Your problem is that you installed Windows 7 first. You'll have to start from scratch. Back up any data you may have on either drive or partition.
You need 2 separate drives (or 2 partitions) set up on your computer. You can do this during the Windows XP setup. Once you finish doing the setup for Windows XP where you are able to control XP you'll then need to restart your PC with the Windows 7 Disk. Set up Win 7 on the second drive or partition (this is after the WinXP installation) and once everything is completely installed and ready for use you should have the option to choose between each OS.
