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.

    Ok. We're making progress. Now, we need the latest CBS log. Fixing the error 0x800f081f should resolve all other issues. I think we don't need to bother about the SFC report now.

    Pls check these locations:

    C:\windows\Logs\CBS\

    X:\windows\Logs\CBS\

    Pls upload *all* files in those folders.

    Also upload the output of this command redirected to "c:\packages.txt":

    • dism /image:c:\ /get-packages /format:list >c:\packages.txt

    No need for the DISM log, as the servicing issue has been resolved. It's a CBS problem.

    I looked at the SFC log and tried copying over files from my work laptop and re-ran SFC to no avail (I renamed the existing files to .old). I'm still getting errors like:
