In short, you have wiped out GRUB. Assuming you are using Legacy GRUB:

  • Boot into rescue mode from the install CD/DVD

  • At the superuser prompt, type in the following commands, noting that the first command will put you at the grub prompt, and the next 3 commands will be executed there. Also note that (hd0,0) implies the first hard drive and the first partition on that drive, which is probably where you had grub installed. If not, then adjust accordingly.

#grub
> root (hd0,0)
> setup (hd0)
> exit

Then modify grub.conf as necessary and reboot.

If you are using GRUB2, the process is similar but the commands are slightly different. Refer to GRUB2 documentation.
