Reinstall Windows 11 without killing Ubuntu installation?
by Calab from LinuxQuestions.org on (#6JJ2V)
Currently, my computer boots between Windows 11 and Ubuntu Linux. Each installation is on their own drive. I choose which OS to use with the Grub menu.
I want to erase the entire Windows drive and reinstall Windows 11 fresh. I'm sure that this will mess up my dual booting system somehow. If it would make things easier, I would consider wiping the Linux drive as well and reinstalling. All my data will be backed up on a third HDD.
This is an EFI system, so I also need to worry about where the EFI partition lives.
Normally, I would just disconnect the Linux drive and do the installation, but it's a M.2 drive that would require a lot of disassembly to remove.
How can I be sure that grub is currently installed on the Linux hard drive and not the Windows drive?
Any advice before I start breaking things?
