GNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project.



GRUB does not boot

If you ever run into a situation where GRUB refuses to boot, here’s one possible fix:

error: file `/boot/grub/x86_64-efi/priority_queue.mod` not found.
Entering rescue mode...
grub rescue>
  1. Boot from a PantherX ISO or USB
  2. Select command line
  3. Repair GRUB by following these steps

This is assuming you’re on an EFI system with two partitions on /dev/sda. Adapt as required.

mkdir /tmp/guix
mount /dev/sda2 /tmp/guix
mount -t proc none /tmp/guix/proc
mount -t sysfs sys /tmp/guix/sys
mount -o bind /dev /tmp/guix/dev
mount /dev/sda1 /tmp/guix/boot/efi

Chroot into your system, run the guix build deamon and reconfigure:

sudo chroot /tmp/guix /bin/sh
guix-daemon --build-users-group=guixbuild --disable-chroot &
guix system reconfigure /etc/system.scm
