The problem here is that  if you install Windows XP after installing 
UBUNTU, UBUNTU's GRUB has no way of knowing that Windows XP has been 
installed.  That's why it's better to install Windows XP before 
installing UBUNTU.... An entry in /boot/grub/menu.lst  for Windows XP is 
automatically created during the UBUNTU installation if Windows XP has 
already been installed.

Other than reinstalling UBUNTU after Windows XP has been installed,  you 
can  try  to edit  /boot/grub/menu.lst  in UBUNTU  and  insert an entry  
to boot Windows XP .

Run an editor to get /boot/grub/menu.lst and type the following:, 
preferably just before the entry for UBUNTU:

         title Windows XP    (hda1)
         root (hd0,0)
         chainloader +1

Do a   save or save as   to save the modified menu.lst.
