Hi! @Frostbite63,

Did you make any software or hardware changes to the PC?

It looks like the system board needs tattooing.

Tattooing is taking information from a system and applying it discretely to the hardware to avoid licensing issues and Microsoft has a hand in its implementation.  If the Hard Drive DMI and Motherboard do not match up, it will not work correctly which is why they state to run the Motherboard tattoo process. 

However, you can try the following code and check if it helps.
