Bootmgr is missing

Issue : Unable to boot to windows error “bootmgr is missing”

Note   Note
Before trying the step below please run startup repair first


Solution :




1. Boot the computer from Vista OS DVD.
  • Click on Repair Your Computer.

  • Click on Command prompt.

  • At the X:\Sources prompt, type bcdedit /export C:\BCD_Backup and press <Enter>

  • Type c: and press <Enter>.

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

  • At the C:\Boot prompt, type attrib bcd -s -h -r and press <Enter>.

  • At the C:\Boot prompt, type ren c:\boot\bcd bcd.old and press <Enter>.

  • At the C:\Boot prompt, type bootrec /rebuildbcd and press <Enter>.

  • The Boot Configuration File will be rebuilt at this point. Once it finishes, type exit and press <Enter>. Click the Restart button . ;)

Hi Dinesh,

Good one. I would like to add few points here. Instead of trying RebuildBCD/Recreate as a first step, we could try startup repair at least 3 to 5 times which would search for problems and fix it.

Here are some commends

bootrec /RebuildBcd - Use this option when you must completely rebuild the BCD
bootrec /FixMbr - writes a Windows Vista-compatible MBR to the system partition
bootrec /FixBoot - writes a new boot sector to the system partition by using a boot sector that is compatible with Windows Vista

Hi Dinesh,

If the automated startup repair doesn't do it - even after a few goes , as Prasath says,

I would try this first

bootrec /fixmbr

your dvdrom drive letter:\boot\bootsect.exe /nt60 all /force

del C:\boot\bcd

bootrec /rebuildbcd

Close cmd prompt, remove dvd, Reboot.

Fingers crossed.

your dvdrom drive letter: needs to be the letter as seen in WinRe, e.g. E: or F: etc.

I have the same problem with bootmgr is missing.
I just went through the steps listed.
Just at At the C:\Boot prompt, type ren c:\boot\bcd bcd.old and press <Enter>.
It states there is a duplicate file or file is not found.

OK, just tried that and it states.

Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.
Just has nothing changed.

I was able to reformat this once before when the hard drive was full of games with no problems. I even send a email to emachines.com and they want a receipt to help in any way.

I would recommend you to do a clean install using Vista DVD. Sorry mate but some problems are unfixable withour reinstalation. :(

I was trying to do a clean installation.
Seems I have no drivers not able to do a clean installation of Vista.
The computer does not see any thing on the CD.
So now it's back to XP.
Edit note.
I just check my older computer and the Windows Vista says it will work on it.
So maybe after I get the newer computer running again on XP I will be able to install the Vista afterward.

Thanks anyhow.

Ive removed the 2 hardrives and tried booting it from just the cd/dvd drive it says operating system not found. I removed the cd drive and replaced it just to make sure its not the cd drive which is faulty but im getting the same problem wit the new drive so the cd drive is ok too :confused:

Any ideas what it can be it wont go into bios nor will it go pass bootmgr is missing

Try going into Bios and disabling AHCI mode , set it to ATA or IDE, see if that helps.

Can you ( not it ) go into Bios?

Startup and press F2 or Del, or whatever it says for "setup" on the screen.

If you have any external drives/devices connected - disconnect them.

Set the Hd you want to install on as the first boot device.

See if the installation continues.

If not,

Use the boot pop up menu selection on the startup screen ( e.g. press f11 or whatever for "boot menu" )

Arrow down to cdrom drive - put the dvd in , press enter.

It will probably ask to confirm - press enter again.

Hope it helps

That is ok.

See if you can find the disk controller and set it to ATA - not AHCI.

You might just have donesomething like this :

Changed RAID ON to RAID AutoDetect / ATA

That should be fine.

Then try as per my previous post.

Bios are not all the same - you just need to look for something similar.

Where you saw those Raid settings is probably it.
