What is the role of a bootstrap loader?

The bootstrap loader plays a crucial role in the startup process of a computer system. Its primary function is to load the operating system into memory when the system is powered on or rebooted. During the bootstrap process, the bootstrap loader is activated by the computer's firmware. It locates the operating system stored on a disk or other storage device and loads it into the system's memory, making it ready for use.

Once the operating system is loaded, it can take over the control of the computer, allowing users to run applications and interact with the system. This process is essential because, without the bootstrap loader successfully loading the operating system, the computer would not be able to operate as it lacks the necessary software to manage hardware and execute user commands.

While other tasks such as executing user applications, managing system updates, and performing diagnostics are important functions of an operating system, they occur after the operating system has been successfully loaded into memory by the bootstrap loader. Therefore, the correct function of the bootstrap loader specifically pertains to the loading of the operating system itself.
