Seems grub is corrupted in your system, you need to reinstall the grub, try this:
Quote:
grub> find /boot/grub/stage1
if you get for example (hd0,1),then
Quote:
grub> root (hd0,1)
will install grub from that partition and
Quote:
grub> setup (hd0)

It could be a hard drive problem. If grub can't find the partition with the boot/grub directory it can't read its files. Could be a hard drive problem, device names changed, bios problems maybe due to a low battery, bios settings remapping hard drive order,etc.
You may want to boot up using a live distro and and check each partition.
