How to enter into the BIOS setup of a System[SONY VAIO]/ Boot Priority

Here in this video I have tried to demonstrate how to enter the BIOS setup of a Computer System. In this case I've used my Sony VAIO laptop running on Windows7 OS. In this system you just need to press the F2 key and you are in. In other systems you make try the common combo keys of F2, F10, Del... Hope it helped. Like the video if it was useful. Thanks!
