Operating Systems: Start Menu file(s)

Which file displays the startup menu for a computer running Windows XP or Windows 2000?
1. Ntdetect.com
2. NTLDR
3. >>Ntoskrnl.exe
4. Bootsect.dos

Explanation : NTLDR is the file that displays the startup menu for a computer running Windows XP or Windows 2000. NTLDR reads the startup menu from the Boot.ini file and presents the menu. After the user makes a selection from the menu, NTLDR in turn loads Ntsokrnl.exe, Hal.dll, and required boot-start device drivers.

Bootsect.dos is not the file that displays the startup menu for a computer running Windows XP or Windows 2000. Bootsect.dos contains information about the boot sector that was on the hard disk before you installed Windows XP or Windows 2000 and is used to support multi-boot configurations.

Ntdetect.com is not the file that displays the startup menu for a computer running Windows XP or Windows 2000, though it is a critical part of the startup process. Ntdetect.com queries the computer for basic device and configuration information during startup.

Ntoskrnl.exe is not the file that displays the startup menu for a computer running Windows XP or Windows 2000. It instead contains the majority of the Windows operating system instructions. Ntoskrnl.exe is loaded after the user makes a selection from the startup menu.
