What Is MBR?

MBR stands for Master Boot Record, which is basically the information in the first sector of any diskette or hard drive that identifies where and how an operating system is located so that it can be loaded or boot into the computer's main storage or Random Access Memory (RAM).

The MBR is often called a "master partition table" or "partition sector" because it involves a table that locates each partition into which the hard disk has been formatted. MBR also consists of a program that reads the boot sector record of the partition containing the operating system to be loaded into RAM.

Talking about the basic features of MBR, these are as follows:

• The maximum number of primary partitions possible on an MBR disk is 4. Each partition needs 16 bytes of space.
• MBR partitions are of 3 types, i.e., Primary Partitions, Logical Partitions, and Extended Partitions.
• The partition table in MBR consists of details regarding the extended and primary partitions only.

Symptoms of a Damaged or Corrupted MBR

As stated above, Master Boot Record or MBR is essential to booting the computer. Therefore, when it is corrupted or damaged, Windows 11 will fail to load the disk and encounter multiple boot errors.

But if you're confused about identifying a damaged MBR, then we have your back. Here's a list of boot errors that you will face on Windows 11:
