No thats not the case… If I have no idea at this moment, then I don’t answer. And it is bad if only one person answers. More heads produce better results… (something like that). So @andreas85 explained it in an excellent way.
So on /boot there are initramfs. These initramfs are not rolled back and therefore it crash. I guess an easy fix could be:
- chroot like explained above
- recreate initramfs:
mkinitcpio -P
- recreate the grub menu:
update-grub
