Bootloader: What it is, How it Works, and Why it Matters

A bootloader is a piece of software responsible for loading and initializing the operating system on a computer or mobile device. It's typically the first code that runs when a device is turned on, and its main function is to locate and load the operating system kernel into memory. The bootloader also performs hardware checks and initializes device drivers, enabling the operating system to communicate with the hardware. In addition, the bootloader provides a way for users to modify the device's firmware or install custom operating systems.
