Need help reinstalling Genuine XP Home over XP Pro RRS feed

  • Question

  • A friend gave me her old Dell computer which originally had XP Home on it.  She caught a virus and her son formatted the hard drive and put on his XP Pro version so now a message comes up saying "This copy of Windows is not genuine". 

    I would like to reinstall Windows XP Home.  The original product key is on a sticker on the side of the computer, however she did not get a Win XP Home CD with the computer.  I can borrow a Dell Win XP Home CD for another computer, but I am wondering if it will install okay when I put in the original product key. 

    Any suggestions??   Also if this idea will work, do I have to format the hard drive and how do I do that?   I assume that I cannot do a repair install since it will be going from Win XP Pro to Win XP Home.

    Thanks!

    First make sure all the data is backed up and offloaded from the computer.

    Insert the Dell OS Reinstallation CD and restart the computer.  Press f12 (IIRC) at startup to get a boot menu, then start the computer from the Dell CD.

    The Dell CD looks for special data in the Dell motherboard BIOS, and if it finds what it wants, the Dell CD will complete Windows XP setup without the need to enter a Product Key.

    The Dell OS Reinstallation CD only installs the OS.  Visit the computer's drivers download page by entering the Dell computer's Service tag number at http://support.dell.com.

  • Hi Dan,

    Thanks for responding.  I'm still a little confused.  Is it okay to use someone else's Dell OS CD??  If the CD looks for special data on the motherboard isn't it just going to find the product key for the Win XP Pro (not genuine) instead of the info for the original Win XP Home???   I would think that I would have to re-enter it in order to correct the problem.  Please advise.   Thanks.

  • Hello sillycat41,

    "Is it okay to use someone else's Dell OS CD??"

    As long as you are using a Dell OS Reinstallation CD on your Dell, and as long as you are using a Dell OS Reinstallation CD for an edition of Windows that matches the one on your computer's CoA, it's OK to use any authentic Dell OS Reinstallation CD.

    "If the CD looks for special data on the motherboard isn't it just going to find the product key for the Win XP Pro (not genuine) instead of the info for the original Win XP Home???   I would think that I would have to re-enter it in order to correct the problem.  Please advise."

    The CD looks for special data, but that data is not the Product Key.  The Dell OS Reinstallation CD has the Dell-specific deployment product key already programmed into the Setup program.  So a Dell CD for XP Home will have the Dell deployment product key for XP Home programmed into it.

    Because you cannot change from XP Pro to XP Home without a clean installation, you must perform a clean installation with the correct Dell CD.  You should check the Dell support website for specific step-by-step instructions on how to do this.  The clean installation process erases all user data on the hard disk drive, so be sure to backup and offload anything you do not want to lose before you start the clean installation.


    "Thanks."
