Thanks Pete, that worked perfectly.  Not sure why the automount from
the rescue CD wouldn't work, but manually mounting /dev/sda1 worked. 
I was able to do the grub-install that way.  That drive now boots,
though I get a Grub Error 21.  Seems to be related to grub.conf on
that drive reference hd1.  Not sure how that got that way, since my
original restored image was only hd0 (single hard drive).  Anyway I
think all I have to do is clean up grub.conf on that drive.  I'm going
to work on that today.

Thanks for the tip.  Still new to this.  Just learned how to "bottom
post" a few weeks ago :-)
