I'm not a grub expert but I suppose there is an entry in 
/boot/grub/menu.lst like this:

title Windows
root (hd 0,0)
savedefault
makeactive
chainloader +1

The line "root (hd 0,0)" tells grub to use the first partition of the 
first disk. If you change it to "root (hd 1,0)" it should boot from the 
first partition of the second disk instead. I don't know if Windows will 
like booting from the second disk, though.
