I have been trying for a few hours to set up grub2 to recognize windows11. I don’t understand why but os-prober can’t find it either. I can boot to windows11 from my bios and I don’t have any issues there.

In my system windows is installed in nvme0n1p3
lsbk output:

When I execute:

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

I get:

Generating grub configuration file ...
Adding boot menu entry for UEFI Firmware Settings ...
done

OSs windows11 and Fedora 36

You should check the solution posted here

@ilikelinux Fedora uses /boot/grub2/grub.cfg since this change in F34
