Grub rescue - error: unknown filesystem
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?
