So i am trying to disable secure boot, i have watched a lot of videos. But my screen does not look like the one they have. I am running on windows 8.1 using an Asus i7-4790S 64 bit. When i try to disable secure boot, it is grayed out and you cannot change it. There is no supervisor password to set, only an administrative and user password. I have made/installed both of those passwords and still am unable to change it. Here are some screenshots of the settings on those screens i hope you can help. http://imgur.com/a/QzYBW (sorry i posted a link but the picture posting from the options did not work correctly.)
