Restart the PC. The BOOTMGR error could be a fluke.
Check your optical drives, USB Ports, and floppy drives for media. Often times, the "BOOTMGR is Missing" error will appear if your PC is trying to boot to a non-bootable disc, external drive, or floppy disk.
Reseat all internal data and power cables. BOOTMGR error messages could be caused by unplugged, loose, or malfunctioning power or controller cables.
Try replacing the PATA or SATA cable if you suspect it might be faulty.
Perform a Startup Repair of Windows. This type of installation should replace any missing or corrupt files, including BOOTMGR.
Even though a Startup Repair is a common solution for BOOTMGR problems, don't worry if it doesn't fix your problem. Just continue troubleshooting - something will work.
Write a new partition boot sector to the Windows system partition to correct any possible corruption, configuration problem, or other damage.
The partition boot sector is an important piece in the boot process so if there's any issue with it, you'll see problems like "BOOTMGR is Missing" errors.
Rebuild the Boot Configuration Data (BCD). Similar to the partition boot sector, a corrupted or incorrectly configured BCD could cause BOOTMGR error messages.
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!
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. Update your motherboard's BIOS. An outdated BIOS version can sometimes cause the "BOOTMGR is Missing" error.
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!
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.
