BOOTMGR is missing HELP!

Solution

Important: The following troubleshooting steps are much less likely to help fix your BOOTMGR problem. If you've skipped any of the above ideas then you may have overlooked a very likely solution to this problem!

3. Check the hard drive and other drive settings in BIOS and ensure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including BOOTMGR errors.

Note: There's usually an Auto setting in BIOS for hard disk and optical drive configurations which is usually a safe bet if you're not sure what to do.

Update your motherboard's BIOS. An outdated BIOS version can sometimes cause the "BOOTMGR is Missing" error.

4. Perform a clean installation of Windows. This type of installation will completely remove Windows from your PC and install it again from scratch. While this will almost certainly resolve any BOOTMGR errors, it's a time consuming process due to the fact that all of your data must be backed up and then later restored.

If you can't gain access to your files to back them up, please understand that you will lose them all if you continue with a clean installation of Windows!

5. Replace the hard drive and then install a new copy of Windows. If all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive.
