To get to the BIOS. As your pc boots up, there will be a message to hit DEL key (possibly another) this opens the BIOS & you can check the boot devices. using the arrow & tabs keys on your keyboard.
But if you don't know this, do not try it. Get help from someone who knows what they are doing.
A thank you would be nice, if I have helped.
