Boot Loaders
Boot Loaders play an integral role in booting up any Linux-based system. When the system is switched on, it’s the Boot Loader that takes charge and loads the kernel of the OS into the system’s memory. The kernel then initializes the hardware components and loads necessary drivers, after which it starts the scheduler and executes the init process.
Typically, the two most commonly used boot loaders in Linux are LILO (Linux Loader) and GRUB (GRand Unified Bootloader). GRUB sets the standard for modern day Linux booting, providing rich features like a graphical interface, scripting, and debugging capabilities. LILO, on the other hand, is older and does not have as many features, but runs on a broader range of hardware platforms.
