Which of the following statements about the NTDETECT.COM file is true? Each correct answer represents a complete solution. Choose three.

NTDETECT.COM scans the system during boot to collect hardware information such as CPU type, bus type, and installed devices, then passes this data to NTLDR for proper OS initialization. This hardware detection role is its primary function in the Windows NT/2000 startup sequence.

NTDETECT.COM is a mandatory startup file in Windows NT/2000, invoked by NTLDR immediately after the boot sector hands off control. Without it, the OS cannot complete the hardware initialization phase and will fail to boot.

NTDETECT.COM must be placed in the root directory of the system partition (typically C:\) so that NTLDR can locate and execute it. Its placement is fixed and required for the boot process to succeed.

Dual-boot configuration is controlled by the BOOT.INI file in conjunction with NTLDR, which presents the OS selection menu. NTDETECT.COM only performs hardware detection and plays no role in selecting or switching between operating systems.
