Try:

title windows1
root (hd1,0)
makeactive
chainloader +1

Which Windows entry you should use depends on which drive you are booting on start up, and also you didn't mention which NTFS partition has Windows on it. It looks like XP might be on sda1, so how about trying:

Code:

title       Windows XP (hd0)
root       (hd0,0)
chainloader +1

title       Windows XP (hd1)
rootnoverify     (hd1,0)
map        (hd0) (hd1)
map        (hd1) (hd0)
chainloader +1

If neither of those work, let me know what exactly happens when you try them from the Grub menu.

thanks kilgoretrout and CJS!
i got boot back to normal by using:

title Windows XP (hd1)
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

once again, thanks!
