Hi, can anyone please explain why in this site bellow it says that:
"If you are attempting to clean install with a Windows XP Home or Pro Upgrade CD, you will see this screen, which requires you to insert your previous Windows CD in order to verify that you qualify for the Upgrade version. Curiously, it says that you can use CDs from Windows NT 3.51 and Windows 95 in addition to those from 98, 98 SE, Millennium, or 2000, though these products cannot be upgraded to XP. Once you’ve proven that you qualify, hit ENTER to continue." http://www.winsupersite.com/showcase/windowsxp_sg_clean.asp
So does this mean that if i want to update my windows from 2000 to Xp i will need a previous windows CD ? I read somewhere else that only a Windows Xp CD will do, thats why i am really confused…
