Just installed build 14267. Everything seemed to go properly but when starting up I have a problem. I am using a Toshiba Satellite P75-A7200. Intel i7 with 8Gb ram. This is the third upgrade I have tried and with the other 2 I did not have a problem. When I start it goes to my Toshiba screen and stays there. I have to manually push the power button to get it to turn off. I then push the power button again and when it starts up it starts properly. When I get it started and try a restart everything works properly. It is only on initial startup after a shutdown. Anyone else having this problem.
