    Install Win 8.1 or Win10 fails

    I am using a Dell Inspiron. During an install (update) using a DVD, after a long time I get the error message

    Error oxC1900101 - 0x20017
    Operation failed in the SAFE_OS phase during BOOT operation


    when attempting to upgrade Win7 to win 8.1 after re-installing Win 7 from DVD or
    when attempting to upgrade Win8.1 to Win10 after re-installing Win8.1 from DVD

    Automatic recovery did not work and I cannot find any MS help for the above error!

    I have spent more than one day trying to resolve this problem.

    Please help.

    If you disk drive is encrypted try turning off encryption and try the upgrade again. If it is successful then turn encryption back on.
