Got the same issue using ubuntu-10.04.1-alternate-amd64.iso. I run a MD RAID for the root but have a small ext2 partition at the start of the first drive for /boot.
Was the fix in 10.04? If it was then it did not work for me.
I recovered by live booting a CD, installing mdadm, assembling the RAID, mounting all the partitions, chroot'ing into the fresh install and then running grub install (see: https://wiki.ubuntu.com/Grub2#Recover Grub 2 via LiveCD)
