Like I said, (hd0,0), refers to the first partition on the hard drive, in other words, hda1. If you have a hard drive with only one partition on it, that partition would be (hd0,0). Normally you will not want to run setup (0,0), because this will setup stage 1 grub on hda1. You would still need then to have some form of bootloader on the mbr as well. Often all that needs to be typed at the grub prompt is:
grub> root (hd0,0)
grub> setup (hd0)
This is assuming that your /boot is on hda1. For contrast, hdb2 (second partition on second hard drive) would be (hd1,1).
Hope this helps.
