To start, some background: The first thing I did when I got my Encore was find a way to install a clean copy of Windows 8.1 without all the bloatware. I removed all the partitions and let Windows Setup repartition the drive. I did this again when Windows 10 went RTM. This gave me a much larger C: drive than stock, and if you haven't repartitioned your drive then a considerable amount of space is probably being taken up by a recovery partition.
I have tried several different installation methods for RemixOS. If I installed it on the primary partition "C:" then I couldn't find a way to boot it. I tried messing with the BCD and UEFI with various tools to try to get it to show as a boot option in the Windows bootloader, but it didn't work (either I couldn't get it to show up, or it did but thought it was Windows and failed to boot). Because it is 32-bit UEFI I couldn't use EasyBCD + Neogrub. The installer that comes with Remix doesn't do anything notable on this machine (it does add boot options, apparently, but they never display). One problem with this device is that even if you add something to the UEFI boot menu, when you go to the boot menu you will still see only 2 options, even if the entries are there: the SSD and the USB drive. Eventually I found a way to install it by shrinking my C: drive partition and creating a FAT32 partition. This is one of the more popular options right now, but it has some drawbacks when your total storage is only 29GB (or less) when formatted. The biggest drawback is that you are limited to a data.img of 4GB because that is the biggest file size FAT32 supports. Finally today I found what is, to me, the best option for this device and it may work well on similar devices with 32-bit UEFI. After completion you will have a tablet that can dual boot with a simple menu that doesn't require you to make a lot of selections on boot to get to your OS, you will still only have one large partition, and you can have a data.img of 8GB or more.
Eventually this process will probably be streamlined a little more as RemixOS progresses. Maybe they will provide a boot menu option that works with their installer. If not, if I can find a way to install the bootloader that the Androidx86 puts on there I will just do that and skip the installation of Androidx86 altogether. If I can figure out a way to add RemixOS to the Windows bootloader that actually works, I will do that (and I mean properly, right under Windows, not hidden away as an optional boot device).
This process borrows heavily from this page, so credit is largely due to Nirmal Sarkar for handing me the keys. I will also be resharing his download links, or some of them.
Prep:
1. Download RemixOS, obviously--I got the normal 64-bit UEFI download, it works fine. You can also grab the one from the deodexed/pre-rooted thread, it also works
2. Download and install 7-Zip
3. Download and install EasyUEFI
4. Download the Androidx86 Installer
5. Download the Androidx86 ISO
6. Disable secureboot
Install:
1. Extract the RemixOS ISO from the zip
2. Open the Androidx86 Installer and select the Androidx86 ISO
3. Install Androidx86 to C:, choose your data.img size; if you already have a Remix data.img then make it small so it takes less time to install and then delete it and replace it with your Remix data.img later
4. Open the folder C:\AndroidOS\ and delete "system.sfs"
5. Run 7-Zip and open the RemixOS ISO, then extract "initrd.img", "kernel", "ramdisk.img" and "system.img" to C:\AndroidOS\ and overwrite the files that are there
6. Go to "C:" and rename the folder "AndroidOS" to "RemixOS"
7. Save the following as a text file named "grub.cfg"
Code:
set timeout=5
menuentry 'Windows' {
search --file --no-floppy --set=root /EFI/Microsoft/Boot/bootmgfw.efi
chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi
}
menuentry 'RemixOS' --class android-x86 {
search --file --no-floppy --set=root /RemixOS/system.img
linux /RemixOS/kernel root=/dev/ram0 androidboot.hardware=remix_x86_64 androidboot.selinux=permissive quiet DATA=/RemixOS
initrd /RemixOS/initrd.img
}
then move it to the root of your C: drive so that you have "c:\grub.cfg"--you will need to approve a UAC prompt for admin rights to do this since C: is protected (If you want Remix to be the first option, cut the code for the Windows menuentry and paste it below Remix--and if that instruction doesn't make sense to you you probably don't wanna mess with it)
8. Open a command prompt with admin rights and type the following commands:
Code:
mountvol b: /s
b:
cd efi
cd android
copy c:\grub.cfg grub.cfg
and press "y" to confirm
9. Open EasyUEFI--you should see an entry for Android-OS--move it to the top of the boot order
Now you're done. Reboot. You should see the grub boot menu. Press vol+ key to select Remix and Home/Windows key to boot it.
First of all thanks for the guide. Worked like a charm.
But wanted to ask you if you have sound working on your tablet. I've been having this problem since the beginning of remixOS.

