Windows 7 Reinstall

I getting ready to upgrade my mobo and cpu and am
currently running the Windows 7 Pro Upgrade that I installed over
Windows XP.

I want to do a clean install of Windows 7 after
replacing the mobo and cpu. Can you just boot from
the Windows 7 upgrade disk or do you have to
reinstall Windows XP first?

If you can boot from the Windows 7 upgrade disk
do you just update the current Windows 7 install
or do a custom installation and wipe out the previous Windows 7

I've already backed up all my files on an external hard drive.

Thanks for the help!

  1. Legally speaking, if the OS was an OEM version, then it stays with the original MB and CPU. You need a new copy.

    However, you should be able to just start from the Win 7 disc and only need the XP discc when prompted. Remember that MS is more picky about Win 7 and you'll probably have to jump thru hoops to revalidate the install
  2. No you can just install a fresh copy with your new set up I have done it a million times you might have to call the automated activation service but maybe not if so just say you have installed your copy on one machine.
  3. This was a Windows 7 upgrade that I installed over Windows XP.
    (Both are legitimate.)
    I want to change my mobo and cpu but will need to do a
    fresh install of Windows 7.

    Can you just boot from the Windows 7 upgrade?
    If so, do you just do the upgrade installation or
    do you have to do the "custom" install where you
    wipe out the previous Windows 7 upgrade install?
  4. Ah took me a while to understand what you were talking about. So you are changing the motherboard and cpu, but keeping the other components.

    You can try repair first, that should install the necessary drivers.

    If that doesn't work you will have to do a custom install.
  5. Should I delete all the old drivers first to get rid of the old
    mobo drivers and let the Windows 7 repair install replace
    all the drivers with the latest driver releases?

    Thanks for all your help!

    You can definitely boot from a windows 7 upgrade disc and do a clean install. As long as you have an existing operating system on your hard drive you will be fine.

    Windows 7 upgrade will not prompt you for any xp disc. It will look for an existing OS on the hard drive though.

    Don't worry about deleting any old drivers because if you plan on doing a clean install (which I recommend) it will wipe your drive of all old software and drivers basically giving you a fresh start.

    So back up all information you want to transfer over. Install your hardware, and then start with installing windows 7.

    - Boot from disc
    - Install OS
    - Enter product key
    - Install drivers/updates
    - Load back up backup material
