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.

Good point, PCR... especially #1. There probably is no install.wim or the USB drive letter differs from what's used in the command-line.

Thank you. You did mention Install.esd too in your article. And I like using the external recovery environment of a Win 10 Installation USB drive because it comes with the latest version of the tools & files, if he will get it from the site... https://www.microsoft.com/en-us/software-download/windows10 Download Windows 10 - This is always the latest finalized Windows version, currently 22H2. Download MediaCreationTool22H2.exe & run it to make a Windows 10 Installation USB drive. Follow the instructions under " Using the tool to create installation media ". As it says, match it to the Language , & Architecture (x64/64-bit or x86/32-bit) of the computer on which it will be used. The Windows Edition to take is "Windows 10", which includes Home, Pro & others.

The OP is using the latest ISO, as he confirms on page 1. Here's what I have in mind: Option A is to use the right WIM/ESD path, as you said, and rerun DISM. Option B: Windows will probably load fine if some of the critical files (in the 250 missing files list I uploaded the list earlier) are restored. The CBS/CSI can be repaired once Windows loads correctly. Option C would be to uninstall the LCU package offline. This is the last option. BTW, DISM offline repair process logs the CSI/CBS events into DISM.log instead of CBS.log.

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.