No, no sound or screen rotation. No sound on any version of Android based on Android-x86 (I've been playing around a lot the last week with different builds), and the with the versions where screen rotation works it's buggy. Hopefully now that Remix has infused vigor into the Android-x86 community the issue will be solved soon in a future build.
It is a lot easier then that.
Just use http://forum.xda-developers.com/android/software/winapp-android-x86-installer-uefi-t3222483
That didn't support Remix when I made the tutorial. I'm not sure it still works 100% with the Encore. I saw someone made a new tool here just for installing Remix, but I haven't tried it yet.
How is the performance when install on the HD? I have the encore2 10'' and I tried USB install, performance is really bad. I wanted to know if the browsing experience / reading experience is better with android, Windows 10 is not really thought for touch screens.
Hi all,
Just to give you news of a almost perfectly ROM working on this table.
github.com/ouija/android-x86-toshiba_encore2
Using Jide's REMOUNT_RW=1 method to achieve R/W & true root
Both of these methods assume you have used Jide's latest Official Installer for either 32bit or x64 RemixOS 3.x install. This process will extract the system.sfs file, taking up an additional 2.6 gb (something around there), so make sure you have plenty of space for this.
NOTE: For OTA updates, please see the OTA Updates section below.
For RemixOS legacy boot installs (32 & 64 bit) using MBR from Jide's Installer (NON-UEFI)
You will want to make sure you can view hidden and system files in Explorer options (if you need to , google it), Once you do that, travel to C:\RemixOS (or where yo installed it) and using Notepad++ or your code editor of choice, find and open the menu.lst file. Then add a second entry containing the REMOUNT_RW=1 entry like you see below:
Code:
default 0
timeout 10
title Resident mode - All your data and apps are saved
find --set-root /RemixOS/kernel
kernel /RemixOS/kernel root=/dev/ram0 androidboot.hardware=remix_x86 androidboot.selinux=permissive quiet SERIAL=random logo.showlogo=1 SRC=RemixOS/ DATA= CREATE_DATA_IMG=1
initrd /RemixOS/initrd.img
boot
title Resident mode - RW enabled
find --set-root /RemixOS/kernel
kernel /RemixOS/kernel root=/dev/ram0 androidboot.hardware=remix_x86 androidboot.selinux=permissive quiet SERIAL=random logo.showlogo=1 SRC=RemixOS/ REMOUNT_RW=1 DATA= CREATE_DATA_IMG=1
initrd /RemixOS/initrd.img
boot
Once you are done, you can reboot, and choose the entry you added. It will then extract the system.sfs file to a system_dev.img, and mount it as RW for you. Once booted, you can update SuperSU from Play store and enjoy a properly rooted RemixOS
For RemixOS UEFI/ESP installs (32 & 64 bit)
Part 1 You will also want to make sure you can view hidden and system files in Explorer options (if you need to , google it), Once you do that, hit the start menu, and type in CMD, and then right click, and open as administrator. It should look like the window image attached to this post.
Once that is open, type in:
Code:
mountvol X: /S
Then check to see if it is mounted already, (thanks to: @Ventricle)
Start Task Manager; a) CTRL+ALT+DEL -> Task Manager b) CTRL+Shift+ESC c) Right click the taskbar and select Task manager.
Click "File" tab -> "Run new task" -> "Browse" -> "This computer" -> SYSTEM (X or type in "x:" in the filepath bar"
If you cannot access X:, then that could mean one of three things. 1) You have an ESP setup, and just need to scroll down to the ESP System Partition setups section, or 2) You have a legacy MBR setup and just don't know it. or 3) Your setup falls within the other category. Check below for some insight, or the second post for more links to help you figure things out.
ESP System Partition setups
Ventricle said:
I just learned that Windows 10 has EFI partition sometimes already mounted under Z: letter, but it's hidden.
A very quick and easy way to access ESP (EFI System Partition) in Windows 10: (no command line use needed!)
Start Task Manager; a) CTRL+ALT+DEL -> Task Manager b) CTRL+Shift+ESC c) Right click the taskbar and select Task manager.
Click "File" tab -> "Run new task" -> "Browse" -> "This computer" -> SYSTEM (Z or type in "z:" in the filepath bar"
Now go to boot/grub/grub.cfg and edit it accordingly with Notepad++ or other editor
Save the file and your're ready to go
If this still doesn't work - try this:
Ventricle said:
I didn't have any problems with mounting the system (efi) partition in windows, but I've been doing this many times before and using a bit different way:
Run CMD.exe as Admin <- IMPORTANT and enter following commands:
Code:
taskkill /im explorer.exe /f
This will kill explorer.exe process - don't be surprised It's needed, because by default it's ran by "currently logged in user" and it has to be run as Administrator in order to view the mounted system drive. Administrator account is not the same as an account with administrative privileges.
Code:
mountvol X: /s
This will mount the system partition that usually consists of uefi related files. X: is the letter of the drive - you can use whatever letter you want, but it has to be free.
Write:
Code:
explorer
This will run explorer as Administrator and will allow you to browse the mounted system partition.
The above may not work for all devices, as some handle UEFI differently.

