Windows XP installition button greyed out?

[Photoshoper]

When I put in Windows XP the button where it says "install" is grayed out so I can't click it =( why is this and how do I fix it so I can put windows xp back on my computer. I have Windows 7 at the moment...

Boot from the Windows XP CD, delete the partition, format as NTFS and reinstall XP.

Yea, you can't install windows from within windows no matter what version.

I disagree Sturm. You can DOWNGRADE windows from within windows, but you can UPGRADE. For the poster to go from Windows 7 to anything else, they will have to boot off the CD and go through a new install including deleting and recreating the partition(s).
