How to Fix the Error 'BOOTMGR is missing'

If you computer does not boot up normally and you receive an error message similar to the following:
BOOTMGR is missing Press Ctrl Alt Del to restart

BOOTMGR is missing Press any key to restart

Couldn't find BOOTMGR

These messages indicate the file 'bootmgr' or the boot sector is damaged or missing.
'BOOTMGR' is a hidden system file in Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows 8.1, Windows Server 2012 and Windows 10. It is an important component of Windows'new boot manager, and is loaded by the boot sector.

When a computer boots from BIOS mode, it loads and excutes the boot code of MBR (Master boot record) first. Then, the active partition boot sector is loaded. When the boot code of boot sector is running, it finds the bootmgr file in the system partition.

When a computer boots from UEFI modek, the file "amd64\efi\boot\bootx64.efi" in the EFI system partiiton is launched first on a 64 bit computer and the file "x86\efi\boot\bootia32.efi" in the EFI system partiiton is launched first on a 32 bit computer. Next, the loaded EFI boot file loads the bootmgr.efi file.

The 'BOOTMGR' managers the boot menu of Windows. It reads the BCD file to provide the boot menu and boot options. If the 'BOOTMGR' file is missing, compressed or corrupted, Windows will not boot.

If you are prompted 'bootmgr is missing', you can use either of the following two solutions to fix your problem and to make your computer boot again normally.

Solution one: Use Windows 7 Installation DVD to fix the Error 'BOOTMGR is missing'

Insert your Windows 7/8/8.1/10 Installation DVD to your computer CD/DVD drive.
Restart, setting BIOS to boot your computer from the DVD OR boot from your computer by selecting boot menu.
When you are prompted "Press any key to boot from CD or DVD", press a key. (If you do not get the message, you need to set BIOS and use boot menu to ensure boot from the DVD.)
Once the "What to know before installing Windows" screen appears, click the <Repair your computer> button NOT the <install now> button.
The Windows 'System Recovery Options' tool will be launched and begin a search for the current Windows installation, When the search is completed, click <Next> to continue.
When you see the System Recovery Options dialog box, click the <Startup Repair> button.
Please wait until the 'Startup Repair' operation is completed. Reboot your computer, and check to see if the boot problem has been repaired. If it persists, you need to use a Lazesoft recovery medium to fix your computer using the alternate solution given below.
