I installed a GRUB theme and changed some options in the config but now I need to run update-grub (alias for grub2-mkconfig -o /etc/grub2-efi.cfg) after every kernel update or else that new kernel version won’t boot. Does anybody know a fix for this?
I just tested it, enabling
GRUB_ENABLE_BLSCFGfixed the issue. Unfortunately, submenus don’t work with it enabled. That was probably why I disabled it. Thanks for your help.
