    windows error code oxc000021a


    Hello, hoping someone can help me out with this.

    I upgraded to W10 a few weeks ago from W7. All went well.

    Then 2 days ago i got the windows error code oxc000021a, and the computer wouldn't start. Couldn't get into safe mode, and repair didn't work either. Really annoying. I've had to reinstall windows 7. I can still see my windows 10 old install saved under windows.old.

    I don't have any option yet to re-upgrade to W10, despite putting all the updates on W7 again. What can I do to get W10 again and recover my data from windows.old?

    Any help greatly appreciated. Thanks!

    :)

    over.

    Help...

    Download Media Creation tool, Run it and Choose Upgrade this PC.

    This will upgrade your pc back to windows 10. You might want to delete windows.old Folder first.
