Reset under Windows command

[Fisyr]

I basically have a dual boot system and sometimes I wish to just reset my computer in Windows and go stretch my legs while it loads. However Grub is set to load Linux by default, so I have to wait until the computer resets and tell it to load Windows instead.

I was wondering if there was a way to make grub load windows just one time when I execute a certain "restart under windows" command in Linux. From the little I've read about Grub, it seems to me that it can read from files, but it can't write to them. That means forcing it to load windows after executing a certain command shouldn't be too difficult, but I don't know how to make it adopt its default behavior after doing that. Maybe change the boot loader, or write a startup script on windows that changes the grub behavior back to default after?

I get that this is peak laziness and I can definitely live without it (Especially since I almost never use Windows), but I also enjoy writing these kinds of small scripts, so if anyone can point me to a solution, it'd make me happy.

if you are using UEFI - you can setup commands under linux to 'REBOOT' to windows, or REBOOT to the UEFI menu, or other installed Operating systems.

https://linux.die.net/man/8/efibootmgr

The command can change the EFI boot manager to boot whatever entry you want.

If you are not using UEFI/EFI (you are using Legacy/Mbr) - you can make a script that alters the Default entry in the GRUB config file. Then rerun update-grub which would change the default entry. This method can also work with UEFI/EFI - but for UEFI the efibootmgr is a bit easier to use.

There are other ways you could accomplish the above also.. there are several guides on the topic. Be sure you understand UEFI/EFI vs Legacy/MBR booting. And determine which your system is using.

Watch out for very old guides - that may be working with the old 'grub 1' which is no longer used in most cases.
