During boot, what does the bootloader do regarding OS selection?

• A. It directly loads applications after boot.
• B. It configures computer BIOS settings.
• C. It runs antivirus checks.
• D. It initiates the boot process and presents OS startup options to the user.

Answer: (D)

The bootloader’s job is to start the OS loading process and, if more than one operating system is installed, present a startup option for you to choose which one to boot. It runs after the firmware hands control to the system, locates the OS kernel, loads it into memory, and transfers control to the kernel so the OS can begin initializing. If there’s only one OS, it will typically boot it automatically after a short delay. This step is distinct from loading applications once the OS is up, configuring BIOS/UEFI settings, or running antivirus checks during boot.
