GRUB failure

[Bret Busby]

Hello.

I have a "laptop" computer with winXP Pro, Unbuntu 8.04 and Debian 5 (I 
think it is 5), installed.

With a recent electricty supply failure, I ran an orderly shutcown on 
the computer.

Since that shutown, each time that I reboot the computer, it takes me to 
the FRUB prompt 9rather than the GRUB boot menu), and I cannot bot the 
computer into any operating system.

How do I get GRUB to configure itself, to detect the installed operating 
systems so the computer is usable once again?

Or, has GRUB destroyed the software build of the computer, and all of 
the data, requiring a complete reinstallation of all of the operating 
systems installed on the computer?

Thank you in anticipation.
