I found that this happens when the partition device names have changed.  Grub
cannot find the /boot/grub/ folder.  All that you are seeing runs from the MBR and first
couple of sectors.

I don't have the link to the webpage right now, but you basically boot from a line CD,
and install grub.  Grub should automatically find the correct partition to load from.

There is no grub menu as I have seen previously. After the text
