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.

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:

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 An out-of-date BIOS model can certainly cause the “BOOTMGR is Missing” error.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

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.
