Brad,

>From the GRUB Manual:

3.3 Installing GRUB using grub-install

	_Caution:_ This procedure is definitely deprecated, because there are several 
possibilities that your computer can be unbootable.

Grab a copy of the GRUB Manual & read parts 3, 3.1 & 3.2 which will describe 
how to create a GRUB boot floppy & then install GRUB to the MBR.

Cheers!
