7 Ways to Fix BOOTMGR image is corrupt the system cannot boot in Windows

When a PC is powered on, the BIOS selects the bootable hard drive, then in that particular hard drive it looks for the MBR code. This MBR code takes necessary steps to load BOOTMGR. 

BOOTMGR (Windows Boot Manager) is a kind of essential boot loader files which allows different operating systems to run on the same computer. Most likely when these files get corrupted, it will effect the process of booting. Which means that this error BOOTMGR image is corrupt is as a result of corrupt BOOTMGR files. However there are various methods available to sort out this error on your own.

In this article, I will be illustrating the 7 Ways to Fix BOOTMGR image is corrupt the system cannot boot in Windows. Finally you will be able to fix this in all the popular PC models. 

Let's get started,

1. Check the Boot Sequence

Most often this error occurs as a result of wrong disk listed first in boot order. This includes non-bootable optical drives such as external hard drives, floppy disk drives and USB drives. Therefore, always ensure to check the boot sequence in BIOS. If not move the hard drive to the top order. 

2. Perform Startup Repair

Startup repair is a free tool available for windows users for fixing common problems related to the operating system. This includes replacing corrupt BOOTMGR files. It necessarily scans the system for finding missing and damaged files. For this however you need a windows installation disk. 

3. Check the RAM

Sometimes the culprit of this issue may actually be the RAM. The RAM present on your computer may be defective causing this error. If you have more than one RAM installed, one of them may have gone bad. Hence, remove the RAM and clean the connection point with a soft cloth.
