Fixing an Unbootable Windows 11 OS


One thing you can do is mount the D: drive's SYSTEM registry hive, and check if the Service was actually removed. I don't have a PC with the Intel CPS feature, so I'm going by a 3rd-party site's ZIP copy of the extracted files.

reg load HKLM\TEMP D:\Windows\System32\config\SYSTEM
regedit

Now search under HKLM\TEMP\SYSTEM\ControlSet001\Services. Look for "INTCCoSvc". If it's there, delete that whole subkey.

Exit regedit
reg unload HKLM\TEMP

I removed the whole subkey and the DriverEntry failed 0xc0020035 error no longer appears!

The system however still does not boot........ So I'm now I'm a bit out of ideas.

I'm currently going through the Microsoft Debugging help articles to hopefully find a way to determine what's going wrong in the kernel.
