why..bother..?
I'll probably keep buying Nexus devices and keep porting MultiROM to those myself, but I can't buy every single device - I'm still a student, all my existing devices were bought using some kind of money grant or donations from users.
But, you can port it yourself, the wiki should give you at least some idea how to do that: https://github.com/Tasssadar/multirom/wiki/Porting-MultiROM

I will install it but first i would like to know how to downgrade.
I tried Multirom on CM11. It doesn't seem to work for me. Flashing a second rom to any of the 2 possible location doesn't work. It flashes but the rom is not in "list roms" and i can't find it anywhere on the device using a filemanager. it goes up in smoke.

it is because of o bug in the original twrp multirom theme. i just added a theme which shows the roms, but it works without, too.
the roms are copied to /data/media/0/multirom/roms
and if you flash the cm11 kexec kernel you have to flash the multirom.zip to inject multirom to the new kernel, otherwise you dont have the bootmenu.
the cm11 kernel need some more patches, multirom does not inject.

you did it right, but the cm11 kernel still need some patches.
with blisspop 3.3 it boots cm11 and cm12.1 as secondary roms without problems.

I have "internal" and "/dev/block/mmcblk1p1 (exfat)". When i choose "/dev/block/mmcblk1p1 (exfat)" it asks how big virtual partitions must be. WHen choosing "internal" it doesn't ask this.

it is because the external_sd dont have a ext4 fs, so multirom is using virtual partitions for the secondary roms.
just noticed that my cm11 build env. isnt proper, maybe moonbutt can build the kernel?

[MOD][15-NOV-2016] MultiROM 33 + MultiROM_TWRP_3.0.2-0_20161115 [TestBuild]

Warning!
It _is_ dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is messing with boot sector and data partition. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.
Installation
1. Via MultiROM Manager app
This is the easiest way to install everything MultiROM needs. Install the app and select MultiROM and recovery on the Install/Update card. If the Status card says Kernel: doesn't have kexec-hardboot patch! in red letters, you have to install also patched kernel - either select one on the Install/Update card or get some 3rd-party kernel here on XDA. You are chosing kernel for your primary ROM, not any of your (future) secondary ROMs, so select the version accordingly.
Press "Install" on the Install/Update card to start the installation.
2. Manual installation
Note 1: Your device must not be encrypted (hint: if you don't know what it is, then it is not encrypted).
MultiROM has 3 parts you need to install:
MultiROM (multirom-YYYYMMDD-vXX-UNOFFICIAL-m7.zip) - download the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_multirom_m7_YYYYMMDD.img) - download the IMG file from second post and use
"fastboot flash recovery TWRP-multirom-20150619-v32e-UNOFFICIAL-m7univ.img"
Patched kernel - You can use either one of the stock ones in second post or third-party kernels which include the patch, you can see list in the second post. Download the ZIP file and flash it in recovery.
You current rom will not be erased by the installation.
Download links are in the second post.
Adding ROMs
1. Android
Go to recovery, select Advanced -> MultiROM -> Add ROM. Select the ROM's zip file and confirm. As for the space, clean installation of stock 4.2 after first boot (with dalvik cache generated and connected to google account) takes 676mb of space.
2. Ubuntu Touch this is NOT SUPPORTED AS MOST OTHER PORTS, IF YOU CARE TO ADD SUPPORT, PLEASE DO SO. THANK YOU
Use the MultiROM Manager app to install Ubuntu Touch.
Ubuntu Touch is in development - MultiROM will have to be updated to keep up with future changes in Ubuntu, so there's a good chance this method stops working after a while and I'll have to fix it.
Using USB drive
During installation, recovery lets you select install location. Plug in the USB drive, wait a while and press "refresh" so that it shows partitions on the USB drive. You just select the location (extX, NTFS and FAT32 partitions are supported) and proceed with the installation.
If you wanna use other than default FAT32 partition, just format it in PC. If you don't know how/don't know where to find out how, you probably should not try installing MultiROM.
If you are installing to NTFS or FAT32 partition, recovery asks you to set image size for all the partitions - this cannot be easilly changed afterward, so choose carefully. FAT32 is limited to maximum of 4095MB per image - it is limitation of the filesystem, I can do nothing about that.
Installation to USB drives takes a bit longer, because the flash drive is (usually) slower and it needs to create the images, so installation of Ubuntu to 4Gb image on my pretty fast USB drive takes about 20 minutes.
Enumerating USB drive can take a while in MultiROM menu, so when you press the "USB" button in MultiROM, wait a while (max. 30-45s) until it searches the USB drive. It does it by itself, no need to press something, just wait.
Updating/changing ROMs
1. Primary ROM (Internal)
Flash ROM's ZIP file as usual, do factory reset if needed (it won't erase secondary ROMs)
Go to Advanced -> MultiROM in recovery and do Inject curr. boot sector.
2. Secondary Android ROMs
If you want to change the ROM, delete it and add new one. To update ROM, follow these steps:
Go to Advanced -> MultiROM -> List ROMs and select the ROM you want to update.
Select "Flash ZIP" and flash ROM's ZIP file.
In some cases, you might need to flash patched kernel - get coresponding patched kernel version from second post and flash it to the secondary ROM sama way you flashed ROM's ZIP file.
Explanation of recovery menus
Main menu
- Add ROM - add ROM to boot
- List ROMs - list installed ROMs and manage them
- Inject boot.img file - When you download for example kernel, which is distrubuted as whole boot.img (eg. franco kernel), you have to use this option on it, otherwise you would lose MultiROM.
- Inject curr. boot sector - Use this option if MultiROM does not show up on boot, for example after kernel installation.
- Settings - well, settings.
Manage ROM
- Rename, delete - I believe these are obvious
- Flash ZIP (only Android ROMs) - flash ZIP to the ROM, for example gapps
- Add/replace boot.img - replaces boot.img used by this ROM, this is more like developer option.
- Re-patch init - this is available only for ubuntu. Use it when ubuntu cannot find root partition, ie. after apt-get upgrade which changed the init script.

