Hi,

A Google search brought:
<http://www.linuxquestions.org/questions/linux-kernel-70/booting-vista-via-grub-invalid-or-unsupported-executable-format-516870/>

To sum up, if you insert = between title and Windows XP, and add
makeactive, changing to:

title=Windows XP
rootnoverify (hd0,0)
makeactive
chainloader +1

It might help?
