Is your hard drive connected to the motherboard?
It's asking you to select a drive then insert your OS.
I don't have any OS But I am not sure how to get into the BIOS
Well until you get an OS you won't be able to boot into windows....
When you first boot up it should show the ASRock logo and a message below it saying " press f_ to boot to bios" or something like that.
