Recent changes in `grub` added a new command option and changed the way the
command is invoked. Depending on your system hardware and setup this could
cause an unbootable system due to incompatibilities between the installed
bootloader and configuration. After a `grub` package update it is advised to
run both, installation and regeneration of configuration:
grub-install ...
grub-mkconfig -o /boot/grub/grub.cfg
For more specific information on `grub-install`, please refer to the wiki:
