Yes, I think so. When I try to start it says:
Verifying DMI pool data......
error: file not found.

Which I think means that grub suddenly can find the boot sector, which 
is strange as before the upgrade it worked flawlessly. I don hope that 
the upgrade messed with the boot sector but I have some tools to find 
that out.
