BSOD after Windows update

Hello,

I tried to install some updates for Win10, my PC restarted as usual, then I got hit with a BSOD stop code: bad system config info.

What I did afterwards:

Recovery environment -> Advanced options:
Startup repair: error
Uninstall recent updates: error
System restore: succeeded but didn't solve the problem

Command prompt:

c:\windows\system32\config>md backup
c:\windows\system32\config>copy *.* backup
c:\windows\system32\config>cd regback
c:\windows\system32\config\regback>copy *.* ..
The system cannot find the file specified.

->
BSOD stop code: critical process died
File: \BCD
Error code: 0xc0000098

Restarted PC ->
Critical process died
Error code: 0xc0000001

I don't know what to do, please help.
