Had the same problem here. Reason was here, that the UID of the LVM
partitions (on top of a nvidia fake raid) got mixed up. UID where used
in the /boot/grub/grub.conf file and in /etc/fstab.

I booted from DVD in rescue mode, mounted the partitions manually and
modified the files using the /dev/mapper/...  notation
(or /dev/Vol00/... in my case). There was no need to re-install grub
into the MBR or something like this.
