  1. Cannot boot. Is error 0xc000021a unsolvable?


    Hi

    I upgraded from Windows 7 to Windows 10 and it was working fine for a few days but now whenever I try to boot it up I get BSOD with error code .

    I've tried the following 'fixes':

    System restore --- Runs for a few minutes and then says "Could not restore your computer. No changes were made"

    Clicking on any of the advanced startup options --- BSOD

    Reinstalling windows 10 with a usb --- Results in it going into circles with this messagea "The computer started using the Windows installation media. Remove the installation medial and restart your computer so that Windows starts normally. Then, insert the installation media and restart the upgrade. [Do not select iCustom [advanced]I to perform an upgrade. iCustom [advanced]I installs a new copy of Windows and deletes your programs and settings.)"

    I've taken the usb out and restarted the computer several times, even called Microsoft Technical Support. They had no idea what to do.

    I used to be able to access the command prompt and I tried everything suggested in this article here NeoSmart Knowledgebase. The reason I say "used to" is because things recently got alot worse when I changed the boot order and now it just turns black after the bios screen. I've tried to restore the BIOS setup to default settings and I also tried everything suggested in this article 3 Ways to Reset Your BIOS - wikiHow but nothing works.

    To recap, it started out as an unsolvable BSOD with error code and now after I changed the boot order it just turns pitch black.

    :)

    Windows 10 doesn't boot after auto update

    So auto update ran on shutdown last night, but today I cannot boot (error message 0xc000021a).

    Have tried booting in safe mode, restoring from previous points, system resets. But all of these options are resulting in failure (0x80070002).

    Is there anything left to save my poor PC?
