I don't know if it helps at all, but my menu.lst is set up with this at
the end (automagically added, not manually by me, I might add):

title		Microsoft Windows XP Professional
root		(hd0,0)
savedefault
makeactive
chainloader	+1

I don't know if the extra lines "savedefault" or "makeactive" would get
rid of the error message, just posting this as an example of a working
grub menu item! (My dual-boot is from the same hdd, windows and then
ubuntu partitions). 

Were you following instructions from this list or an online how-to?

Good luck sorting the issue out,
Josh
