Startup issues happen to most computers after they have been in use for a few years. The ideal fix in the case of Windows is to do a clean install of the OS. But often that is not possible because you do not want to upset the way your PC and all the software are configured. The only way out in that case is to try to use the Bootrec command and fix the problem.

In this article, we are going to understand: 

  • What is Bootrec.exe?
  • How to use Bootrec.exe?
  • What are the Bootrec commands? 


What is Booting? 

Most users have little clue about booting. Booting refers to pulling oneself up by the bootstraps.

  • When the computer is inactive (no power), turning it on activates BIOS, a tiny program stored on a chip. BIOS runs on its own battery.
  • BIOS signals to the CPU to wake up and provides basic data—how much storage, what type of SSD/HDD, RAM, USB, keyboard, mouse, tablet, mic, camera, and other PnP devices, and booting order.
  • The CPU does a self-test to check if everything is working. The monitor should display something at this stage.
  • The CPU now loads the OS based on boot records. The master boot records are located on the very first sectors of the hard drive. That is why the C partition always has to be the system drive.


What is Bootrec.exe? 

What is Bootrec.exe is a common question from our clients. We will tutor you, how to use Bootrec.exe.

It is a series of steps to ensure that the faulty master boot record is repaired.

Exe means an executable file. Bootrec is a series of commands that have to be run from the command line. 

This cannot happen from Search bar > CMD since the device is already in use. It has to happen between boot and complete loading of the OS. Most tools that target C drive like SFC Scan and antivirus scan work best at this stage when the PC is not completely awake but all components are working. 

To know what are the bootrec commands follow the tutorial below closely. 


How to use Bootrec.exe?

You cannot access the Bootrec tool from inside the OS.

It is present in the Windows install media which is either DVD or USB.

To use Bootrec first change the BIOS to boot from USB or DVD, press F10, and exit

1. Press any key to boot from USB

  • The first is Bootrec /fixmbr (It will clean the MBR and fix corruption)
  • The second is Bootrec /fixboot (if you upgraded Windows version and there is conflicting code) 
  • The third is Bootrec /scanos (to reveal the OS present. There maybe more than one)
  • The last is Bootrec /rebuildbcd (it builds completely new BCD) 
Bootrec /rebuildbcd


You can see the steps i) to iv) typed and executed through CMD

Does Bootrec Always Work?

Now you understand what is Bootrec.exe. But does it always work?

A sad fact is that Windows tools are the first line of defense and nothing more. Knowing all about how to use Bootrec.exe can only help to an extent. 

Tools such as ScanPST and ScanSFC and Bootrec often fall short of their intended use.

However, this gives rise to a larger problem if the device stops booting or boots slowly. Access to the hard disk and the valuable data contained therein becomes impossible.

The only solution is to use a robust data recovery tool, such as Stellar Data Recovery for Windows.
