Trying To Downgrade To XP

[Sil3nc3]

I currently have Windows 7 Ultimate, and I want to downgrade back to Windows XP. I lost my XP disk but I have an .iso that I backed up (Still have my serial key). But when I run setup.exe from the .iso its shaded out where it says "Install Windows XP." How do I reinstall Windows XP from an .iso file on Windows 7!?

Please Help!

Burn the ISO to CD using Imgburn at 4X speed with Verify. It never fails.

Boot from the CD, delete partitions, create New as desired, full format and install.

Burn it to a CD...unlike Windows Vista and 7, Windows XP requires access to an installation CD at all times.

Is it possible to make a bootable partition so I can install it on my second partition?

Windows XP requires access to an installation CD at all times.

Well when I was using Windows XP I was aloud to reinstall from the iso though.
