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

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 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

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.

Hi i installed remix os in a tablet with bios uefi32, but when i installed write grub in the efi partition.
Now only i can select remix os in grub menu.
I try live cd linux, mount efi partition, and modify grub.cfg to add windows 10, but i lost /EFI/Microsoft/Boot/bootmgfw.efi and dont boot
How can i repair?

What you can try is the following:
- Boot up from the Windows 10 installation DVD
- Select your language and keyboard, click on Next
- Click on "Repair your computer"
- Click on "Continue" (this will only work if the Windows installation DVD recognizes your Windows 10 installation)
Windows 10 will now be booted from the installation DVD
Now do the following:
- Download EasyBCD
- Open up EasyBCD and click on "Add New Entry"
- Click on the Windows tab and select your Windows version in the "Type: " box
- Give your new boot entry a name like "Windows 10"
- Select the proper drive where Windows 10 is installed
- Click on "Add Entry"
Congratulations, you just added the Windows 10 boot entry again!
Thanks for your answer. i repaired with console administration from windows installation.

Already booted it with win 10 pro..and fixed every issue..still thanks for the replay
1. Create a second ext4 partition for Remix OS using Gparted
You should delete the linux-swap and the extended partition first. After reducing the size of your Ubuntu partition sda1 you can create your Remix OS partition sda2.
Finally you'll create a new extended partition containing the linux-swap.
http://postimage.org/index.php?lang=german
2. Install Remix OS into the new partition
Use the steps described in "Installing Remix OS to Hard Drive or Virtual Machine without additional tools", but there are a few differences:
- Skip step 3, because you have a formatted ext4 partition already (in my example: sda2)
- Step 4: Select sda2 for your installation (formatting of sda2 not needed)
- Step 5: Do not install a boot loader GRUB; do not install EFI GRUB2 (you'll customize the Ubuntu boot loader)
3. After a reboot Ubuntu will start. Please install grub-customizer
sudo apt-add-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
4. Start grub-customizer and add a new entry (Ctrl + N) named e.g. "Remix OS", Type "other"
Boot sequence:
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd0,2)'
linux /android-2016-07-12/kernel quiet root=/dev/ram0 androidboot.hardware=remix_x86_64 androidboot.selinux=permissive SRC=/android-2016-07-12
initrd /android-2016-07-12/initrd.img
(hd0,2) has to be changed if you use a partition other than sda2 on hd0 for Remix OS.
Example: If you are using sdb2 on hd1 the "set root" command is
set root='(hd1,12)'.
You can obtain the Android path (e.g. /android-2016-08-11/) by mounting the Remix OS partition with the Linus file manager.
Example of boot menu entry for Remix OS
http://postimage.org/index.php?lang=german
If you are working with the Remix OX 32bit version you have to use ". . . androidboot.hardware=remix_x86 . . ." in the last line (beginning with linux).
Example: With version 3.0.103 (2016080805) 32bit the line has to be:
linux /android-2016-08-08/kernel quiet root=/dev/ram0 androidboot.hardware=remix_x86 androidboot.selinux=permissive SRC=/android-2016-08-08
initrd /android-2016-08-08/initrd.img
5. Make the Remix OS entry the second boot menu entry
http://postimage.org/index.php?lang=german
6. Modify the General Settings
- Default: first entry
- Show menu
- Start default after 5 seconds
http://postimage.org/index.php?lang=german
7. Save the new grub configuration
8. Check the new swap UUID and correct it in /etc/fstab
sudo blkid | grep swap
9. Reboot and select the second entry "Remix OS"
Thanks for the guide it's really useful for me since I'm already using ubuntu and had a separate partition ready for another OS.

I have changed only "insmod part_msdos" to "insmod part_gpt" since I'm using GPT/UEFI (I'm running it on an old mac mini, only boots UEFI)
Any idea what might be wrong? I already triple-checked the grub entry and stilll can't figure out what's going on. Tried also editing hd0,# on boot to no avail either.
EDIT: Would it be easier to have it as single OS? I already backed up and cleaned the HDD.

