Base System
grub 2.12
When upgrading existing installations using grub on UEFI systems, make sure to update the installed bootloader before rebooting, otherwise your machine might not boot.
The problem is that grub added new configuration that executes fwsetup --is-supported. The problem is that grub 2.06 does not supported the --is-supported argument yet, causing grub to unconditionally try to reboot into firmware.
Here is an example assuming the default setup. Don't blindly copy this examples but verify what's applicable to your system.
EFI
# grub-install --target=$target --efi-directory=$efi_directory \
--bootloader-id=alpine --boot-directory=/boot --no-nvram
# install -D $efi_directory/EFI/alpine/grub$fwa.efi $efi_directory/EFI/boot/boot$fwa.efi
- target
- The relevant target for your system
- efi_directory
- Either /boot/efi or /boot. Run
awk '$2 ~ /boot/ && $3 ~ /fat|msdos/ { print $2 }' /proc/mounts to confirm.
- fwa
- The respective firmware architecture for your system
Short-term work-around
A short-term work-around to get the system bootable again is to restore the backup configuration:
cp /boot/grub/grub.cfg.back /boot/grub.cfg
This should allow you to boot the system again to fix it permanently. This will be reverted again when either grub or the kernel is updated again.
This will only work if update-grub has not been executed any more since the upgrade to grub 2.12.