Part 2 Now that we have the partition mounter, we can open Notepad++ or your favorite code editor as administrator (the same was as before, right click and open as administrator), and browse to X:\BOOT\grub\ and open grub.cfg (Explorer.exe will not show the mounted partition, so we use Notepad++ as an Admin to do this). Then add a second boot entry containing the REMOUNT_RW=1 entry like you see below: (mine might vary from yours a tiny bit)
Code:
menuentry 'Remix OS_x64' --class android {
search --file --no-floppy --set=root /RemixOS/kernel
linux /RemixOS/kernel root=/dev/ram0 androidboot.hardware=remix_x86_64 androidboot.selinux=permissive quiet SERIAL=random logo.showlogo=1 DATA= SRC=RemixOS CREATE_DATA_IMG=1
initrd /RemixOS/initrd.img
}
menuentry 'Remix OS_x64- RW' --class android {
search --file --no-floppy --set=root /RemixOS/kernel
linux /RemixOS/kernel root=/dev/ram0 androidboot.hardware=remix_x86_64 androidboot.selinux=permissive quiet SERIAL=random logo.showlogo=1 REMOUNT_RW=1 DATA= SRC=RemixOS CREATE_DATA_IMG=1
initrd /RemixOS/initrd.img
}
Save it and also do this for grub32.cfg & grub64.cfg if they are in that directory as well.
Now close Notepad++, then go back to the admin CMD prompt and type
Code:
mountvol X: /D
or if you used Z:
Code:
mountvol Z: /D
This will dismount the UEFI volume for safe reboot.
You can now reboot, and choose the entry you added. It will then extract the system.sfs file to a system_dev.img, and mount it as RW for you. Once booted, you can update SuperSU from Play store and enjoy a properly rooted RemixOS.
RemixOS OTA/Update Instructions:
So you got an OTA notification, or you downloaded the updated .zip from Jide's website. Now what? Well there are a few things we will have to do in preparation for the update. So I will provide a seperate set of instructions for each possible scenario.
While using RW enabled RemixOS
If you got a notification that the OTA was available while using the RW enabled entry, then we are going to have to make some sacrifices to let this go through successfully. First thing we are going to have to do is reboot back to Windows (or your standard OS), and find your RemixOS directory (usually C:/RemixOS/) and look for the system_dev.img file and delete it (yes, I am serious, just hit the delete button). This will of course cause a few of your ROOT apps and tweaks that were written to system to vanish, so after we are done, you will have to reapply/reinstall those.
Now we can reboot and make sure you choose the NON-RW boot entry for RemixOS. Once in RemixOS, go ahead and check for and apply the OTA update as normal. Once the update is complete, you can re-create the RW image by simply choosing the RW enabled boot entry.
Using the .zip from Jide's website
If you ended up grabbing the .zip file for the updated version of RemixOS, then we can upgrade manually with no issues usually, but you will have to do this from Windows (or your OS of choice).
Start by opening the .zip and extracting these files over the ones already in the RemixOS folder:
initrd.img
ramdisk.img
kernel
system.sfs
