Okay, this may get a little long. I have an ASUS board with the AMI UEFI BiOS. It is a GUI ( Graphic User Interface ). With that, on the screen with all the devices, ali I need to do is to click on the device and drop it into the positon I want it it. When I have My boot order established I hit the Function key that will save the new settings and exit. In the Other BiOS, you had to click on the device to highlight it, then use the arrow keys to move it up or down to the position thast you wanted it in. Once you had it to what you wanted then you hit the function key that is designated for this ( maybe F5 ) and exit. If the screen looks like the one you posted before, then you have not changed your boot order and the Optical drive is in the 1st position. It will not automatically go to the second position, even if the Optical drive is disabled, it will just ask you to select a boot device as it is doing. If you do not save the settings before you exit and although you may have moved them, they will stay as they were before you reassigned, them.
