deleting ubuntu partition and reassigning unallocated

I realize this is more a gparted concern, but am having a user name problem and not getting in to their forum.
My spouse is reaching a critical space issue in XP and needs to recapture the assigned Ubuntu space to windows.
I can delete it easy enough with gparted live CD, but am lost with reassigning unallocated.
Please advise and thanks

Hi:

Try to download this live cd
Hiren's BootCD 10.1 - www.hiren.info ( you can find a lot of info =)

and use acronis or paritition magic....
