I had a problem that my laptop (MSI-GP60) screen would only go up when connected to an external screen. so I tried to disable the other graphic card - Intel HD graphic 4600 throught Device Manager - Display Adapters. and after that the screen went black, I restarted and got that result:

As you can see windows is turning up but there is a problem with the graphic card.
