    Unable to install 20H2 from USB or upgrade from Windows update


    I want to do a fresh install of my Acer laptop, but the Live USB of 20H2 v2 (2021-02-27 download), which I used to install the Desktop several weeks ago, stops the installation because it's missing a driver. Then I tried to update it with the offer on the Settings\Updates and this returns me to the same screen. Currently, it's Windows 10 Home v2004 build 19041.928 AMD Ryzen 3 3200U with Radeon Vega Mobile Gfx 8GB RAM

    :)

    Unable to install 20H2 from USB or upgrade from Windows update

    Thanks for the suggestion. Just before I was about to use the upgrade assistant, Windows update demanded a reboot. After reboot, the system was upgraded to 20H2, 24 hours after I clicked on the upgrade offer. System info indicates 20H2 but the update screen still offers to upgrade to 202H.

    Installing windows off of a USB stick

    Step By Step from vista:
    From admin cmd prompt

    1. diskpart
    1a. list disk
    2. select disk 1 (replace 1 with your usb drive)
    3. clean
    4. create partition primary
    5. select partition 1 (replace 1 with your usb drive)
    6. active
    7. format fs=fat32
    8. assign
    9. exit

    Copy Windows Vista's DVD ROM content to the Flash Drive

    xcopy d:\*.* /s/e/f e:\ (d being your vista cd and e being your usb stick)

    And that's it, boot off your usb disk

    Unable to install updates 20H2 and KB4568831. Updates are downloaded, installed, the installation reaches 100% and everything starts from the beginning, I've tried many installation methods, nothing helps.