Are you sure it's (hd0,3)?? You may have to recheck that. Enter the command mode by pressing 'c' at Grub menu and execute 'ls' command to list partitions. I guess it must be (hd0,gpt3) or something like that. You can double check which is RemixOs partition by using 'cd' into each partition executing 'ls' to list files.
Thanks Thisu, but no dice, I even tried installing RemixOS as the main OS without any luck. I have used crappy linux installers (like way back knoppix) but damn Remix takes 1st prize. Right now I'm trying to reinstall GRUB2efi from an ubuntu live USB. No matter what kind of installation I do for Remix I get the typical "blank" GRUB screen (the one that states "....minimal bash command...." and a GRUB> prompt)
I don't know what's the matter with this installer, it's never consistent. sometimes it asks for a data file creation, sometimes doesn't, sometimes just reboots after the install, sometimes prompts what to do... Resident mode tends to work but from this particular drive and computer, is barely useable due to poor speeds. And trying to repurpose an old mac with this is far worse, the PoS won't even try booting a normal MBR scheme. it HAS to be EFI

I am no GRUB specialist, and I do not use EFI. I found a working GRUB configuration for Remix OS by copying and modifying the primary GRUB configuration for Linux Mint 17.3. The tool I used is the "grub-customizer". I installed Remix OS in partition sda2, and "set root='(hd0,2)' " worked for me.
I created and formatted sda2 using GParted; so during the Remix OS installation sda2 did not have to be formatted. Because I wanted to use the Ubuntu GRUB installation, the Remix OS installer has been told not to install GRUB und EFI GRUB2.
In case if someone still looking for help, use the example below. I was successfully able to boot with configuration below.
All you have to do is to mention right gpt partition where you have installed remix os mine was gpt6.
Then by running the "blkid" command in ubuntu terminal find the UUID of the partition
Replace my UUID which is in this example with yours.
Instead of root=/dev/ram0 use root=UUID of the partition.
Hope it will help some

Installing Ubuntu first is at least easier, because Ubuntu will not detect Remix OS as "installed system" and will not offer installing Ubuntu as second system, providing dual boot.
ok, i have finally install everything,followed what have been put here.
but i get an error once i choose remix os on GRUB
error '/android-2016-07-12/kernel' not found
error 'you need to loadthe kernel first'
@remixtester
Firstly, thanks for the guide. I've got it mostly figured out but I have a couple of questions for you.
The partition I have installed Remix to is sdb12, so how would I edit the grub? Is it:
Code:
set root='(hd0,12)'
or
Code:
set root='(hd1,12)'
or something completely different?
Answer:
sdb = hd1 so the code is:
Code:
set root='(hd1,12)'
Also, the "/android-2016-07-12 has to be changed if you will use a Remix OS version other than 2.0.403 (2016-07-12)" section might need a little more clarification. I understand that I need to change this because I'm using Version 3.0.104, but there's no indication in this guide on how to find the correct information for builds that differ from the one you mention using. So how do I find out what to change that line to (as per the build I downloaded)?
Answer:
Mount the partition you installed Remix to in the Linux file manager and view the folder there.
Even though I've answered my questions I'm leaving this here for anyone else having the same questions in future. It might be a good idea to add this info to your guide.

(hd0,2) has to be changed if you use a partition other than sda2 for Remix OS
/android-2016-07-12 has to be changed if you will use a Remix OS version other than 2.0.403 (2016-07-12)
Example of boot menu entry for Remix OS
http://postimage.org/index.php?lang=german
If you are working with the Remix OX 32bit version you have to use ". . . androidboot.hardware=remix_x86 . . ." in the last line (beginning with linux).
Example: With version 3.0.103 (2016080805) 32bit the line has to be:
linux /android-2016-08-08/kernel quiet root=/dev/ram0 androidboot.hardware=remix_x86 androidboot.selinux=permissive SRC=/android-2016-08-08
initrd=/android-2016-08-08/initrd.img
5. Make the Remix OS entry the second boot menu entry
http://postimage.org/index.php?lang=german
6. Modify the General Settings
- Default: first entry
- Show menu
- Start default after 5 seconds
http://postimage.org/index.php?lang=german
7. Save the new grub configuration
8. Check the new swap UUID and correct it in /etc/fstab
sudo blkid | grep swap
9. Reboot and select the second entry "Remix OS"

Which version of Remix OS did you use? 32bit or 64bit?
What's the name of the partition where you installed Remix OS?
Did Remix OS start after you clicked OK here:
http://postimage.org/index.php?lang=german
Which boot sequence did you enter into the boot menu entry for Remix OS (Ubuntu "Grub Customizer")?

