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:

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

I think you should be using Install.ESD (instead of ...wim). Microsoft hasn't used .wim in a while. So...

(1) Make sure of the letters on the Windows partition & the USB Installation drive...

(a) Plug in your Win 10 Installation USB flash drive. (Unplug all others.)

(b) Boot to it using your BIOS Boot Menu F-key.

Press & hold the F-key at the manufacturer's logo screen (or at the black screen slightly before). It should then present a menu that includes the Installation USB drive (showing the name of the drive's manufacturer). If two are present, choose the one that says "UEFI", if yours is a UEFI installation. Otherwise, choose the other.

(c) After it boots, click "Repair your computer" (instead of to install).
```
 This reboots to the external recovery environment of the Installation USB.
```
(d) Click "Troubleshoot > Advanced options > Command Prompt".
```
  This reboots again to its Command Prompt.
```
(e) Enter the following commands...

DiskPart <<<Start DiskPart

List Vol <<<List volumes & letters

Exit <<<Leave DiskPart

Identify the Windows partition by its label & size. The Installation USB drive should be FAT32 & the only Removable plugged in. Yours probably is labelled "ESD-USB". Are your letters C: & D:? Then enter...

DIR D:\Sources\Install.wim <<<Does Install.wim exist? (I think not.)

DIR D:\Sources\Install.esd <<<What about Install.esd? (That should exist.)

Here is mine...

(2) Next, we must discover the correct Index number to use in the Cleanup-Image command. If your Windows Edition is Home, the index likely is 1. But enter the following Get-WimInfo to find the correct index that goes with your Edition. Then, use that number at the end of the /Source parameter of the Cleanup-Image command...

DISM /Get-Wiminfo /Wimfile:D:\Sources\Install.esd

DISM /Image:C:\ /Cleanup-Image /RestoreHealth /Source:ESD:D:\Sources\install.esd:1 /ScratchDir:C:\Temp

That is using the Scratch directory you created earlier. If the command works, do the SFC again...

SFC /Scannow /Offbootdir=C:\ /Offwindir=C:\windows

I hope that will do it. Good luck. Here was my Get-Wiminfo...
