A Master Boot Record corruption or damage can occur due to factors such as virus infection, an installed third-party partitioning software, and so on. This could lead you to receive such error messages to indicate that your MBR is corrupt or there is an error occurring while loading your Operating System or an invalid partition table. Using the steps in this article for each Operating System, you will be able to fix and restore MBR on your Windows once again. This will enable you to boot your system properly without any error message showing. Before you dive into the solutions for restoring MBR on Windows, you can recover all your data from your system with the use of the tool that will be introduced to you: The Recovery Data Recovery app.
The acronym MBR stands for Master Boot Record. It is also called the master partition table or the partition sector. The MBR is the first boot sector or region of your hard disk that holds necessary information about your hard drive's partitions. This information shows how and where an OS (Operating System) is situated so that it can be loaded into the main storage of the computer or its RAM (Random Access Memory). The MBR is a vital part of the startup system of your PC. It is normally created upon the first installation of your Windows on the first partition created by you. It makes up your hard disk's first 512 bytes. Learn more about what is MBR.
If your Windows' Master Boot Record is corrupted or damaged, it simply means your computer won't function. There are some other boot errors you may encounter when your MBR is damaged; they are indicated by error messages including:
In a nutshell, the MBR is a vital part of your system booting. This means that if it suffers from one corruption or damage or the other, then it will prevent your system from booting.
To restore your Windows MBR, you will need to utilize a command prompt to run the command "bootrec.exe". The steps for achieving this vary for different Windows versions; these are divided as follows:
Before you can restore the MBR in Windows 8, 8.1, 10, or 11, the original Windows installation DVD is needed. Once you have this, proceed with the instructions below:
To rebuild MBR in Windows 7 using Command Prompt, you need the original installation DVD of your Windows 7 to boot.
If this set of commands doesn't fix the problem, you can use the second method as applied to Windows 7. This is where you export and erase the BCD store while using the "RebuildBCD" command to do the rebuilding or fixing of the MBR.
This should be your trump card. Your files are more important than anything else, so this is the point where you utilize a data recovery software to get your files back. And you're in luck because there's a great tool out there that fits the bill.
Recoverit Data Recovery is an excellent data recovery software that has been praised and patronized the world over for its efficiency. Its user-friendliness belies just how powerful it is, so if you lost your files via formatting, accidental deletion, virus attack, and, of course, corrupt MBR, Recoverit is what you need to rectify the problem and get your files back. Just follow the steps below.
Step 1 – Create Bootable Media
First thing's first: You'll have to create a bootable media that will enable you to access the drive to be scanned. Think of this as a way to circumvent around the corrupt MBR to get to your files.
You'll need a second computer and an empty thumb drive-or CD/DVD, but USB works best. Plug the thumb drive into the working computer, then install and Launch Recoverit on it. Click on "Recover from Crash Computer" and then on "Start".
You'll then be taken to a page where you can create the bootable media with 2 options to choose from. Select either USB or CD/DVD and hit "Create". You'll see a prompt asking you to format the USB. Click "Format", then on "Create" again.
The next window you'll see will be Recoverit downloading the firmware needed to create the bootable media. Once done, Recoverit will proceed to format the drive and create the bootable media. Unplug the USB or eject the CD/DVD once you see the prompt notifying you of the completion of the process.
Step 2 – Boot Computer with Bootable media
Plug the bootable thumb drive or insert the CD/DVD into the system with the damaged MBR-but before doing this, make sure you've changed settings in BIOS. Set it to boot from the CD/DVD or USB drive.
Restart your system and you'll be able to boot into the faulty system. Plug in an external drive into the system too, because you'll need it to save the files you recover.
Step 3 – Select Recovery Mode
You'll be given two options in the subsequent window: "Hard Disk Copy" and "Data Recovery". Select the latter and then select the drive where the files you want to recover were once stored. Click on "Start" and Recoverit will begin scanning the drive for your files.
Step 4 – Recover and Save
As Recoverit scans the drive, the list of your files will keep growing. You'll even be able to preview them before the final stage of recovery. Even better, you can select and preview the different file types or formats too-pictures, videos, etc.
Once the scanning is done, just choose a location to save the files (the external drive you plugged in earlier) and click on "Recover". Recoverit will handle the rest.
Master Boot Record (MBR) is a key part of your system's booting process; this has been made quite obvious above but just for emphasis, take note. This is why you must learn how to fix it in case it gets damaged or corrupted. Now that you do know how to fix it, aren't you glad you read this manual?
