Hrmph, did you try my page?  

http://home.nyc.rr.com/computertaijutsu/grub.html

It's dated, but I ~thought~ I explained that one well for the beginner. 

Basically, unlike fdisk or cfdisk, grub starts numbering from 0, like
many programs.  

So, your windows partition is probably /dev/hdb1---err, yeah, it is, you
said so.   :)

So, you would want

hd1,0

In other words, your first hard drive, holding ubuntu, is, by Grub
standards, hd0.   The first partition is hd0,0, second partition hd0,1,
etc.  

So, the second drive is hd1, and the first partition on that drive is
hd1,0.  

Take a look at the link I posted above, see if that explains it clearly.
If it doesn't, let me know as that page is supposed to be newcomer
friendly (though I don't really maintain it anymore, so, I dunno)

Hey, no problem, just send me money.  :)
