  1. Windows 10 20H2 upgrade fails


    Hello all,

    I've been struggling over the past couple of days, trying to get a Dell Latitude E6540 laptop upgraded to W10 20H2, from 1909. I tried numerous solutions I've found on the 'net and nothing has worked, I'm hoping that someone here can help.


    Log files from the most recent upgrade failure can be found here:

    Windows 10 upgrade problem, no input accepted

    I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

    After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

    I will list some, or hopefully all, of the troubleshooting steps I have tried:
    • Move keyboard and mouse to different USB ports.
    • Try different keyboard or mouse.
    • Restart computer, repeatedly.
    • Google for related issues.
    • Update Bios, because why not.
    • Create boot media and revert to windows 7.
    The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

    Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

    Upgrade to 20H2 failed

    The laptop was offered the feature upgrade to Win 10 20H2. It is still running 1903. It had failed 1909, 2004 with this error 0x80004005 - 0x1000A,The installation failed in the DOWNLEVEL phase with an error during PREPARE_FIRST_BOOT operation.

    Since Microsoft does not like this laptop anymore I had done a chkdsk, a SFC / scannow and a disk error check from the properties tab. All errors fixed.

    I stopped MS secutity, firewall and the Avast security for the upgrade.

    Downloading and installing took some time and it looked as if the laptop was going through the motions. At the end it had just reverted to 1903 again.

    What else can I do short of a complete reset?

    Windows 10 fails to update


    When you finish testing the Avast suggestion, make sure that you restart your machine.

    Then if the issue persists, please return to the trouble shooting list in post# 89

    I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.
