Hi Andrea,
I was facing the same problem and I also posted this problem on some forums to get online solutions.But, They can't give exact solutions to my problem.some suggested check your disk whether the disk is okay or not, one of them said to clear your cache.
At last, I have to contact Windows customer support and they guided me.I would suggest you contact them without wasting your time here and there.
