- BOOTMGR is missing Hit Ctrl Alt Del to restart
- BOOTMGR is missing Hit any key to restart
- Couldn’t find BOOTMGR

Solutions To Fix ‘BOOTMGR Is Missing’ Errors:
Here are some easy ways to fix the error:
Step 1: Restarting PC
Initially restart your computer as the BOOTMGR error could be a chance.
Step 2: Checking Extras
Then check your USB ports, optical drives, and floppy drives for media. Certainly, the “BOOTMGR is Missing” error will occur if your computer is trying to boot to a non-bootable disc, floppy disk, or external drive.
Important: After you find that this is the reason for your problem and it’s happening daily, you probably want to consider modifying the boot order in BIOS so the hard drive is mentioned when the first boot device.
Step 3: Check the boot order in BIOS
Here you should check the boot order in BIOS or ensures the exact hard drive or other bootable device is listed first. Let suppose you have more than one drive. If the incorrect drive is listed first, you could then view BOOTMGR errors.
We sort of hit on this in the steps mentioned above. But it’s necessary to call out specifically that you might have the wrong or incorrect hard drive listed since lots of BIOS/UEFI systems enables you to specify a specific hard drive to be booted from first.
Step 4: Reset all cables
In this step, you should try to reset all power cables or internal data. BOOTMGR error messages could be occurred due to unplugged, loose, or faulty power or controller cables.
Simply try to replace the SATA or PATA cable if you check it might be faulty.
Step 5: Perform a Startup Windows Repair
This type of installation just replaces any missing or faulty files, like BOOTMGR.
Also, a Startup Repair is a rare fix for BOOTMGR issues, don’t fret if it doesn’t resolve your issue. Just continue to fix it—something will definitely work.
Step 6:
Here you write the latest partition boot sector to the Windows system partition to correct corruption, configuration issues, or other faults.
The partition boot sector is an important part of the boot process, so if there’s a problem with it, you’ll then view issues such as “BOOTMGR is Missing” errors.
Step 7: Rebuild BCD
You can try to rebuild the Boot Configuration Data. It is quite similar to the partition boot sector, a faulty or wrongly configured BCD could cause BOOTMGR error messages.
Note: The following steps can help to resolve the BOOTMGR issue. If you’ve ignored any of the above ideas then you may have to check a fix to this problem!
Step 8: Check Drive Setting
Then check the setting of other drives or hard drives in BIOS and ensure they are correct. The BIOS configuration tells the PC how to use a drive, so wrong settings can cause issues like BOOTMGR errors.
Important: Here’s usually an Auto setting in BIOS for optical drive configurations or hard disk, which is usually a secure bet if you don’t know what to do.
Step 9: Update motherboard BIOS
To fix this issue simply update your motherboard’s BIOS. An out-of-date BIOS model can certainly cause the “BOOTMGR is Missing” error.
Step 10: Perform a clean Windows Installation
Simply try to perform a clean Windows installation. This type of installation will fully erase Windows from your computer and reinstall it from scratch. While this will almost fix any BOOTMGR errors. Well, it’s just a waste of time process because of the fact that all of your data must be recovered and then later restored.
If you can’t gain access to your files to recover them. You must understand that you will lose all your important data all if you continue with a clean installation of Windows!
Step 11: Install New Windows Copy
Try to replace the hard drive and then install a new copy of Windows. If it fails to install, including the clean installation from the last step, you can then face a hardware problem using your hard drive.
Step 12:
Let’s suppose it’s not a hardware problem, your BOOTMGR should be resolved.
