Looks like the Master 80G has Windows and the Slave has Linux instead - 
but you might have just mistyped it here.

There is some helpful troubleshooting information for GRUB here:
http://www.gentoo.org/doc/en/grub-error-guide.xml
which was derived from this thread:

That guide suggests that booting Windows from the second hard drive 
/boot/grub/menu.lst entry look like:

title Windows XP
   map (hd0) (hd1)
   map (hd1) (hd0)
   chainloader (hd1,0)+1