I also replace the install.img and isolinux.sys files, but I don't think they are needed. I'm just lazy and drag it all over from the .zip
The next step is that same as the OTA update. You now have to delete your system_dev.img file. Once that is done, you can reboot and choose the RW enabled boot option to extract the system and enable RW.
Ubuntu based Instructions:
And for users who are running this on Ubuntu based systems, please follow @Cyborg Ninja's instructions below:
Cyborg Ninja said:
Hi guys, for those who use Ubuntu and want the RW feature, open Grub customizer, if you do not have:
Code:
sudo apt-add-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
Then, highlight your RemixOS and click on the little pencil to edit.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then insert REMOUNT_RW=1 here after the "CMDLINE" and it will look something like this:
Code:
insmod part_gpt
search --file --no-floppy --set=root /RemixOS/system.sfs
linux /RemixOS/kernel root=/dev/ram0 androidboot.hardware=remix_x86_64 androidboot.selinux=permissive CMDLINE REMOUNT_RW=1
initrd /RemixOS/initrd.img
Save, reboot and boot up your RemixOS and it will do the rest, have to wait a couple minutes and you are all set. This will even let you remove the preinstalled superuser it came with and install Chainfire's SuperSU in its place.
Click to expand...
Click to collapse
Using EasyBCD or other methods
If you have installed RemixOS using EasyBCD with the .iso or similar method, you will need to remove your install, and then reinstall with a modified ISO.
Extract the .iso file to a folder on your computer, and inside that folder, you will see a few folders and then the .img files and such. To start, navigate to efi/RemixOS/ and add the second RW entry to the grub.cfg, grub32.cfg & grub64.cfg like the UEFI instructions from above, but no need to mount the UEFI partition here.
Once those are done, navigate back to the root of the extracted ISO, and then go to boot/grub/ and add your second entry to the grub.cfg in there too, use the Resident Mode entry from that though as your base, just adding the REMOUNT_RW=1 line to a copy of it. Save, exit, and go back to the root of the extracted ISO again.
Now enter the isolinux directory, and edit the isolinux.cfg file, adding the REMOUNT_RW=1 line to a copy of the "residentmode" entry. Save, exit,back to root of the extracted ISO again.
Now select all the files and folders, and using 7zip or comparable application, zip them all back into an .iso file. Then you just have to install this like you would normally using EasyBCD. Just a reminder though. This method is not recommended. I recommend using Jides installer or the roll your own UEFI method. Also, since I have no way of testing this method, I cannot verify it will work 100%. Awaiting user feedback on this
I hope this helps some of you get what you need with root. I personally create a separate root entry in my grub.cfg that let's me select standard or R/W, so in the event of an OTA update, it should be able to complete without issues.
Again, Thanks goes out to Jide, @Ventricle, @lollyjay, & @Cyborg Ninja for all the help so far on this

