Windows 10: Computer boots to BSOD, error 0xC000021A

I have a bootable USB with Windows 10, and another hard-drive plugged in running Windows 7. I have used the W7 boot to save my personal files which is lucky.

What I have tried:
- Boot to safe mode, disable driver signature
- Bootable USB -> "sfc /scannow /offbootdir=c:\ /offwindir=g:\windows" returns "Microsoft Resource Protection could not perform the requested operation"
- Registry replaced with backups

The SSD seems 'healthy'. Screenshot. CHKDSK passed but "failed to transfer log messages status 50". Are there logs I can locate manually on the troublesome drive and upload?

Any help would be appreciated, let me know if I can provide more information.

:)

What is the K partition?

How much free space does each partition have? Not enough can cause quite some issues, at least 10-15% free space is recommended.

 

Open administrative command prompt and run the following commands:
