Nobody likes to turn on their Windows PC only to see the message “Bootmgr is not found,” so what can you do about it?
Bootmgr is an application that runs when you start your PC, loading the operating system from the hard drive. However, when the PC cannot find this program, Windows will not start. When this happens, many questions come to mind. Is the computer about to disappear? Is that hard drive about to break? What happens with all that data on the disk?
Before doing anything else, it is always a good idea to restart the computer and let Windows try again to boot. If it starts, it would be advisable to perform some diagnostic tests from Windows to make sure there are no problems.
When Windows usually reloads, you should not worry too much, however, if this incident still happens, this could indicate that a more significant problem is looming.
If “Bootmgr is missing” still appears and Windows still does not start, you can have Windows perform a repair to reinstall Bootmgr. Before doing this, you need to configure your PC to boot from your Windows disk or USB drive.
This involves accessing the BIOS settings of your PC, which can usually be done by pressing the F2 or Del key when the machine is turned on for the first time. In the boot options, choose a drive or USB drive to start from, exit the BIOS setup and save the changes.
Startup repair in Windows 10 and Windows 8
The use of the startup repair can repair all lost or damaged files, including Bootmgr. However, this requires a Windows system installation medium, if you do not have one, create one by visiting the Microsoft download page and click the Download Now tool to download MediaCreationTool.
With the USB disk created, restart the computer, and when you see a black screen that says “press any key to start from CD or DVD,” press Enter on your keyboard.
Select your language, time and keyboard, then click Next. Press “repair your PC” in the lower left. Next, click on Troubleshoot, then on Advanced Options and then on Startup Repair.
Once you have finished, restart the computer to see if this worked.
Startup repair in Windows 7
The repair of Windows 7 is very similar to the repair of Windows 10 and Windows 8. In Windows 7, you should start from the Windows 7 disk. You should wait for the installation process to load the files. Select the language to install, the time and currency format, and the keyboard or input method you want to use, then click Next. In the lower left corner of the “Install Windows” window, click on the “repair your computer” link.
This will start the Windows 7 system recovery options that include several appropriate diagnostic and repair tools, one of which is Startup Repair.
