    When trying to oper Windows 11, I get the following error:

    The operating system couldn't be loaded because a critical system driver is missing or contains errors
    File: Windows\system32\drivers\wd\WdBoot.sys
    Codice di errore: Oxc0000076

    Can anyone help me?

    Hello,
    Thank you for reaching out.
    To attempt a resolution of this issue on the Windows 11 virtual machine, kindly perform the following actions:
    1. Start Parallels Desktop.
    2. Take a snapshot of your virtual machine by navigating to the Mac menu bar > Actions > Take Snapshot.
    3. Start the Virtual Machine.
    4. While the Virtual Machine is running, from the Top menu bar, click Actions > select Reset.
    5. Perform this action 3 times consecutively. This will boot your Windows into recovery mode.
    6. Once in recovery mode, Click on Troubleshoot > Advanced options > Startup settings > Restart > Press 4 to enter Safe mode

    Once in Safe Mode, to verify and restore the virtual machine system files' integrity, please perform the following steps:
    1. Open Command prompt as administrator (Windows search > Command prompt > Right-click > Run as administrator) and execute the following command:
    Dism /Online /Cleanup-Image /Restorehealth
    (kindly wait until the command is successfully completed)

    2 Then execute:
    sfc /scannow

    3. Then in the Command prompt, execute the following command:

    chkdsk C: /f /r

    5. The system may ask you to schedule a disk check for the next Windows restart. Type Y and press Enter.

    6. Next time you restart Windows, the disk check procedure will begin immediately.

    At the end of the disk check process, you will see the conclusion whether there were hard disk corrupted sectors that were successfully repaired or no errors were found.

    7. Reinstall Parallels Tools (Click on "Actions" menu on top of the Mac menu bar > Reinstall Parallels Tools)> Click on Restart the virtual machine.

    If the issue persists, please try the following steps:

    In the Command Prompt, run the following commands one by one:
    In Safe mode, Open command prompt and type the following:
    C:
    cd \Windows\System32\drivers\wd
    dir WdBoot.sys

    If the file exists, rename it by the command below (to disable it temporarily):

    ren WdBoot.sys WdBoot.sys.bak

    This prevents Windows from loading the faulty driver on next boot.

    Check if the issue persists.
