In NFTS architecture, which component loads the operating system after the boot sector?

• A. Ntldr
• B. Boot Sector
• C. Master Boot Record
• D. Operating System

Answer: (A)

NTLDR (Windows NT Loader) is the component that loads the operating system after the boot sector. In the Windows NT boot sequence, the Master Boot Record runs first to locate the active partition and hand control to its boot sector. That boot sector then loads NTLDR, which in turn loads the Windows kernel (ntoskrnl.exe) and essential drivers, completing the boot process. The boot sector doesn’t load the OS directly; it simply transfers control to NTLDR. The Master Boot Record’s job is to start this chain by pointing to the boot sector, not to load the OS, and the OS label isn’t a loader.
