During the upgrade from 11.10 to 12.4, I got stuck on a screen with background image, and nothing else.

I restarted the computer, and after GRUB menu, screen gets black with cursor blinking.

I've tried getting into text mode, by removing quiet splash, and by adding text, but it leads to the same black screen.

So, I cant get to both text or graphical mode. I'm stuck on GRUB menu. What can I do to get it working again?

When I restarted, the upgrade was interrupted, and therefore I couldn't boot on the last kernel.

I had to boot the previous kernel on text mode, and resume upgrade via sudo apt-get upgrade. At some point it passed me a command using dpkg that resumed the instalation.
