You should be able to just chain load the Debian installation much like 
you would the Windows installation. Just give Debian the hda0 path 
rather than sdaX.

Take my comments as a grain of salt though. I am by NO means an advanced 
user in GRUB. I'm just telling you that I don't see much of a difference 
between the chain loading situations.
