During the boot process, which component loads the operating system after hardware initialization?

• A. POST
• B. BIOS/UEFI
• C. The kernel loads the OS
• D. A bootloader loads the OS after hardware initialization

Answer: (D)

After hardware is initialized, a bootloader takes over to start the operating system. The bootloader’s job is to locate the OS image, load the kernel into memory, and transfer control to it. Once the kernel is running, it continues initializing the system and starts user-space operations. So the component that loads the OS after hardware initialization is the bootloader. The firmware (BIOS/UEFI) handles the initial hardware setup and then hands control to the bootloader, while the kernel itself is brought into memory by that bootloader and then takes over to finish booting.
