Perhaps you’ve never heard of the term BOOTMGR. BOOTMGR is an abbreviation for boot manager, which is part of the file system that is responsible for booting Windows. Furthermore, the boot manager is in charge of all operating systems. Microsoft owns it.

This message must be related to the boot process or the process by which your laptop or computer is loading to enter the operating system’s main display. If you have turned on your computer and discovered it, we will explain what is going on and what you can do, with various solutions based on your circumstances and capabilities. Before you panic, the first thing you should do is pay attention to what the error message says, then restart and see what happens. If this does not resolve the issue, see below for instructions on how to save the situation on your computer.

What exactly is Bootmgr?

Bootmgr is Windows Boot Manager, a program that is loaded from the volume’s boot code and is located in the boot directory of the active share. It is a hidden file that can only be read.

The boot sector is a much more important component than you may realize, as it is responsible for the operating system’s proper startup. Furthermore, it is in charge of running the Winload.exe process, which loads essential device drivers as well as a portion of the operating system kernel.

It is possible that Bootmgr is not present or is missing, as this problem can occur in a variety of other situations, which we will discuss below, as well as provide you with various solutions to the error.

Why BOOTMGR is missing appears

When you turn on your computer, the BIOS begins the POST (Power On Self Test) process before booting your Windows copy. The error appears immediately after the POST process has completed and Windows has begun to load.

The POST is a set of routines that are executed immediately when the PC boots up, such as checking to see if your RAM, peripheral devices, and other hardware components are operational.

After BIOS has completed these routines, the Windows boot loader begins, which is where this error will appear.

Many factors can cause the BOOTMGR error, including boot sector viruses, failed Windows installs or updates and crashed hard disks.

A common cause of your PC failing to load and displaying this error is when it tries to boot from a non-bootable hard or flash drive.
