The operating system is loaded through a bootstrapping process, more succinctly known as booting. A boot loader is a program whose task is to load a bigger program, such as the operating system. When you turn on a computer, its memory is usually uninitialized. Hence, there is nothing to run.

Where is the operating system loaded when a system is booting?
