Grub installation

I was reading through he archives and found several posts regarding grub
installation problems.  I too have this problem and am in search of what I
need to do different to fix this.  My first drive (hd0,0) is a win2000 disk
and the second drive (hd1,0) is the gentoo disk.  when running grub I got an
error about unrecognized partition.  This occurred when I tried to run root
(hd0,0).

What do I need to change here?  My partitions are ext3 /dev/hdb1,3 and swap
on /dev/hdb2.

I think I'll have to boot from the installation CD and do the chroot
commands listed in the install docs - right?  I pretty new in to gentoo, but
have played around with other distributions with some success.

Should I be running root (hd1,0) in grub instead?  The install docs seemed
to lead me install on the MBR of the first disk.  The archived messages seem
to back this up.

Any assistance appreciated.
