To get into BIOS or to recovery options, just shut down the PC the way you usually would. Then, press the Assist button to start the PC, not the power button. This will take you to a screen which I have attached below. From this screen, you can now press F2 to get to BIOS, or, since this screen also has mouse function (& touch function, if you happen to have a model equipped with a touch screen) you can click or touch your choice to boot into it. But you can only get to this screen when starting the PC with the Assist button.
