how to install windows xp on windows 7 without any virtual version

Need more details, exactly what are you trying to do, start at 1st step.
You can't install XP "on the windows 7" except in a virtual machine. If you are trying for a clean setup, you are not installing it on Windows 7. Exactly what happens when you try to install XP? What computer band/model is this? What type of XP disk is it?
