[erikdubois]

Symptom:
You boot up into the firmware of your motherboard.

reason:
grub update broke the system

Solution:
Downgrade the grub package

Code: Select all

sudo downgrade grub

choose versions 261 or 297
say yes to adding it to pacman.conf to ignore that package
type "update-grub" in a terminal


Option 1 : it is TOO late you can not boot - you see the firmware from your motherboard
Solution 1 : clean install and do not update grub or downgrade it after it after all the updates came in. Always end with typing "update-grub" in a
terminal.

Solution 2 : more technical - learn about chroot and downgrade grub that way

How to move from grub r261/r297 to release r322?

We need to type a line or an alias to be able to boot again with grub.

Code: Select all

install-grub-efi

or the content of this alias

Code: Select all

sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi

Then we type

Code: Select all

update-grub 

or the content of this alias

Code: Select all

sudo grub-mkconfig -o /boot/grub/grub.cfg

If we know the solution we can automate it with a pacman hook.
