Step by step:
1) pop in your Red hat Cd1 cd which is bootable. When you get greeted by the welcome screen asking you for input type "linux rescue"
2) At the rescue prompt, you should see a few options, one should be "reinstall bootloader"
3) that is what you want, and if you see anything else you might need, go for it, but just fix the bootloader first.
you should be able to take out the cd and reboot with grub there.
