This is telling you that the boot loader has become corrupted, and is crashing. A leading cause for this would be hardware failure -- something gone wonky with your hard drive. Try booting the 'fixit' system from the installation media and see if you can fsck and access the filesystems on the disk -- it may be a localised problem that's killed the ability to boot from the drive leav= ing the rest unaffected. Or the entire drive may be toast, and you've got no option other than to get yourself a new drive and restore from backup. Actually, given the fairly cheap price of disks nowadays, I wouldn't try too hard to fix up the original disk: if you're going to=20 have to spend some hours working on it, it's more economic to ditch the old one and start afresh.
