As far as the cold reboot, I think John just means restarting and, during startup you should see the option for win 7. I don't know because all of my win 10s are clean installs. You can make a password recovery disk from another computer do you have a WIN PE. My problem is I have too many. Off the top of my head, Windows Geek is good. I will look at my password discs tomorrow. I don't think all is lost.
