|Hello guys! I've been updating from 10.04 to 11.10 yesterday, and got the same problem. As long as I understood t is not a OS issue, but a screen's. Grub is there but you can't see it. I followed the next solution, easy and it worked: |
1. When you see "Sync Out Of Range" screen, do nothing and let Ubuntu start up automatically.
2. Once you are in Ubuntu, open a Terminal and type:
3. Once installed, open it with Terminal (i've got lost in Unity Desktop) typing
4. Strangely, grub screen configuration wasn't too high, but too low! i've changed it to the next level, closed it, started up again, and voliá! here was the old grub.
Hope it helps!
