Hi. I have manjaro installed on lvm and a partition where grub is. System boots and works perectly but grub doesn’t show. Grub shows me a black screen instead of a menu and then the system boots. I tried to press enter and other keys so it wrote to me “sparse file not allowed”.
I tried to follow advice on the internet. I ran “grub-install” many times. I replaced
GRUB_SAVEDEFAULT=true
GRUB_DEFAULT=saved
to
GRUB_SAVEDEFAULT=false
GRUB_DEFAULT=0
in /etc/default/grub
I tried to comment these lines in /etc/grub.d/00_header
set recordfail=1
# if [ -n «\${have_grubenv}» ]; then if [ -z «\${boot_once}» ]; then save_env recordfail; fi; fi
}
but didn’t found it.
When I ran update-grub it wrote to me
warning: Couldn't find physical volume `pv5'. Some modules may be missing from core image..
warning: Couldn't find physical volume `pv4'. Some modules may be missing from core image..
warning: Couldn't find physical volume `pv3'. Some modules may be missing from core image..
warning: Couldn't find physical volume `pv2'. Some modules may be missing from core image..
warning: Couldn't find physical volume `pv1'. Some modules may be missing from core image..
Maybe someone knows how to fix these bugs? Help me please.
