First start grub with the command grub. At the grub command prompt tell it the location of the files needed by grub:
root (hd2,0)
Where, in this case, the files are on hard disk hd2, partition 0. You can optionally check that the files are there with:
find (hd2,0) /grub/stage1
Note that this did not work for me! However I continued and everything ended up rosey. The final step is to install grub on the Master Boot Record (MBR) with:
setup (hd0)
This will install grub on the MBR of hd0. Finally quite grub:
quit
