# Fix ma uefi boot shit:
# useful info at: https://www.linuxbabe.com/command-line/how-to-use-linux-efibootmgr-examples
# - from bios start EFI shell then:
# fs0:
# \EFI\Manjaro\grubx64.efi
# this will boot grub, so we can go in manjaro and open a shell
# in the shell:
# check the current entries:
sudo efibootmgr
# add grub if missing (you can check the device name with df for the -d flag):
sudo efibootmgr -c -d /dev/nvme0n1 -p 1 -L Manjaro -l \EFI\Manjaro\grubx64.efi
# run to get the numbers:
sudo efibootmgr
# set boot order:
sudo efibootmgr -o 1,0,4
