[SOLVED] Grub doesn't seem to start

Hey,
today i ran an update and rebooted. And was greeted by an error saying "hybernation device 'UUID=..." not found.

I use a LUKS setup with an unencrypted boot partition, and an encrypted main partition. The UUID in the error is the one of the mapper device for the encrypted partition.

So I prepared an arch install stick, opened the luks partition mounted it to /mnt mounted the boot partition to /mnt/boot and ran arch-chroot /mnt
I had set grub TIMEOUT_STYLE to hidden, so i changed it back to countdown and the GRUB_TIMEOUT to 3, and ran `grub-mkconfig > /boot/grub/grub.cfg` which seemed to be successful.

I have no idea why that problem suddenly started occuring, but I thought "maybe, regenerating the grub config is enough, and if not, I can then edit out the kernel parameter in grub, and boot anyway". The problem is, I can't start grub anymore. My laptop boots into the UEFI setup, even though the boot partition is set as primary boot target. If I use the dialog to select the boot target, and choose "Arch" it will simply not boot, and the dialog will stay open. I have no idea why, I also have not Idea why this upgrade broke anything.

Any kind of help is welcome.

Please post your HOOKS line from /etc/mkinitcpio.conf.

Re: [SOLVED] Grub doesn't seem to start

It's

HOOKS=(base udev autodetect modconf block encrypt filesystem keyboard resume fsck)

I also have this btw:

MODULES=(amdgpu)

probably irrelevant, but I mention it for the sake of completeness. By now I also tried reinstalling Grub, which didn't change anything btw.

Are you able to boot the fallback image? If so, try rebuilding the initramfs.

I'm not aware of any fallback image, but I could rebuild it from the install image. And now booting works again. Thanks a lot.
