Fix: Bootmgr is Missing in Windows 10/8/7

This is one of the most common boot issue you might come around, in the Windows operating system. Are you receiving the Missing Boot Manager error? In this article I will tell you how you can fix the Bootmgr is Missing error message in Windows 10/8/7.

Bootmgr is Missing

Step 1:

Insert the Windows Installation or Repair disk into your drive and reboot the System. You will be prompted to “Press any key to boot from disk” so go ahead and press Enter.

Step 2:

Then it will give you language selection option click Next.

Step 3:

You will now get the option to “Repair your Computer“.

Step 4:

Select Repair your computer option and the Operating System i.e. Windows 7 next. Click Next.


On some occasions you may not find any operating system listed. Don’t panic just click Next!

Step 5:

Now click on “Command Prompt“.

Step 6:

Type in the following commands:

  • bootrec /fixboot
  • bootrec /fixmbr
  • bootrec /RebuildBCD

Sometime you may need to change the directory from X:\Windows\System to C:\ type in the command cd\ then c: then run the commands.

Once you finish running those commands, reboot the system and see if it boots. It should! If not then run Startup Repair 3 different times.

    thanks so much, putting the command prompt instruction extra was a lifesaver….

  2. Dude

    In the video you type the commands bootrec /fixboot
    bootrec /fixmbr
    bootrec /RebuildBCD in reverse order.

  3. do these commands have to be in order?

    i asked the same question many times somewhere in other forums whatsoever…
    what if i don’t have a windows 7 installation or repair disk at my fingertips?
    any tools available for backing up boot elements of the running sytem and preparing a boot restoration at machine boot?

  5. You can create a system repair disc from any functional Windows 7 machine. Just search “Repair” and it should be the first hit.

    Sorry I didn’t mention ..
    First I would recommend /RebuildBCD, /FixMbr then /FixBoot

  11. Hi Josh,

    Have you tried the commands mentioned in the video? Those are Fixboot commands in Command Prompt at Start Repair screen i.e.

    Bootrec /RebuildMBR
    Bootrec /FixMBR
    Bootrec /FixBoot

    Watch the video and let me know if it works for you.

    i upgraded from windows 7 to 10 so it won’t repair. there were two other options one i can’t remember and one would make me lose all my files the other won’t but i can’t do that option b/c i’m using the windows 7 installation after i already upgraded to 10. HELP.
