Just install Xp by booting from the cd or dvd drive. (Make sure the drive is set to boot first) In the Xp setup, it will ask you where you want to install the Operating System. You would then choose where you want to install it. But first make a partition so you CAN install it. It should do it automatically when you choose the drive (i haven't installed xp in a while) but if not, partition it so it is NTFS and it will setup the files. Then when you start up, you will choose which operating system to boot. If you prefer (I recommend) disconnect your vista drive that way you are 100% sure you will not install over it. I'm not sure what hard drive you should get though.
