    BSOD Playing Rome 2, error code 0xc000000f, cng.sys missing or corrupt

    First off I am new to the Windows 10 forum so please let me know if I'm doing anything wrong, thanks!

    Ok now to my problem. I was playing Total War Rome 2 when my PC crashed and went right to the BSOD, saying that Microsoft was gathering information about my system, and it would restart when it was complete. I went away for about 2 hours and when I got back, it was still at the same stage. I powered down my PC and when it restarted I was at the Automatic Repair screen. There are several options, but none of them work. Even the advanced options like safe mode and straight up reinstalling windows do nothing. They all just make the screen black for a few seconds, the right back to a menu saying Automatic Repair has failed.

    I've tried several options via the command prompt since it's the only working option I have, but no dice. The initial Automatic Repair screen shows is this,"There was a problem booting your PC/Device. A file was found missing or corrupt. File: cng.sys Error code: 0xc000000f" The things I tried through the command prompt were guides I found through google searches. They pretty much all were commands relating to bcdedit. There is a log file located at E:\WINDOWS\System32\Logfiles\Srt\SrtTrails.txt. It reports an error due to the boot manager.

    Please tell me if there is anything I can provide to help, also please note that I can't access my PC so any "screenshots" will have to be from my phone. Thanks for any help you can provide.

    Hello and welcome to the TenForums

    As we can't get the log files from you it is going to be harder to trace the cause.

    From your description thecng.sys file is mentioned, this is a Windows system file so if you can get to the command prompt can you run the sfc /scannow command which will repair any system files. See if this helps.

    Another option is to try a recovery disk which you can make on another machine, see Windows 10 Recovery Tools - Bootable Rescue Disk
