Changing the boot order of the "bookable" devices on your computer like your hard drive,optical drive, USB flash drive,etc is very easy.The BIOS setup utility is where you change boot order settings.
Turn on or restart your computer and watch for a message during the POST about a particular key, usually Del, F2,F10,F12,Esc,etc.
, that you'll need to press to ...enter SETUP. Press this key as soon as you see the message.
