Definition: Booting a computer (out of the window) is something we're all tempted to do from time to time, but boot is just short for bootstrap. When a computer is powered on, it starts executing an application in its ROM.
This is called a Boot Program and usually you'll see lots of system messages before the Operating System starts loading. Nowadays the whole process from power on until being ready to use is called the Boot Process.
