Install XP. XP install will destroy Linux boot manager.
Then fix boot by reinstalling only boot manager (GRUB).
http://www.dedoimedo.com/computers/grub-2.html
Section 4.G. tells how to reinstall GRUB 2. (you will be able to do this after booting from Ubuntu 10 liveCD and opening terminal)
p.s. Sections 4-5 cover how to manually edit things in that case if automatic install will fail to detect all 3 OS'es.
