Order to install Ubuntu Studio and Xp?

[MayhemGuitars]

Hello, I am about to finally install a linux OS! I currently have vista on my computer. I plan on dual booting ubuntu studio, and windows XP. I read the dual boot guide, however it only covers when you already have the windows OS installed. My question is then, do i install XP, then Ubuntu Studio, or should i install that first, and then XP?
Thanks for any help.

XP first as grub will recognise windows partitions, but the windows boot loader won't see ubuntu.
