Key Points
- The first instructor of the bootstrap loader program of an operating system is stored in BIOS(Basic Input/Output System).
- The bootstrap loader is a programme that resides on the EPROM, ROM or other non-volatile memory of the machine.
- It is executed by the processor automatically when the device is turned on. To continue installing the computer's operating system, the bootstrap loader reads the boot sector of the hard drives.
- The bootstrap loader first conducts the power-on self-test, also referred to as POST, when the machine is switched on or restarted.
- The bootstrap loader loads the operating system for the machine into memory if the POST is successful and no problems are found.
- It is then possible for the machine to access, load, and operate the operating system.
- In computers that have an EFI (Extensible Firmware Interface), the bootstrap loader has been replaced and is now part of the EFI BIOS.
