Charles I think I got same problem. I have a lenova and when I was asked everyday by MS to upgrade to windows 10 I refused. I was very happy with my pre-installed win 7 gome premium. One day it started downloading windows 10 without my knowledge or I missed it but I couldnt stop it. It began installing after the dowenload and I had to sit helplessy and watch . It got to 95% finished and stopped with an error, the only thing is it didnt re-install my pre-installed windows 7. So I cant system recover or do much of anything on what I guess is what was left of puter without windows. I I purchased the recover windows disk but it is not helping one bit and am asking for refund. Microsoft says its a lenova issue and lenovo says MS sis responsible. I really had high hopes when I read about thewindow recovery disk I just purchased but I am again heart broke over my computer.