Current Test Builds
All Current Test Builds can be found on androidfilehost under MultiROM TEST BUILDS
You should be using these, not the ones mentioned below!
Definition of Test Builds: These are stable builds which I have and am using (and testing). They contain the most up to date fixes as mentioned in the changelog under <tba>.
The main reason I'm calling them "Test Builds", is because they have not gone through extensive testing as what I would usually do for a "release version". I think most people would call them release versions, but I tend to be more conservative.
.
The second reason, they get uploaded to AFH instead of directly here, is two fold:
I'm maintaining the M7, M8, M9 and HTC 10 MultiROM versions, and uploading to AFH is easier and faster for me.
Updating the actual threads and posts, is too time consuming every time I want to push an update.
Changelog and NO_KEXEC 4.1 Information can be found in the HTC 10 MultiROM thread.

MultiROM Manager Android app: Google Play or link to APK
You need to have kernel with kexec-hardboot patch only in your primary ROM!
Or you can use the no-kexec workaround v2
AndroidFileHost (mirror & old versions): https://www.androidfilehost.com/?w=files&flid=33970
2. third-party kernels with kexec-hardboot patch
You need a kernel that supports kexec-hardboot in the primary ROM.
Note that although MultiROM, it's recovery, and app are HTC One M7 universal build - they support M7_U/UL (GSM), M7_WLS (Sprint) and M7_WLV) - you need to make sure the kernel you choose/select is for your particular device!!
Some examples for M7_U/UL kernels:
ElementalX - http://forum.xda-developers.com/showthread.php?t=2249774
teaMSeven - http://forum.xda-developers.com/showthread.php?t=2307371
Make sure to flash the proper version for your Android and HTC Sense or GPE version.
More kernels here: http://forum.xda-developers.com/htc-one/#kernels
Make sure the the features of your kernel include "kexec-hardboot (for multirom support)"
3. Uninstaller
MultiROM uninstaller: multirom_uninstaller-20160409-v33b-UNOFFICIAL-m7univ.zip
Flash this ZIP file to remove MultiROM from your device. It will erase all secondary ROMs. If you don't want MultiROM menus in recovery, re-flash clean TWRP, but it is not needed - those menus don't do anything if MultiROM is not installed.

