A long time gone, but I remember the easiest way is to install grub on a 
new drive using an already running grub (you have it as you said).

In the grub console, you have to give something like

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

The first line tells grub where /boot (=root in grub terminology) is 
located - a seperate partition /dev/hda1 in this example, YMMV. If you 
have /boot as a directory on say /dev/hdb1,
	grub> root (hd0,0)
should do it.

The second line installs grub in the MBR of /dev/hda. Before this, there 
must be some files copied over to /boot/grub/, taken from
/usr/share/grub/i386-pc.

I know, some people don't like 'info', but
	info grub
is worth reading ...
