  1. Activation after reinstall, error 0x803F7001


    Hi,

    I recently had a hard drive failure so had to revert to my previous drive which did not have an OS installed. I was unable to make a USB boot to install Windows 10, so I had to use a friends Windows 7 CD to get my system up and running to install 10... after going through this process I have been unable to activate my copy of Windows 10 Pro as I had no product key for the Windows 7 install...

    My MSA has a copy of Windows 10 Pro assigned to it.

    How can I get my installation activated?! or do I need to do another fresh install in order to do this??

    Any help or assistance would be very much appreciated. Thanks for your time.

    :)

  3. Invalid partition table

    The error is 0x803F7001

    You must remember I had to format this machine to reinstall Windows after the original online upgrade failed. This means I didn’t have a version on the tin when reinstalling so now I have no key. Thing is, the reason I don’t have a key is a Microsoft
    issue so I need this machine activated asap.

    Activation after reinstall, error 0x803F7001

    AIUI, if your previous install had already been activated and said 'Windows is activated with a digital licence' or '...a digital licence linked to your Microsoft account' then you should just click 'I don't have one' when asked for a product key during a clean install. The activation servers should then automatically activate it based on the existing digital licence.

    This worked for me when I put a clean HDD into a machine previously activated for 1511. I wanted to test a clean install of 1607, it activated immediately. I have no Microsoft account, so this machine's licence was tied to its hardware (the disk is not factored in for licencing purposes).
     
  5. So I need to re-install using this option? I note that the first time I attempted to install it I had selected that option, as well as the automatic updates while installing - but after waiting nextly 24 hour for it to get above 0% of the "checking for updates" I decided this option would not be the right one for me, hence why I have installed it as a clean install and associated the install with my MSA, but am still unable to activate.
