It worked thank you! But I had to use more commands:
- modprobe efivarfs (EFI variables not supported)
- for i in /dev /dev/pts /proc /sys /sys/firmware/efi/efivars /run; do sudo mount -B $i /mnt$i; done
- cp -r /lib/modules/5.15(tab-to-complete) /mnt/lib/modules (from: Unable to boot into Qubes - #13 by syspacket)
