Loading XP pro over XP home version

By coneakai ·
I have a Compaq computer with Windows XP Home. I bought Windows XP Pro OEM by mistake and it won't load. Microsoft's advice was to comtact Compaq. Compaq's help was to F-disk the main drive and fresh load the XP Pro. There has got to be another way to install Pro without a complete drive wipe and reload. Isn't it?

Every time I try to load XP I get the message that the system I'm trying to load is older than the current operating system and the install stops.

How old is the computer? You might try flashing the bios. What is the model? You can also try loading XP Pro when you have the Home GUI running. When do you get this error message? Is it when you boot to the XP Pro cd? Perhaps you can use Partition Magic to create another partition and put XP Pro on the new one to see if that works. Then you will at least know if it is a hardware or software problem. Let me know.

yeah Windows Home SP2 won't let you load up XP Pro SP1 over it.

Try uninstalling SP2 from Add/Remove programs if you don't see it listed, look at the top center portion of the add/remove programs window and you'll see a check box for show updates. Check the box.

then try loading up Windows XP Pro SP1 over Home SP1.

the other thing is try getting whatever vendor who sold you XP Pro and return it. Get the retail product with SP2.

I had this experiance once before. Just continue with the installation. Insert the xp pro cd into the drive. re-partition the drive. then install, unless your trying to go from home edition to pro edition without loosing data. Trying to go from an new version to an old doesn't act like an upgrade.

If your Pro OEM is SP 1 or 0, you can make a slipstreamed Cd and add SP2 using nLite, quite painless. You can download it at: http://www.nliteos.com/
