In Windows, are there some command lines that would make the machine understand that Android should be the next boot (for one boot only -so once I reboot from Android I fall back into Windows)?
I am working on a notebook ASUS X200CA, UEFI-based machine, dualboot: Windows 8.1 and Android 7.1 (two different partitions). When Android is installed, I get Grub2, so at reboot I can manually choose between Windows or Android. However, I want to be able to switch OS programmatically.
Basically, I am looking for the equivalent of Linux - efibootmgr -n xxxx or grub-reboot x before using reboot - that I could implement on Windows.
I tried to use bcdedit /enum firmware to check the ID associated to Android then ran bcdedit /bootsequence {ID}. At reboot, this led to an error like:
File: \efi\Android\BOOTx64.EFI Status:0xc000000d Info: The application or operating system couldn't be loaded because a required file is missing or contains error
(NB: secure boot disabled, fastboot disabled)
I tried to use EasyBCD, but since this is an UEFI-based machine I didn't get very far.
I added Android to Windows Boot Loader using BOOTMGR, restarted, got to Windows Boot Loader, found the Android option, manually picked it and got the same error message (see above).
I tried Grub2win, you can modify the EFI boot order with it, but it seems that it's not for one boot only.
I know that some tablets dual boot Windows-Android have wintoand.exe that allows to switch but I am not sure what's behind. Moreover, I would prefer to not have to use any software: I want to know what command lines can achieve what I need.
If you have some ideas of how to solve this or anything to read that could guide me, Thanks for sharing in advance!
I believe Grub2Win has the function you are looking for. Documentation will be found in the Grub2Win help under keyword Reboot.
The command format is:
C:\grub2\grub2win reboot x
where x is the menu selection number. This can be run from the Windows command line or a .bat file.
You will receive a message that the reboot has been scheduled.
If you wish to cancel a previously scheduled reboot, use this command:
C:\grub2\grub2win reboot none
Hope this helps.
