[CentOS] Uninstalling GAG Boot Manager -- Problem Solved!

Dear friends:

Problem Solved!

I had to donwload a new copy of GAG, install a new copy on a floppy, then 
reboot, switch to diskette in the Bios and only then does the GAG 
install/uninstall menu show up. Clicked on Uninstall and GAG not only 
uninstalled itself from the hard drive but also restored the old MBR. Now 
Centos boots up correctly. Thank God.
