You don’t need Grub Customizer to set your default boot option.
This is done in /etc/default/grub
, usually without any change.
- Remove-uninstall Grub Customizer
- Compare
normalgrub
andgrub-btrfs
relevant package files
pacman -Ql grub | grep "etc/grub.d"
pacman -Ql grub-btrfs | grep "etc/grub.d"
against
existing files
ls -1 /etc/grub.d/
and delete what does not belong to them.
3. Re-create grub.cfg
update-grub
