Boot Manager
A Boot Manager is a software program that is responsible for the management of the booting process of the computer. It is primarily responsible for selecting the Operating System to be loaded from multiple available options. Further, it also loads the Bootloader to perform the actual loading of the Operating System. Boot Manager is the program that manages the available “bootable” Operating Systems. In a multi-boot system, Boot Manager is the program that runs at the very first in the booting process. It allows us to select the operating system to be loaded from the available systems on the machine. If you have ever installed more than one operating system on your machine you may be getting grip on this topic. The task of the Boot Manager is to ask users which Operating System they want to load into the machine or choose the default if not selected specifically. You may also recollect that timer which when runs out of time, automatically selects the default Operating System. Once the “to-be-loaded” Operating System is selected, Boot Manager loads the Boot Loader and passes control to it. A Boot Manager does not load Operating System directly on its own. This is done by Boot Loader.
Some examples of Boot Managers are:
- The BIOS boot manager
- UEFI (Unified Extensible Firmware Interface) boot manager
- GRub(GRand Unified Bootloader) It is both Boot Loader and Boot Manager and is popularly used for Linux – based systems.
