Bootstrap loader locates the kernel, loads it into main memory and starts its execution.
|
|
A simple bootstrap loader fetches a more complex boot program from disk, which in turn loads the kernel in all system.

Hardware know where the operating system resides and how to load it.

Detailed explanation-1: -The correct answer is option 1. Key PointsBooting is a startup sequence that starts the operating system of a computer when it is turned on. A boot sequence is the initial set of operations that the computer performs when it is switched on.
Detailed explanation-2: -Six steps of the booting process are BIOS and Setup Program, The Power-On-Self-Test (POST), The Operating system Loads, System Configuration, System Utility Loads and Users Authentication.
Detailed explanation-3: -The entire operating system depends on the bootstrap program to work correctly as it loads the operating system. In the above image, the bootstrap program is a part of ROM which is the non-volatile memory. The operating system is loaded into the RAM by the bootstrap program after the start of the computer system.
Detailed explanation-4: -In computing, booting is the process of starting a computer as initiated via hardware such as a button or by a software command. After it is switched on, a computer’s central processing unit (CPU) has no software in its main memory, so some process must load software into memory before it can be executed.
Detailed explanation-5: -A Bootstrap Loader (BSL) is a small program which can be activated immediately after a microcontroller has been powered up, in order to load and execute another program in a well defined manner.
