grub_is_using_legacy_shim_lock_protocol while booting
Problem; : You are using the old GRUB, probably because an upgrade broke or you didn't run grub-install when needed.
EndeavourOS EXAMPLE, commands need to be modified for your distribution, not modifying these will may your PC un-bootable
Boot in to the Live Installer for the OS (probably what you installed the OS from).
Open gparted from the applications menu and search for your drive in the top right hand corner.
OPTIONAL : IF you have an encrypted drive (LUKS) you need to "open" the drive, so it can be mounted.
In Gparted an encrypted drive will look like this:
Take the Partition name and put it in to the command
<code>sudo cryptsetup open /dev/nvme1n1p2 endeavouros</code>
Open the console app
Mount the root (/) partition
sudo mount /dev/nvme1n1p2 /mnt
sudo mount /dev/mapper/endeavouros /mnt
Also mount the boot (/boot/efi) partitions
sudo mount /dev/nvme1n1p2 /mnt/boot/efi
Enter an Arch chroot, this will only exist on Arch based systems.
sudo arch-chroot /mnt
Reinstall GRUB
grub-install
Press Ctrl+D to exit the chroot, then type reboot to restart the system and everything should work.
