What I want is a clean install of Win 7, using an Upgrade CD, without any extra space being taken up on my drive by old XP stuff.
Then get the cleanest possible install, by booting from the Win7 Upgrade installer, choosing Custom then Advanced tools: Delete your XP partition and any others you don't want, create new one(s), then format and install.

The Upgrade installer will scan your disk when it first boots up and see the XP to allow you to insert your key and later activate when you get online at Computer>Properties activation link.

Are you saying that Windows 7 gets it in its brain that you have XP on your machine, the very first time you boot from the upgrade CD, and retains this information in it's brain, even though you've deleted the XP partition?

What happens if there is a problem with the install and you've deleted your XP and you have to do it again?

Not exactly. My point is that if you have XP on the hard drive, then you don't necessarily have to start the clean install from XP, but can get a cleaner install by booting from the Upgrade installer so that you can delete and format your XP. If you do this, then the installer has the ability to see the XP when it scans the HDD at first boot up. It then passes a flag that allows you to insert your product key and later activate, even it you delete and format the XP during this process.

If you already have a wiped hard drive, then you need to do a workaround that allow you to install the Upgrade on a clean HDD: This is perfectly legal as long as you have a qualifying XP or Vista OS which is then no longer usable. Just keep the qualifying key with your Upgrade key in case the question should ever arise during reinstallation and reactivation..

However reinstalls will never again be necessary if you create a Backup Image stored externally, using Win7 Backup & REstore center. By just booting from the INstaller and choosing Repair my Computer>Recover from an Image you can reimage your HDD (or a replacement) in 15 minutes flawlessly.
