The correct answer is B. BOOT .INI. BOOT.INI is the text-based configuration file on Windows NT-family dual-boot systems that controls the default operating system selection and timeout at startup.

Question

On your dual booting computer, you want to set Windows 98 as the default operating system at startup. In which file will you define this?

Options

ANTBOOTDD .SYS
BBOOT .INI
CNTDETECT .COM
DBOOTSECT .DOS

Explanation

BOOT.INI is the text-based configuration file on Windows NT-family dual-boot systems that controls the default operating system selection and timeout at startup.

Common mistakes.

A. NTBOOTDD.SYS is a SCSI adapter driver loaded during boot for SCSI disk access and has no role in defining the default operating system selection.
C. NTDETECT.COM is a hardware detection program that inventories system components during the boot sequence but does not store or control OS selection preferences.
D. BOOTSECT.DOS stores a copy of the original DOS/Windows 9x boot sector to allow chainloading, but the selection logic and default setting are governed by BOOT.INI, not this file.

Concept tested. BOOT.INI default OS configuration in dual-boot setup
