gain, my Win 10 won't start....why does this keep happening? I have dual OS, lucky for me. A few months ago it won't start but then i got an error and corrected it and got it to start again. I forgot what the error was. Now, it stopped again but this time with no error. I used the Media tool and chose repair and it goes through its usual diagnostic mode and eventually says it cannot be repaired. I tried reset and the same situation...no help at all. I made sure that i disconnected my win 7, which i am using now writing this post, and both OS are on separate hd's. In fact Win 10 was installed on a less than one year old SSD. I did see the option to reinstall, but hesitated. If it does reinstall, at what stage would i get? Would i have to go through the constant updates again, which in my opinion are the cause of this loop of Win 10 getting a 'stroke' now and then or maybe Microsoft set it up this way so you can buy their 'free' win 10 system.
