Windows 10 can't boot - Critical system driver is missing or contains errors

Hi,

The file in question is: \Windows\system32\drivers\VmsProxyHNic.sys, error 0xc000007b

The file is there. I'm using an SSD. From a bootable USB I've tried:

  1. chkdsk C: No errors reported.
  2. Startup Repair - Says it couldn't repair my PC.
  3. Uninstall latest feature - Says it can't
  4. Restore from a prior point - There are none
  5. Copying the file in question to a .bak, then deleting the original and copying it back - No effect
  6. Can't boot into Safe Mode

Any other things I can try? I'd like to get this to boot again so I can at least see what programs I have installed.

Thanks.

After running that command, have you checked the CBS log to see which components are missing?

And regarding the failed repair installation, you can check setupact.log and setuperr.log in the Panther folder. Or download SetupDiag from this link and run it. The tool collects the setup logs and saves them into a zip file named Logs.zip on your desktop.

(1) I still say to try the repair-install again. It must be run from a Normal Boot (not Safe Mode), if you can get back there. Do the clean boot first, which unfortunately will require a 2nd boot to Normal Mode before you can do the repair-install. (But possibly the clean boot can be set up in Safe Mode, then boot to Normal Mode.). Definitely, wear a neckless of garlic this time. But a repair-install is the thing.

(2) Had you made a system image after that successful boot to Normal Mode, you'd have locked the goodness in. Hopefully, you can get back there easily, though. Restore Points aren't as powerful. For one thing, a repair-install wipes them out.

    One thing I noticed is the latest ISO I can find to download and burn to the USB is 10.0.19041.2006. My dead PC I believe is at 10.0.19045.2364; could that make a difference?

    Hi,

    If you've downloaded the ISO from Microsoft, the latest available version (as of this writing) would be 19045.2006. So, that's not the issue.

    (DISM might report the ISO version incorrectly. There is a catch. Check out the section "Windows 10 ISO Version and build number are reported incorrectly" in this article.)

    Can you upload the SFC log?

    I downloaded the latest consumer Win 10 22H2 from December off my Visual Studio subscription.

    Here's what I ran:

    c:\Windows>dism /Image:c:\ /Cleanup-Image /RestoreHealth /Source:d:\sources\install.wim /ScratchDir=c:\temp

    Deployment Image Servicing and Management tool

    Version: 10.0.19041.844

    Error: 193

    An error occurred while attempting to start the servicing process for the image located at c:.

    For more information, review the log file.

    The DISM log file can be found at X:\windows\Logs\DISM\dism.log

    c:\Windows>

    I don't see a way to attach files here; how can I get you the logs? My company blocks access to things like dropbox. The dism log is 96KB and the sfc log is over 3 MB.
