This error typically appears when your computer is unable to boot from the Boot Manager. While it can be intimidating, there are several steps you can take to resolve this issue. In this article, we’ll take you through the process of understanding the Bootmgr error, identifying its causes, and providing you with step-by-step solutions to help you fix the “Bootmgr is missing” error and get your PC up and running again.

Understanding the Bootmgr Error

If you’ve turned on your computer only to find a message that says “Bootmgr is missing” staring at you, don’t worry — you’re not alone. The Bootmgr error is a common issue that can occur for a variety of reasons. Here’s what you need to know.

What is Bootmgr?

The Bootmgr (short for “Boot Manager”) is a small program that is responsible for loading your operating system when you turn on your computer. In simple terms, it tells your computer what to do next after the BIOS has finished running.

What Causes Bootmgr Error?

Several things can cause the Bootmgr error. Some common causes include a damaged or corrupted hard disk, a virus infection, or problems with the Master Boot Record (MBR).

How Does Bootmgr Error Affect your PC?

The Bootmgr error can prevent your computer from booting up properly. It may result in your operating system not loading at all, which can make it impossible to access your files or use your computer.

Causes of Bootmgr Error

Let’s take a closer look at some of the most common reasons you might experience the Bootmgr error.

Corrupted or Missing Files

Sometimes, important files that your computer needs to boot up properly can become corrupted or go missing. This can prevent the Bootmgr program from doing its job.

Corrupted Hard Disk

If the hard disk that contains your operating system becomes corrupted, it can prevent your computer from starting up correctly.

MBR Failure

The MBR is a crucial part of your computer’s boot process. If it becomes damaged or corrupted, it can cause the Bootmgr error.

Boot Sector Virus

A virus can infect your computer’s boot sector, causing the Bootmgr error. This can happen if you’re not careful about what you download or if you don’t have up-to-date virus protection.

Troubleshooting Bootmgr Error

Luckily, there are several things you can try to fix the Bootmgr error.

Checking for Connected Devices

Sometimes, external devices like USB drives or external hard drives can interfere with your computer’s boot process. Check to see if anything is plugged in and remove it if necessary.

Disconnect External Devices

If you’re still having trouble, try disconnecting all external devices (except for your keyboard and mouse) and booting up your computer again.

Changing Boot Order in BIOS

If your computer is trying to boot from the wrong device, you may need to change the boot order in your BIOS settings.

Checking Hard Disk Connections

Make sure that all of your hard disk connections are secure. Loose cables can cause the Bootmgr error.
