I'm posting from my other PC....
I have 2 cores checked by default in msconfig, that's the first thing I do after an install, but it has to do with how many cores it uses during boot only, not later use in the system.
I checked "DETECT HAL" , and now my PC starts with a black screen only.
I can only see the watermark "For testing purposes only" but not anything else. Dead. Mouse and all respond, but I'm actually locked out. I'll enter repair mode to change bcdedit to "detecthal no" if I can access it and post back. This didn't fix it
Locked me out. wtf?
