What part of the boot process checks the hardware?


The boot process of a computer goes through many processes before it is ready for user interaction. What part of this boot process performs a comprehensive check of the computer’s hardware?

A) POST

B) The MBR load

C) The NT loader

D) NTBOOTDD.SYS driver load


The answer: A) POST

The answers to this question were kept relatively cryptic to test your knowledge of the boot process. If you know what is referenced in each of those answers, then you’re very familiar with the boot process! The power on self test (POST) is the first thing a computer does when it starts, and it performs a relatively thorough check of the hardware and attached components.

The incorrect answers:

B) The MBR load
The master boot record is most often found on the first sector of the first hard drive in a computer. Among other things, the MBR contains a partition table that identifies where the bootable partition is on a computer.

C) The NT loader
The Windows NT loader (NTLDR) is an important boot loader for the Windows OS. NTLDR is responsible for loading the files necessary to start the Windows OS.

D) NTBOOTDD.SYS driver load
The NTBOOTDD.SYS driver is loaded by the NT loader when a SCSI drive subsystem is required during the boot process.

When most people start Windows, they see a graphical “splash” screen and a moving status bar. Under the surface, Windows is initializing hardware, loading configuration files, and handing off control to the Windows kernel. In this video, we’ll look at this process in-depth and review some utilities that can assist with troubleshooting the Windows startup process.
