Preparing automatic repair black screen afterwards stuck

Fixing this gaming PC for a friend. His computer gets stuck on the windows logo with the dotted spinning circle. In the past to fix this i've done a startup repair. But this time, the PC starts the Preparing Automatic Repair, then screen goes black, where normally it should be showing diagnosing your pc before loaded the Automatic Repair screen.

What should I attempt to try next?