In my case, I did not. If you have the .ISO still, you could always delete it and extract it later for OTA.

Delete system.sfs after system_dev.img created will make remix stuck on boot so the result is do not delete the system.sfs
Thank you @electrikjesus for this method. It's definitely the best out there as it doesn't hinder OTA updates and requires nothing but <3GB of additional storage and small change in grub.cfg file.
Other methods require changing initrd.img with system r/w properties and even if someone would want OTA, he'd have to keep a copy of system.img/.sfs file for swapping.
Best method for now.

Mounting EFI/System partition
@lollyjay Remix OS can be installed on 32bit UEFI as well - I successfully installed it on my Asus T100TA using the official tool and to my surprise... it works. For releases 2.0X I used Android-x86 installer, but now even official version works.
Anyway, I didn't have any problems with mounting the system (efi) partition in windows, but I've been doing this many times before and using a bit different way:
Run CMD.exe as Admin <- IMPORTANT and enter following commands:
Code:
taskkill /im explorer.exe /f
This will kill explorer.exe process - don't be surprised It's needed, because by default it's ran by "currently logged in user" and it has to be run as Administrator in order to view the mounted system drive. Administrator account is not the same as an account with administrative privileges.

This will mount the system partition that usually consists of uefi related files. X: is the letter of the drive - you can use whatever letter you want, but it has to be free.
Write:

A very quick and easy way to access ESP (EFI System Partition) in Windows 10: (no command line use needed!)
Start Task Manager; a) CTRL+ALT+DEL -> Task Manager b) CTRL+Shift+ESC c) Right click the taskbar and select Task manager.
Click "File" tab -> "Run new task" -> "Browse" -> "This computer" -> SYSTEM (Z or type in "z:" in the filepath bar"
Now go to boot/grub/grub.cfg and edit it accordingly with Notepad++ or other editor
Save the file and your're ready to go
@lollyjay and others, let me know if it works for you - Windows 10 Home here.

Hey I think I found a method that will work for all Windows 10 UEFI installations. I have tried it on three different laptops, with the only thing same is UEFI and Windows 10:
1 Right click on the Window at left end of the taskbar
2 Select "Command Prompt (Admin)"
3 At the command prompt (assuming you don't have a z drive), type: mountvol z: /s
4 At the command prompt, type: notepad.exe
5 When Notepad window opens, select File/Open
6 In lower right of the notepad open window, set to "All Files (*.*)
7 Navigate on the left column to the z drive and click on it
8 Select boot and then grub then open grub.cfg
9 Navigate to the space between " logo.showlogo=1 DATA= "
10 Add: REMOUNT_RW=1 so it is " logo.showlogo=1 REMOUNT_RW=1 DATA= "
11 Select File/Save to save your modified grub.cfg
12 Select File/Exit
13 At the command prompt, type: mountvol z: /d
14 Close the command window
15 Reboot to RemixOS - you should see it writing the new system image file
Hope this helps some who are not experts

Yeah, I guess any notepad app will do. I didn't even think about using the built one app cause I'm so used to my fancy notepad
I have successfully installed Remix OS on my Acer Switch Alpha 12 with dual boot Win 10 and Remix OS and most of the things work great. Can anyone here share a guide on how to change the default boot up to Windows 10 instead of Remix OS as per the attached screen capture and possible to shorten the waiting time from 30 seconds to 3 seconds maybe. I have tried to edit it from Windows 10 as per attached screen capture but there show only Windows 10 and no Remix OS.
Use EasyBCD application in Windows
I tried EasyBCD and in UEFI mode but I didn't proceed further as I got this error
"EFI Bootloader Detected!
EasyBCD has detected that your machine is currently booting in EFI mode. Due to limitations set by Microsoft, many of EasyBCD’s multi-booting features cannot be used in EFI mode and have been disabled."
Not sure if safe to proceed, but all advise is most welcome...
Okay... I don't own a UEFI machine to trial so lets try another way. Open start menu in windows and in search enter 'msconfig' then enter. A small windows will open showing you boot option. Choose Windows 10 and set it default. Then reboot to see the results.

The "msconfig" is similiar with the screen capture that I attached. Only show windows 10 and no others

Try something and tell me what is the result:
Hold the mouse pointer over the window on lower left of screen
Right-click and select the option Command Prompt (Admin)
Allow the command prompt
At the next screen type: mountvol x: /s
If you do not receive an error message then type: cd x:\
If you see a prompt with X:\> then we can continue from there; post what you found

Hi,
I can mount X: as per your guide and can access to X:\ by typing "x:" but not "cd x:". However, I have already mapped my network drive on to X:\. Is this ok?
Well since you are already using X then try again using another letter such as Z

I already mapped Z to my another network drive. I tried "mountvol u: /s" which is not mapped to any drive but got the "The parameter is incorrect."

