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.

iorate.sys matches what you have. Same hash. BTW, when I try to boot regularly now it gets to the window screen, then spins forever. The Caps Lock key on the keyboard also stops working implying the USBs are disconnected or something. I tried booting into safe mode and had basically the same thing happen.

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.

iorate.sys is the LowerFilters driver. If it's missing, Windows won't load.
