What is BOOT

1. Alternatively referred to as boot up, booting is the process of powering on a computer and getting into the operating system. During the boot process, the computer will perform a self-diagnostic, also known as a POST and load necessary drivers and programs that help the computer and devices communicate. 

If the computer cannot boot, you may receive a boot failure error, which indicates that the computer is not passing POST or a device in the computer such as the hard drive has failed.
