Archived from groups: microsoft.public.windowsxp.help_and_support (More info?)

Any legal PreInstalled version of XP must have a way to Recover the system. Determine what you have purchased for that.

If you have the regular setup cd:

If you run an XP "Upgrade"setup, from the original, or "Gold" version of the setup CD, and you have SP2 installed, it might go into
a setup loop, and you could lose your install. Uninstall SP2, BEFORE you Upgrade setup from CD (that lacks sp2 on it.)
