If we're talking about different physical drives, the NT/2K(/XP?) bootloader 
assumes it's running from the first BIOS drive in the system and pukes 
otherwise (i.e. if it's been chained from a different boot program).  I never 
could get it working on separate drives with boot0, but here's an excerpt 
from my grub configuration:

title Windows 2000
root (hd1,0)
makeactive
chainloader +1
map (hd0) (hd1)
map (hd1) (hd0)

grub has a nifty feature that intercepts and translates BIOS calls to remap 
drives -- enough to keep the NT loader happy anyway.  Once enough of the 
system is up that the real 2k disk driver is loaded, it should work fine.
