Crash during update, now won't boot after grub

Hi,

I'm a bit at my wits end and I'm at the limit of my knowledge.

I was updating arch using pacman -Syu as I often do. Pc crashed during the update and now the pc wont boot. It's stuck on the ROG logo right after grub.

What have i tried to do to fix it, I thought if I could chroot from a live usb, i could update and everything would be fine. Nope.
I decrypted my drive to /dev/mapper/decrypted
Mounted on /mnt mounted the efi to /mnt/boot/efi
Ran arch-chroot /mnt
And finally ran pacman -Syu
Rebooted and i'm still stuck at pre-boot.

I ran journalctl -b but no entries were found

And now I don't really know what to do next

Also I'm on the phone which is my only way to post here so I dont think I can post pictures of my screen to show the results of dmesg

Any help is greatly appreciated

There is a nice wiki article on this topic that might be of help here: https://wiki.archlinux.org/title/Pacman … ed_upgrade

Did you also maybe try to regenerate the initramfs i.e. by reinstalling the kernel package or running "mkinitcpio -P"?

Unfortunately for that procedure, I already didnt have any logs from pacman that allowed me to see which packages where installed/failed. I ran a command to reinstall all packages.

I did run mkinicpio -P and nothing changed

I just noticed that right before the logo appears, i think initramfs executes successfully. Not sure if thats worth anything.

Thank you for your suggestions

Re: Crash during update, now won't boot after grub

So you think you're reaching the graphics part but then it just crashes? You could try to switch to the tty (Ctrl + Alt + F4 (or any other F-key)) and extract logs like for xorg or the kernel.
