repair

I have had bad experiences with 12.04 on my laptop, too many things just dont work so am wiping it and replacing with Windows 8 release preview to get it running again. Anyway, I installed normally, deleted partitions and formatted and installed windows fine, but now there is an error coming up when it boots: error: unknown filesystem grub rescue>

Ive tried repairing from Windows 8 disk, doing FixMbr and FixBoot but hasnt worked, neither has reinstalling.

Any ideas how to get rid of this?

12.04 upgrade broke grub? (not wubi related)

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation… >>> More
