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 a new module called `bli`, and the updated grub configuration refers to that module, causing grub to fail on boot.
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/mountsto 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.
