i still have no idea what you're doing that causes it to ask for older versions of systems. i've reinstalled systems repeatedly on my computer, and i've never seen that. it does that when you boot from a cd only, without loading windows?
if that doesn't work, unplug your hard drive, boot to the disc, and when it loads up properly plug in your hard drive again. i should point out that you need a sata drive for this to work.
