BSOD reboot loop "CRITICAL SERVICE FAILED"
Hi there,
I am in an unpleasant situation and I hope you can help me.
First, I appreciate you need the correct information to diagnose - my system does not boot up anymore, not even in safe more, so I am unable to run the log collector app you require.
This is what happened: I was diagnosing another PC which had issues with Windows Update. I followed a tutorial and deleted the content of the CatRoot2 folder but I unintentionally deleted the content of the PC I was remoting from instead! (yes I know, don't say anything!)
In fact, I may have unintentionally deleted the CatRoot folder instead.
PC was still fine but I was unable to run mmc.exe (to change partitions). I tracked the problem down to the a digital signature in the CatRoot folder I tampered with so I decided to apply a System Restore.
I rebooted and that was the last time I saw Windows up and running.
The system is in a constant BSOD loop. Error is "Critical Service Failed". It does not show a STOP code.
I tried the following:
- Safe mode - ends with stop 0xc000021a
- Disable driver signature enforcement - the boot proceeds a bit more but then ends up with a stop code 0xc000021a
- chkdsk
- sfc /scannow
- automatic startup repair
- Apply other restore points (they all failed and eventually they all disappeared?)
- Run DISM via command prompt. I get a "the component store is repairable" but it doesn't like my source apparently.
- Tried boot logging but I cannot find the log file afterwards...
I appreciate that in these cases a reinstall is the best solution but I really would like to resuscitate the system - I'd like to recover my apps for now. I'm ok if this is not the best/fastest solution.
I also understand that to run a 'repair install' I need a working Windows installation.
I am not sure I can find the dump file, I found the attached which has today's date. I managed to open it with a dump file analyzer even though it has a TMP extension.
My system (apologies if not too detailed, I would need to access Windows to check!):
Computer name: should be ENTERPRISE
Windows version: Windows 10 , 1803
Windows dir: C:\WINDOWS
Hardware: MSI P67A G65 MB
CPU: intel 2600K
RAM: 8GB Crucial
I've always been so impressed by this forum - you have all my trust guys! :)
Please do let me know what you require from the system and I'll try to grab that.
Thank you!
