[SOLVED] Cannot access arch partition after failed kernel update

Hello everyone,

I'm facing an issue while trying to access my arch linux partition after an aborted kernel update. My laptop battery died during the installation process, and ever since then, I haven't been able to access my arch partition. I have tried several solutions, but none of them seem to be working.

When I turn on my laptop, it only shows the "Reboot into firmware interface" option, and nothing else. I tried chrooting into my arch partition, reinstalling the kernel from the pacman cache, and reinstalling GRUB, but it still doesn't work.

However, I can see the bootloader-id in my boot device options, but when I select it, it says "error: disk cryptouuid not found."

Can anyone please suggest a solution to this problem?

Thank you !

Re: [SOLVED] Cannot access arch partition after failed kernel update

when you say "aborted kernel update" are you referring to a full system update (pacman -Syu) ?
if so, how far did the update get ? and what was the list of packages in the update ?

Yes, it was updating the kernel + some packages.

Downloading was done, it was during the installation phase.
I really don't remember any of the packages...

Hey, sorry for the late response. I just managed to fix my issue. Turns out the problem was with systemd-boot, not GRUB!

Here's what I did to resolve it:

_ Mounted my root partition with /dev/sdX to /mnt.
_ Mounted my /boot partition with /dev/sdaY to /mnt/boot.
_ Chrooted into my Arch Linux installation with arch-chroot /mnt.
_ Installed the linux and mkinitcpio packages using pacman -S linux and pacman -S mkinitcpio.
_ Regenerated the initramfs with mkinitcpio -P.
_ Updated the systemd-boot configuration with bootctl --path=/boot update.

And voila, the problem was resolved! Thanks!
