GRUB (stuck on screen)

[J.V.]

I have a linux system - on another system, I cut a bunch of Windows 
rescue CD's (that are based on Linux) and was trying them out.

I think it may have been the Kapersky rescue live CD, not sure, so it 
booted, I did not run a rescue or anything, just wanted to see if it 
would boot.

Now when I boot my Linux system, I get a black screen and all white 
letters that say: "GRUB" and that's it.  It hangs there.

How to unstuck it?
