I have twice started with a clean install of win 7 and all drivers and MS updates. Then I upgraded to win 10 and the whole download and install appears to work without error. When it finally comes up and asks for the user to login, it accepts the password and when I finally press enter, it just sits there forever. If I press enter a few more times, it just reboots and gets hung at the same place. Can't do anything but reboot and get stuck over and over. Additional info: Win 7 was successfully activated There is no indication of an error anytime during the win 10 update. I am going to try everything one more time WITHOUT a password this time. Help!
