The Boot Menu is a menu accessible when a computer is first starting up. It can contain many different device options to boot to, including CD, DVD, USB flash drive, or hard drives. The Boot Menu allows a user to load up other operating systems or applications, even if the computer itself already has an operating system on it. Here is the list of possible keys you may have to press depending on your PC.
