Re: Windows 11 not booting from grub

Hi, sorry, "not booting" is no helpful info.
- does the grub boot entry for windows 11 show up ?
- what happens exactly, when you choose it ?

To be sure, your boot mode is EFI, not old legacy BIOS /MBR mode ?

And please post the content of /boot/grub/grub.cfg and the output of:

sudo blkid
lsblk --fs
