    Stop code 0xc000021a BSOD

    Hi,

    The blue screen with the stop code 0xc000021a error that you've encountered can be triggered due to corrupted or missing registry files. To effectively assist you with your concern, we suggest that you boot your device in Safe Mode trough the Windows Recovery
    Environment. Here are the steps on how to trigger Safe Mode:

    • Turn on your computer.
    • When the Windows logo appear, unplug the power source of your computer.
    • Perform this step three times. On the fourth time, wait for the Windows Recovery Environment (WinRE) to appear.
    • On the Choose an option screen, select Troubleshoot
      > Advanced options > Startup Settings and click
      Restart.
    • Once your computer restarts, you will see a list of options. Press the
      F4       key to start your computer in Safe Mode.

    Once you're done, wait for your device to turn on and check if you encounter the same issue.

    Feel free to post back if you encounter any challenges along the process.

    Windws error "stop code: 0xc000021a after reboot

    In preperation to install latest version of office pro I removed office 2010. The system required a reboot to complete the operation, however, it failed with the error message stop code 0xc000021a. I can boot to a command prompt but that is all. I have
    tried dism.exe with sveral options listed in community search but this also fails.

    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.
