How to Fix the MBR on a Windows Server (2 Quick Ways)

Can I fix the MBR?

MBR is one of the two most common acronyms that enthusiastic PC users throw around quite often. In case you didn't know, MBR stands for Master Boot Record. It's also referred to as the primary partition table or the partition sector. The MBR is a part of your hard drive that stores information about the disk partitions. The MBR is pretty useful since it acts as a bootstrap loader for the operating system. An MBR partition has two essential components: the master boot code and the disk partition table. These two components work together to transfer the program in the boot sector into an efficient startup process. The MBR can get damaged quite easily. The reasons for the damage are subjective. From improper ejection to virus infections, the MBR can get corrupted due to simple reasons. It's crucial to fix the MBR as soon as possible to avoid further complications.

How to check if the MBR is damaged?

If your system experiences any of the following, you might not be able to boot into your operating system. The main causes of MBR failure and error messages include:

• Hard drive failure: If your hard drive is malfunctioning, your operating system will detect a damaged MBR.
• Virus infection: Sometimes we insert external devices without checking for viruses that could harm our system. The presence of a virus can also cause MBR damage. If the virus is severe, you might lose important data.
• Missing operating system: If you can't see your operating system, chances are your MBR is corrupted.
• Invalid partition table: If you're unaware, an invalid partition table is an error that occurs in the operating system's partition. Users will see a black screen and won't be able to restart their computer system.
• Non-system disk error: A non-system disk error is one of the main causes of MBR corruption in the operating system.
• System shutdowns: If your system is shutting down unexpectedly frequently, you should check your MBR.

If you see that your operating system is not running correctly or fails to start up properly, you should repair the MBR.
