Comment 3 for bug 426238

As a temporary work round at the grub line hit e and change to the following

set quiet=1
insmod ntfs
set root=(hd0,3)
search --no-floppy --fs-uuid --set f6863c88863c4b7f
linux /ubuntu/disks/boot/vmlinuz-2.6.31-9-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro \
quiet splash
initrd /ubuntu/disks/boot/initrd.img-2.6.31-9-generic

then hit ctrl-x

This will then boot.

*DON'T CHANGE YOUR UUID NUMBER TOO MINE LEAVE IT BE*
*change root=/dev/sda1 to whatever your disc should be*
