boot loader
System initialization program
A boot loader is a small program that runs when a computer starts up, responsible for loading the operating system into memory.
It's the first software to execute after the hardware powers on, bridging the gap between raw machine startup and a functioning system.
Most users never interact with boot loaders unless dual-booting between operating systems or troubleshooting startup problems.
