BOOTMGR is Missing: Fix for Windows Vista, 7, 8, 8.1, 10

Here we can see, “BOOTMGR is Missing: Fix for Windows Vista, 7, 8, 8.1, 10”

In Windows Vista, Windows 7, Windows 8, Windows 8.1, or Windows 10, the “BOOTMGR is Missing” boot problem can be fixed.

BOOTMGR error messages that aren’t BOOTMGR:

“BOOTMGR is missing” is the most probable error message to appear. “To restart, press Ctrl+Alt+Del,” however, your PC may also say, “Couldn’t detect BOOTMGR.”

These terms allude to the same problem that is preventing your computer from booting up.

Why BOOTMGR is missing appears

When you switch on your computer, the BIOS begins the POST (Power On Self Test) steps before loading your Windows copy. After the POST process is completed and Windows starts to load, the problem occurs.

The POST is a group of operations that run soon after turning on your computer, such as checking if your RAM, peripheral devices, and other hardware components are functioning correctly.

After BIOS has completed these processes, the Windows boot loader begins, which is where this issue will display.

Many causes can cause the BOOTMGR problem, including boot sector infections, failed Windows installs or upgrades, or crashed hard discs.

When your PC tries to boot from a non-bootable hard disc or flash drive, it frequently fails to load and displays this error.

Other BOOTMGR fixes are corrupt or missing

We’ve included 5 solutions below that you can use right now to fix this problem. Go through each one step by step, from 1 to 5, to see which one will work best for you.

Fix 1: Remove non-bootable discs

Check for any existing media in your USB ports, floppy discs, or optical drives as the first and easiest remedy (CDs, DVDs).

If your computer tries to boot from one of these drives with non-bootable media inserted, the BOOTMGR error will occur. The problem should go away if you remove a USB drive or CD from which the machine was trying to boot but couldn’t.

After it has vanished, change the boot order in BIOS to ensure that your computer boots from the hard disc instead of any other non-bootable drives the next time.

This is recommended to avoid similar problems in the future.

Fix 2: Run Startup Repair

If you have the Windows installation CD, this method will work.

The ways to fix the BOOTMGR error with an installation CD are as follows:
