I had the same problem and I turned off my laptop by holding the power button. I then held down the F2 button while I hit the power button, and released the power button while still holding onto the F2 key. Once the BIOS screen showed up ( a blue screen with the computers basic info) I navigated to the save and exit window, went down to "don't save and exit" option and hit enter (I didn't want to mess with any of my computers pre-assigned configurations). After that, my laptop went back to the ASUS loading page, turned black for a bit, then turned black with the loading circle visible, then went black again and then WORKED!! Sounds real finicky but I think it is just a matter of getting your computer out of that initial boot stage that solves the problem. Hope this helps!
