Comment # 2 on bug 903736 from Mircea Kitsune

I'm can't confirm 100% that this is what did it for me. But after upgrading
from 13.1 to 13.2 via "zypper dup" yesterday, on both my laptop and PC, grub2
was completely broken. It would only show a few lines of text flickering on the
screen, then said that I must load a Kernel first.

I coult only fix my system by booting into the recovery console from the 13.1
DVD, and making a completely new grub2 install. This is a really severe bug,
which others might not know to fix as easily... I hope it will be looked into
soon.
