What is Windows Boot Manager in BIOS

The Windows Boot Manager, provided by Microsoft, is an application that sets up the boot environment on a device. It ensures that essential functions are available before the device fully starts up. The Boot Manager identifies the bootable device and loads the operating system into the computer's memory.

This process is made possible through the BIOS, which is responsible for initializing hardware components and providing boot instructions. The BIOS-based system starts with a power-on self-test to check for any hardware issues and then looks for a bootable device, like a hard drive. Once found, the Boot Manager reads the necessary instructions from the master boot record or boot sector to initiate the Windows operating system.
