Power loss during system upgrade

[Mowteng]

My laptop experienced power loss during a system upgrade and now I can’t get past grub. I suspect I have the same issue as described here;

Unable to boot into Linux: Vmlinuz-linux Not Found

Since upgrading my packages with the “pacman -Syu” command, Linux gave me the following errors when trying to boot it up: “Loading kernel linux …” “error: file ‘/boot/vmlinuz-linux’ not found.” “Loading initial ramdisk …” “error: you need to load the kernel first.” Grub works fine, but I can’t seem to boot my EndeavourOS partition specifically because of this. What should I do?

However when mounting I get an error “wrong FS”. If someone could tell me what commands you need to see to help me I would greatly appreciate it

We would need to see both the commands you are running in the live session to recover and the output of:

lsblk -o name,type,fstype,size

[Mowteng]

Thanks! Worked flawlessly, however mkinitcpio -P returns an error

[root@EndeavourOS liveuser]# arch-chroot /mnt
[root@EndeavourOS /]# mkinitcpio -P
==> ERROR: No presets found in /etc/mkinitcpio.d

[dalto]

Reinstall your kernel

pacman -Syu linux linux-headers

[Mowteng]

After that re-run mkinitcpio -P?

[dalto]

@Mowteng

re-run mkinitcpio -P?

No, that should be run as part of installing the kernel.

[Mowteng]

Thank you so much! You saved me hours of trial and error.