I just went through this process this week. I had the same question as you, and did alot of experimentation to get the solution. This is how it works on my system (Lenovo tablet, Windows 10 Pro, Remix OS, dual boot using Grub boot loader).
Okay, ignore what you've done so far.
Assume we have a first-time installation of Remix OS.
My instructions will only help you in this situation.
I can't really correct any experiments you may have done after that.
1) When the Remix OS installation tool tells you to reboot, don't do it. Just exit it, and restart after we finish the steps below.
2) Open command prompt as an Administrator.
3) Mount your boot partition by following these instructions. I think you may have had problems with past advice because it is not so clear. This tutorial has clear steps:
Code:
http://linuxbsdos.com/2015/09/05/how-to-delete-grub-files-from-a-boot-efi-partition-in-windows-10/
4) Navigate to the following folder (change drive letter "Z:" to whatever you used to mount the boot drive):
Code:
Z:\Boot\Grub\
5) Edit the file "grub.cfg"
6) To set a default OS, that the Grub boot loader always highlights:
- Search grub.cfg and ensure the entry menuentry 'Windows' is above menuentry 'Remix OS'.
- This basically indicates that Windows is the first option in the boot menu, and Remix OS is second.
- Search grub.cfg and find the entry set default="${saved_entry}"
- Replace it with set default=0
- This basically tells the Grub boot loader to highlight the top entry (Windows) everytime it starts.
7) To change the countdown timer, that the Grub boot loader uses:
- Search grub.cfg for set timeout=
- Replace it with set timeout=3 (you can change "3" to whatever countdown number you like)
8) OPTIONAL! To set the default OS to repeat whatever was last selected:
- Suppose in the future, you want the the Grub boot loader to automatically highlight whatever OS was selected last.
- In my situation, the Remix OS installation tool has a glitch where it makes "Remix OS" automatically selected every startup.
- To correct this, repeat all the actions to mount the boot drive & edit the grub.cg file (see "6)" instructions).
- Search grub.cfg for menuentry 'Windows'
- In the line under it, add the text: savedefault
- Search grub.cfg for menuentry 'Remix OS'
- Ensure that somewhere in the lines below, the text savedefault exists. If not, add it manually.
- The problem, in my situation, was that the Remix OS installation tool only added "savedefault" to the Remix OS entry...and not the Windows entry. By adding that line to both OS's, the Grub bootloader can properly tell which OS was selected last & choose it for you on startup.
piece of cake. modify this on your Grub line
set default="${savedefault}" <--------change to this
function savedefault {
saved_entry="${chosen}"
save_env saved_entry
menuentry 'Windows 10' --class windows {
savedefault <-----------Add this(Tells it to always highlight Windows)
search --file --no-floppy --set=root /EFI/MICROSOFT/BOOT/BOOTMGFW.EFI
chainloader (${root})/EFI/MICROSOFT/BOOT/BOOTMGFW.EFI
Go to the RemixOS line and remove savedefault from that line and done. Now it will always boot with Windows highlighted
set timeout=30 <---------Modify 30 to whatever youd like for Timeout
I made a batch file for Easy Mounting of the EFI partition. It's set up to use drive Z, so if you have a drive Z already, modify my batch file to use whatever drive you'd like. Extract and run as Admin

See this for solution: www*reddit*com/r/RemixOS/comments/5pz2u1/boot_screen_selects_remix_os_by_default_has_30/dcvrl1m/
Just change the star to dot in url. They won't let me post links yet.

Are you guys installing Remix on a UEFI setup? I can help with both issues as I've just recently changed both of those exact settings. I made Windows 10 the default boot setting and changed the timeout as well. Someone please post the grub.cfg lines and I'll show you what to change to get what you want. If on a UEFI setup you need to mount the EFI partition in windows which is usually hidden. I made a batch file to auto load the EFI partition and from there you can edit the grub.cfg file to your liking. Download the file i posted, run as admin and it should load the EFI partition for you. If you need any help I could always teamview with you and show you. It's literally a 2 minute job.

You guys may also be interested in my custom RemixOS that comes with SuperSU and Xposed as well. That's located in the forum
I wrote the guide below for another user. It should help you as well:

Thanks for procedure but can you paste the exact text that come from final editing of grib.cfg. I change text like you said but there may be misunderstanding that lead to failure.