FAQ and other notes
HTC One M7 - Peculiarities / Bugs
You need to be on hboot 1.57 or higher for MultiROM menu to show up at boot time... otherwise it will always boot to primary
.
A few notes about F2FS support: yes the TWRP recovery and MultiROM now do support F2FS, however for that to work "properly" you need a kernel that supports both F2FS and kexec-hardboot in the primary slot and secondary slots
So let's say you formatted your data partition to f2fs, a kernel in primary such as ElementalX (which doesn't support f2fs) won't work (neither in primary nor secondary) and wouldn't even show the boot menu; and a kernel (such as included in CM12.1) that does support f2fs would show the boot menu, but has no kexec-hardboot support, so you won't be able to boot any secondary ROM.
Also, even if you have a kernel that supports both f2fs and kexec-hardboot, remember that it will break any ROM/kernel that don't support f2fs.
Basically, I recommend sticking with ext4
.
A few notes about enabled adb in MultiROM boot menu: later, in the meantime, I still recommend having that disabled.
.
A few notes about the sha1 checks in the installer-script: also later.
.
Something not working, or you need help debugging
Please provide the following information:
a detailed explanation of the problem
.
the recovery.log (found in /tmp/recovery.log or by copying it to the sdcard and then copying it to PC)
.
the link to the thread and name of file (+ which version) you are having problems with
.
due to the large size of some of these ROMs, I may not have time to download and test them, so please also upload the updater-script (found in ROM.ZIP under /META-INF/com/google/android/)
Device encryption
Since v32, MultiROM supports encryption on this device (it has to be added for each device separately). It works only with Android-based secondary ROMs and the secondary ROMs don't know the device is encrypted, so they would allow you to encrypt the device again - do not do that. If you're using password, pin or pattern for the encryption, MultiROM will ask you for the password on boot. If you're booting the primary ROM, then Android will ask you for the password _again_ - unfortunately, there is no way for me to pass the "unencrypted" status to Android. If you're booting secondary ROM, MultiROM will ask you for the password again after the reboot - that's because I have to unencrypt the /data partition after the ROM's kernel is loaded.
I could omit the second password prompt when booting secondary ROM by temporarily saving the password somewhere, but that's obviously unsafe. So is using encryption with unlocked device though, so I might add this later.About security
In order to make multi-booting possible, MultiROM has to sacrifice some security measures. Firstly, on secondary Android ROMs, /system is not mounted read-only. While there are other things preventing malicious software from messing with /system, this might potentialy make it easier for such software to attack that system.
What do the ROMs share?
All ROMs are separate, except /sdcard, which is shared between all Android ROMs.
How many ROMs can I have?/Where are the ROMs stored?
You can have as many ROMs as you can fit in your /sdcard. All the ROMs are stored in /sdcard/multirom/roms or on an USB drive. This folder is unaccessible in Android, to prevent mediascanner from scanning it. You can either in recovery, or obtain root and go to /data/media/0/multirom/roms.
The menu with all the ROMs won't show up during boot, how to fix it?
Either re-flash the MultiROM zip or go to recovery, Advanced -> MultiROM -> Inject curr. boot sector.
The reason for this is that something rewrote your boot.img, which happens for example when you flash a kernel. MultiROM's boot menu is part of the boot image, so it has to be added into it again.

well the previous (dirty) version (that's why i needed to recompile to "e" so as not to cause confusion) has been out for a while, but I guess a new thread does help :laugh:
enjoy, and lemme know if all works well
.... in theory this should also work for Verizon and Sprint users, but I cant test that, since I only have GSM
and for me, the bugs are (always have been)
1- USB OTG doesnt work
2- MTP has to be toggled (on->off->on) for it to work

Thanks @oblikas then @domicq and now @nkk71
Without multirom I'd have been bored of the m7 by now. Thanks guys.

Not at all.
Hopefully you'll get some new users to multirom. Old threads got very confusing for newcomers I think.
Just wanted others to know the solution before reporting it doesn't work.
Also to be clear we don't need the contexts fix anymore? I.e. Just flash Rom, gapps and boot.

nope,
file context fix no longer needed, was added here
layout_version fix (pull request) and (dirty) by-name support for the M7 was added here
only thing i'm aware of it that you'll need at least firmware 6.xx.xxx.x /hboot 1.57or higher
(from domiq's thread)
that will go into post 3, when i'm awake-ish

@mitchst2 can you please tell me which roms are currently supported as you are using it... ?????

Tested OTG out pretty extensively. Although it wil not mount under the mounts menu, it is at least partially mounting it. I can get it to show up in add rom list. I can also get the multirom folder to be created on the usb disk. Install starts, but fails the instant that it attempts to create the data.img. However, after failure, it will show up in rom list on the usb stick. So, at least it has write ability to the usb. Just a bug somewhere now preventing a complete install.
ADDL: The new update gets a bit further. Just getting an error mounging mmcblk0p33 during the data.img deployment.

Has anyone done this yet? I'm a little nervous to try this. I really want to though just don't want to be the first as im still relatively new to adb sent from my paranoid nexus 7

I will certainly be trying this out later. Thanks, will report back with my experience.

Absolutely amazing. Definitely going to give this a shot. Awesome work.

This is fantastic, works a treat here dual booting with latest PA/Trinity. Thanks very much for your work on this Tasssadar :highfive:

How much space is given to ubuntu on a 16gb nexus and what is left for android? can these be adjusted?

Clean installation of ubuntu takes about 1.5gb, but you need at least 2-3gb of free space for the installation process. All data are saved to /sdcard/multirom folder. It is not separated in any way from your normal data - it eats up from the same storage as for example your movies and music.

My understanding of Ubuntu is that it can run microsoft office through the use of a virtual machine, does this support the use of a virtual machine?

Stupid question...I clicked on the Ubuntu link and tried to download the 8gb Nexus image but it doesn't download. It opens it up. No download. Am I doing something wrong? Sent from my Nexus 7 using XDA Premium HD app

I got it working with AOKP 4.2 and Ubuntu, and I'm going to add PA Beta 3 once it gets re-uploaded. 2 android ROMs and Ubuntu! Awesome! Sent from my Nexus 7 using Tapatalk HD
