GRUB & Sarge & Win XP

[Alessandro Ciorcalo <a.ciorcalo@gmail.com>]

Hi,
I installed Win XP on my secondary hard drive e only then installed
Debian Sarge on primary hard drive. Now I am trying to run Win XP from
grub using these lines:

title Windows XP Professional
#map (hd0) (hd1)
#map (hd1) (hd0)
rootnoverify (hd1,0)
chainloader +1
makeactive
boot

I tried with uncommented "map" lines but I always get a "missing
ntldr" error message. Do you think I got Win XP boot files erased
during debian installation?
I think there's nothing wrong in the script I am using.

Thanks in advance,