Actually i did a mistake. Infact its a mistake in your code for boot sequence in your guide
In eg of 32 bit , you have written initrd=/andoid..... And correct is initrd /android......
Anyways hardly matters, your guide was awesome. Thank you !!!
helpp
I followed every step on the guide, but when I try to boot Remix Os, it just says "disk /dev/ram0 doesn't exist", I don't know what to do, I've tried changing /dev/ram0 for other disks and dir,, but just says the same "disk -the disk I decide to put- doesn't exist
also, sorry for my bad english, I mostly speak spanish
Ok everything went ok boots up and runs fine. my question be if you were going to root this you would want it to be after you make the bootable usb which will then change it to system.img and make the change on the grub customizer then install it to the partition with "Tab" INSTALL=1.
error when trying to start Remix OS
After the procedure, when I tried to start the operational system an error appeared "error archive '/android-2016-07-12/kernel' not found. alloc magic is broken at 0xb798ee00: b76cfc20." . How can I find the correct name of the kernel I had installed to make some changes in the grub costumization.
Thanks.
Label RemixOS partition as RemixOS using gparted and use the script in below link either through custom grub entry or grub-customizer.

I've just installed Remix OS 3.0 official version from Remix Website. Everything works fine and smoothly. However, everytime I boot up there is a GNU Grub dual boot, which let me choose windows 10 or Remix OS, and the count-down time is 30 seconds, which is too long. I've searched and tried to do some Grub commands but it seems not correct.
So anyone with this knowledge please help me please, just wanna change it to about 5 seconds, which is perfecly suite me. Thanks alot
I am using the Dell XPS 9350.
Updated:
1./ Change the value in the msconfig boot doesn't affect the GNU GRUB
2./ Change the value in the Grub.cfg file in RemixOS/boot/grub/grub.cfg doesn't work also

@robocopvn are u using UEFI or legacy boot?
Second thing - be more informative when it comes to thread title. I'll be critical here, your thread title is terrible, please edit it accordingly.
For legacy, you need to edit the grub.cfg or menu.lst file in RemixOS folder - u can edit both, it won't hurt.
For UEFI, you need to edit the grub.cfg file in /boot/grub folder on your ESP (EFI system partition) - full path EFI(f.e Z: letter):/boot/grub/grub.cfg
UEFI instructions - BEWARE, ACCIDENTALLY REMOVING FILES FROM ESP PARTITION WILL RENDER WINDOWS NOT BOOTABLE - WILL REQUIRE RECOVERY TOOLS.
To access ESP, you need to:
start cmd.exe as administrator
Kill Explorer -> Mount the ESP -> Start the Explorer as admin using below commands:
Code:
taskkill /f /im explorer.exe
mountvol Z: /s
explorer.exe
Edit & save the grub.cfg file - change value of line:
Code:
timeout
Reboot and test if the changes worked(if you reboot into Windows, the ESP should be inaccessible again - it automatically unmounts upon restart)

thank you, I am using the UEFI.
I start the cmd.exe as administrator.
The first command (taskkill /f /im explorer.exe) works and kill the explorer.exe
the second command mountvol Z: /s showed "the directory is not empty"
and the third command just start the explorer again.
So could you please guide me how to edit the grub.cfg properly.
P.s:/ I can access the grub.cfg in /boot/grub/grub.cfg and edit it with notepad (just like how we edit build.prop in android) and it doesn't work.
Thank you. And I will change my thread title !

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:

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

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.
