Question BSOD after Windows update

[RasTaszi]

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.

---

x:\windows\system32>bcdedit /export c:\bcdbackup
x:\windows\system32>attrib c:\boot\bcd -h -r -s
Path not found - C:\boot

---

c:\windows\system32>bootrec /fixmbr
c:\windows\system32>bootrec /fixboot
Access is denied.
c:\windows\system32>bootsect /nt60 sys
c:\windows\system32>bootrec /fixboot
c:\windows\system32>attrib c:\boot\bcd -h -r -s
Path not found - C:\boot
c:\windows\system32>diskpart
DISKPART> list disk
DISKPART> select disk 0
DISKPART> list volume
DISKPART> select vol x (x = the FAT32 volume with ~100 MB size)
DISKPART> assign letter=v:
DISKPART> format fs=fat32 override
DISKPART> exit
c:\windows\system32>v:
v:\>bcdboot c:\windows /s v: /f UEFI

->
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.

You probably need to start from scratch

On another PC, download the Windows 10 media creation tool and use it to make a win 10 installer on USB

How to copy info off C drive you don't want to lose:

• on screen after languages, choose repair this pc, not install.
  
• choose troubleshoot
  
• choose advanced
  
• choose command prompt
  
• type notepad and press enter
  
• in notepad, select file>open
  
• Use file explorer to copy any files you need to save to USB or another hdd
  

Once you have everything you want to save, do a clean install - follow this guide: https://forums.tomshardware.com/faq/how-to-do-a-clean-installation-of-windows-10.3170366/
