  1. Blue screen on boot after Windows Update


    The problem is that I get blue screen on boot, with the error code 0xC000021A. When the percentage on screen hits 100%, it instantly shuts down, and the next time I boot I either get the same error, or I get automatic repair which fails every time. The first time this happened was over a month ago, I think on Friday 11 June; the previous evening I installed a Windows update. The problem has come back several times, most recently being two days ago Friday 23 July again after installing a Windows update.In the beginning I sometimes managed to get rid of the problem for a while after using Sy

    Startup Blue Screen

    Hi Jon,

    Startup blue screen error(s) can occur if a problem causes your PC to shut down or restart unexpectedly. It could be due to the following:

    • Outdated device software drivers
    • Corrupted Windows update system files
    • Software/Security conflicts

    We would like to know some information:

    • Did you get any blue screen stop error codes?
    • Have you tried booting in Safe mode?

    We suggest that you check this
    article
    about troubleshooting blue screen errors and follow the troubleshooting steps provided there.

    We will wait for your response

    Blue screen and stop code

    Hi
    Jeferis,

    There are a lot of factors for this matter to occur. To isolate the issue, we have some questions for you:


    • What activity have you done to
      trigger the NTFS and FAT FILE SYS loop?

    • were there any error messages?

    • What troubleshooting steps have you done so far?

    It is possible that the
    Boot
    Sequence were corrupted by the previous activity which
    triggered the Blue Screen Error and the loop. We recommend that you perform these
    suggested troubleshooting
    and see if there are any changes:

    Startup Repair.


    To access the
    Startup Repair Screen, turn off the
    PC 3-4 times(force shutdown),
    while on the Blue screen Error. This will route you to the
    Startup repair screen:

    Advanced Boot Options > click Troubleshoot > Advanced options > Command Prompt

    and run the following command:

    Run SFC Scan:  

    SFC
    will
    scan
    and
    run
    an
    automatic repair
    to any
    corrupted system files
    that it will detect. We suggest that you perform it twice. To run an
    SFC scan, follow these steps:  


    • Run
      Command Prompt as Administrator.  

    • Type
      sfc /scannow
      and hit
      Enter.   

    Boot Record:

    This will fix the corruptions on
    boot records or boot
    sequence. To run this command, follow these steps:


    • Run
      Command Prompt as Administrator.

    • Type the following command:  

      • Bootrec /fixMBR  

      • Bootrec /fixBoot

      • Bootrec /rebuildBCD

    Update us on how it goes.

    Regards.
