As a good point of reference, you can find a chart at
http://www.microsoft.com/windowsxp/home/upgrading/matrix.mspx that shows
what prior products are eligible for the upgrade (it lists both XP and
Home Editions)

> As for purchasing, get the upgrade, rather than the full version. And I

> you will get a full, clean install, as long as you have a prior version of
> Windows something on CD. You will be asked to insert the CD at one point in
> the installation process, and everything will continue normally after it's
> checked. It's the only way I would install an OS, as installing over a
> previous version introduces problems.
> You do not need a boot disk, all you have to do is set your BIOS to boot
> from CD first, insert the CD, and let the installation begin. All the
> appropriate files will be copied (installed) to your new, pristine hard
> drive.
> Good luck.
