How to Recover Data from Corrupted MBR Effectively

How Can We Recover MBR if It Gets Corrupted?

A master boot record (MBR) is a special type of boot sector at the beginning of partitioned computer storage devices. It provides important information about the disk's partitions and the bootloader and is used to identify the location of an operating system.

If the MBR is corrupted or damaged, it will prevent you from booting the Windows operating system and may result in the loss of all partitions on the syste as well as data.

How can we recover the MBR if it gets corrupted? With the knowledge provided in this detailed guide, you can recover data from a corrupted MBR in 3 top ways. Let’s find out more!

Causes and Symptoms of MBR Corruption

Before recovering data from damaged MBR, let us first explore why the MBR gets damaged and the common symptoms of MBR corruption.

Causes of MBR corruption

1️⃣ Accidentally deleted files related to the Windows operating system

2️⃣ MBR suffers from a virus/malware infection

3️⃣ BIOS does not detect the hard drive where the Windows operating system is installed

4️⃣ Hard drive or external HDD is physically damaged or contains bad sectors

5️⃣ Sudden power outage causes system crash

Symptoms of MBR Corruption

1️⃣ PC fails to boot from the Windows operating system and displays some error messages:

• Operating System not found
• Error loading operating system
• Invalid partition table
• No boot disk has been detected
• Reboot and select proper boot device, Or Insert Boot Media in Selected Boot Device

2️⃣ All volumes on the hard drive are not displayed properly

3️⃣ Hard drive/external drive not recognized in Windows

How to Recover Data from Corrupted MBR (2 Ways)
