BOOT

Boot

The process by which a computer is started up and its operating system kernel is loaded into RAM is called the boot, or bootstrap, process. The basic steps are the:

  1. Execute a hardware self-test.
  2. Look in a predefined place for the boot sector and load this code.
  3. Execute the boot sector program to load other programs.
  4. Execute these programs to load still other programs or to configure the operating environment.
  5. Repeat the previous step as often as dictated by the programs being loaded and by their initialization code.
