You DO NOT have to wipe your hard drive or "downgrade" to run windows XP on a vista computer. Download and install Microsoft Virtual PC. its free and will allow you to run another operating system in a window of the current one you are running. You can have both!
Yes, you can delete windows 7 by formatting your drive, but all of your files will be gone. If you have two hard drives, you can either copy your data from one drive to the other or put xp/vista on the second one and use the windows 7 drive as a slave.
Check that you have no disks in either the floppy disk drive, or the cd/dvd drive. Check that there is only one operating system installed... if you have Windows Vista and Windows XP then the computer will need to know which one you wish to use.
Install Win XP on the first hard drive, then install Vista from Xp and on question about "what kind of installation do you want to have?" Answer "separate" installation. When it asks you "which hard drive are you going to use?" Choose the second one. Vista will create a boot list automatically.
