MacBook Pro retina Black lit Screen asking for Language

Was at University today finished my class and headed home. When I got back home I opened my MacBook Pro Retina expecting to see the log in screen.

However, it was a black lit screen which worried me. I restarted my Mac tried turning on in safe mode, resetting PRAM and SMC. This hasn't worked, it just eventually turns back into the black lit screen then a voice asks me to choose english as main language and press return. Please help!!!!!!!!!! Thanks
