Bootmgr is missing - Fix

How to Fix the "Bootmgr is missing" Error in Windows​

You may get this error while booting your computer.

   Information

This problem is not hardware related and can be fixed with a Windows 7 DVD OR a system repair disc.

Here's How:

NOTE: Sometimes it may take running a startup repair a few times before it fully fixes the startup issue.

1. Boot to the System Recovery Options screen.

2. Select the Startup Repair option. (See screenshot below)

3. Now click on Startup Repair. Run the startup repair and it will attempt to fix this issue.

NOTE: It will ask you to reboot your system. Reboot to see if it works. If it doesn't work, follow step 4.


4. Click on Command Prompt.
A) Type c: and press <Enter>.

   Note

C:\ is the drive letter where Windows 7 is installed. You may replace it with whatever drive letter you want where you have installed Windows 7.

B) At the C:\ prompt, type cd boot and press <Enter>.

C) At the C:\Boot prompt, type the following commands and press Enter after each command.

[B]bootrec /FixMbr[/B]
[B]bootrec /FixBoot[/B]
[B]bootrec /RebuildBcd[/B]

D) Now close the command prompt, remove the DVD and reboot your computer.
That's it,
Dinesh.

Thanks, you just saved me from smashing my computer to tiny bits and buying a new one. I almost lost my job because of this error. I had an important event and ended up borrowing a computer installing virtual DJ in a hurry. You guys are life savers. Thank you so much.

bootmanager missing

I tried the changes detailed by Dinesh .They all completed successfully but I was left with zero installations. Then I used another correction (somewhere in this thread but I cannot locate again) which was to change the installations from zero to one. Which l applied and it left me with a system which will load the repair disk , leaving me with a WINDOWS BOOT MANAGER titled screen which displays .
File: \Boot\BCD
Status: 0xc000000f
Info: an error occured while attempting to read the boot configuration data
ENTER=Continue ESC= Exit

so I ENTER and the system starts but returns me to the exact same screen every time.
I am now in deep trouble and will have to pay many dollars if you good people cannot successfully guide my hand.

This has been fixed for months (Jan)

Thanks Funkyecat for your interest. However having read all the thread and tried as many of the fixes I could I am still stuck with the only screen available is the WINDOWS BOOT MANAGER and it leaves me two options, ENTER=Continue and ESC=Exit..
ENTER enables the F2 key which takes me to the SETUP screen which is fully functional but I presume is of no use at this time.
ESC returns me to the Windows Boot Manager screen which is where I started.
At power on I have tried all the F keys without success, ALT gets me to a screen showing BOOTMNGR is missing PressCTL,ALT,Del to restart which gives me the WINDOWS BOOT MANAGER which is where I started.
If there is a way to get to a screen where I can input commands I will appreciate any guidance.
Oh to remember my old DOS basics
If there is no way of getting to a screen where I can input commands then I will have to use the Boot or Nuke option which is at least less expensive than ACER offer.

Is there no-one who can help me with this problem. .I am very disappointed. So it was fixed months ago but the fix didn't fix my problem
When and if I have to nuke my disk how do I start with a blank disk. I have never had the opportunity before.
Any help will be appreciated.

 

[Dinesh]

Not sure why this method isn't working for you. I had tried this numerous times and has worked every time.
I'd suggest you to try again and follow each step.

 

[talisman]

Thankyou for responding Dinesh,I appreciate your help. I did use your method and while it worked it left me with "0 installations' I tried a method from another thread (I cannot remember) which offered to change from '0 installations to '1' installation. Unfortunately this left me with BOOT MANAGER MISSING from which I could not recover. After multiple failed attempts to recover some magic combination of Repair disk and an old saved Windows Image I am now able to use my laptop. I now face a long and interesting task of bringing everything up to date. Again thanks to you and the forum for being there when needed.

Will it work in my situation which is as follows:
I have three drives. Drive 0 is C drive, which has two partitions on it, one of which is unalocated and small. The other is healthy(Boot, Page file, crashdump, primary partition) shown in Disk Management. This boots windows, but only if my drive 2 is connected. Drive 2 shows healthy(System, Active, Primary Partition) Drive one is a clone of drive 0 created by Seagate Drive Wizard. How the system files get to be on one disk and the boot files on another I don't quite know.
If I remove drive 0 I get the missing MBR mesage.
Question: If I remove drive 0 should the solution shown above still work?
It is my main computer, and I have years of data on the drive that I do not wish to lose.
Looks to me that I need to get System and Boot onto drive 1, but I could be wrong.

To me it looks like you cloned 0 to 2, unless you have windows on all 3 partitions. You can use EasyBCD to move bootmgr to D.
http://www.sevenforums.com/tutorials/209885-bootmgr-move-c-easybcd.html
You will move to D though not C. You want the new larger drive to boot and load Windows, right?

Then, set Boot Order in BIOS to Drive2. After booting into Windows large Drive will be C, and should be boot and system.
And after that mark drive 1 as inactive - http://www.sevenforums.com/tutorials/197157-partition-mark-inactive.html

Hi All,

I dont have a compact disc to install again the OS that i had. That is w7 Ultimate x32.
I have a two desktop computer and in my other desktop the OS is not being recognized anymore and what I have done is I removed my hdd from the pc which is not working and I attached it to my other pc.

It is successfully discovered and installed.
So I formatted the d drive and just copy all the folders from my c drive and paste it on my d drive and after successfully transferred the files, I am now encountering the BOOTMGR is missing press/click ctrl+Alt+del to restart error.

how can I install again the OS ?
I dont have dvd or cd in my custom build pc/desktop.
would it be possible just to copy the BOOTMGR in my other desktop computer and have it paste in my other hdd which I formatted..

Please help! =(

I'm working on a friends sony vaio with this issue and I'm getting this error... (updating)

I found that the problem was that if the hard drive where you're reconstructing the MBR isn't listed in the BIOS Boot list (in the BIOS screens) then the RebuildBcd fails as happened with otakucho...you get that "Requested system device cannot be found message" Once I entered the drive that I wanted the MBR rebuilt on in the BIOS boot list, I could successfully do the RebuilBcd step.

I am also experience same prob. that otakucho has been facing. So i would like to know how to overcome this problem and how i can entered the drive and rebuild MBR in BIOS boot list?

Tried this and got blank screen

I went through all the above steps for my Win 7 installed on C drive. All the feedback was as show above and all seemed correct but when trying to reboot I get a blank screen with blinking cursor that just stays there. I can still boot to Windows by manual selection from the correct option list in the F11 menu.

Another of which I want to add is to remove any type of connected device either a removable storage drive.
