How would I go about doing this, though? grub doesn’t have journalctl, and booting the LiveISO and trying that isn’t actually useful: it only shows errors coming from the LiveISO - and the computer doesn’t actually boot, this error being the very reason.
I thought of trying to rebuild initramfs-linux.img because the problem seems like it is coming from there. However, I am unsure of whether I should do it or not. I don’t want things to break even further.
