What is the OS boot manager?
A boot loader, also called a boot manager, is a small program that places the operating system (OS) of a computer into memory.

What happens when Linux boot?
In simple terms, the BIOS loads and executes the Master Boot Record (MBR) boot loader. The MBR is sometimes on a USB stick or CD-ROM such as with a live installation of Linux. Once the boot loader program is detected, it’s then loaded into memory and the BIOS gives control of the system to it.
