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.

I replaced the four files you listed (the ones loaded by DISM) from my work laptop which is 19045.2364 and here's what I got: X:\sources>x:\sources\dism /image:C:\ /cleanup-image /restorehealth /source:D:\sources\install.wim /scratchdir:C:\temp Deployment Image Servicing and Management tool Version: 10.0.19041.1949 Image Version: 10.0.19045.2364 [==========================100.0%==========================] Error: 0x800f081f The source files could not be found.

Still won't boot. I then tried: Running Startup Repair. It ran for a while, then rebooted; still no luck. Tried the options to uninstall latest update and latest feature; both failed. Did a dism /image:c:\ /get-packages /format:list. This displayed tons of updates, several related to 19041.2364. I tried uninstalling one using dism, but it didn't work. I have updated sfc and dism log files. I'll try to get them uploaded.

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

Anonymous

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.

The source files could not be found.

So it did run! Progress. Still won't boot. I then tried:

3. Did a dism /image:c:\ /get-packages /format:list. This displayed tons of updates, several related to 19041.2364. I tried uninstalling one using dism, but it didn't work.
I have updated sfc and dism log files. I'll try to get them uploaded.

2. What happens if you try the following:

and
- x:\windows\system32\dism /image:C:\ /cleanup-image /restorehealth /source:D:\sources\install.wim /scratchdir:C:\temp
