    Update fails to install with error code 0x8007042b


    I'm trying to install the latest Dev channel update for Windows Insiders, and the update fails and rolls back each time.


    I've tried running the Update Troubleshooter to no avail.


    I've followed previous instructions to take a look a setuperr.log and here's what it says:

    BIOS error codes

    So I have motherboard with installed small LED screen, which presents BIOS error codes.

    Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

    Ex after installing sound card, the motherboard startup fails with the code 15.

    Example picture of code is here.
