~The required operating system can be stored on different media - usually Harddrive, CD, DVD or USB. This media is called the boot device. The BIOS will load the first operating system it finds. If this is not the desired one change the boot device order. It can be set by entering BIOS settings - usually a specific key is held down on power-on/reboot. To find out which key is pressed see [[TableOfBIOSKeys Table of Keys for BIOS setup]].

?What have I forgotten, Ah! Ha! nothing, lets go outside.
The BIOS checks motherboard, memory, drives i.e. Floppy, Hard drive, CDROMs etc, if it finds the essentials it gives a happy beep and moves on looking for a boot program, if it finds something amiss it signals it's displeasure with a series of beeps in a code that, if you know the sequences, will tell you what is most likely wrong or missing.
==Boot Device==
The required operating system can be stored on different media - usually Harddrive, CD, DVD or USB. This media is called the boot device. The BIOS will load the first operating system it finds. If this is not the desired one the boot device order will need changing. It can be set by entering BIOS settings - usually a specific key is held down on power-on/reboot. To find out which key is pressed see [[TableOfBIOSKeys Table of Keys for BIOS setup]].
