Comment 7 for bug 550559

Same here except my GUI never loads. So basically this error has bricked my Ubuntu installation. I have gone into recovery mode and tried all of the options:

dpkg - fix broken packages
netroot - terminal with networking
grub - update grub
failsafeX - supposed to boot into a failsafe version of X but just goes to a blank screen....

I tried booting other kernels but the same story....
