    BOOTMGR is missing


    I just did a re-installation of Windows 7 x64 on my computer, and I am getting the dreaded "BOOTMGR is missing" error. The previous operating system was also Windows 7 x64. I have 4 internal HDD, but I am reinstalling to the same drive that I originally used. I reformatted the drive when I did the installation.

    I have done a lot of searching on this topic to try to find a solution. I'm amazed at how common this error appears to be, and yet there doesn't seem to be a clear and consistent answer for solving it. Why is this so difficult to resolve? Can anyone help me get this fixed?

    I tried that. I clicked the repair option, but it didn't fix the problem. Thanks.

    This is from a user here raj1402 Try this method:

    you can rebuild the BCD store by using the Bootrec.exe tool in the Windows Recovery Environment. To do this, follow these steps: - Get your Windows 7 installation DVD and pop it into your drive.
    - Then restart your computer.
    - Press a key when you are prompted.
    - Select a language, a time, a currency, and a keyboard or another input method, and then click Next
    - Click Repair your computer
    - Click the operating system that you want to repair, and then click Next
    - In the System Recovery Options dialog box, click Command Prompt
    - Type bootrec /rebuildbcd and then press ENTER

    • If Bootrec runs successfully, it will present you with the installation path of a Windows directory. To add the entry to the BCD store, type Yes . A confirmation message appears that indicates the entry was added successfully.

    • If Bootrec cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order shown below: (Remember to press ENTER after each command)

    bcdedit /export C:\BCD_Backup

    ren c:\boot\bcd bcd.old

    bootrec /rebuildbcd


    - Restart the computer.

    Always unplug all other HD's when installing Win7 unless you want to create a dual boot with an older existing OS.

    It is possible you have boot files on one of the other HD's interfering with Win7 install.

    Please post back a screenshot of your full Disk Management drive map and listings, using Snipping Tool in Start Menu, attaching file using Paper Clip in Reply Box.

    metalmania31, thanks for the instructions. I followed your directions. Bootrec did not run successfully (no Windows installations were found), so I followed your other instructions. The instruction "rename c:\boot\bcd bcd.old" return an error message that indicates the file could not be found. I can confirm that the boot directory exists, but the file could not be found within the directory. I executed the third instruction anyway and rebooted. The problem still persists.

    Gregrocker, I cannot capture the screen shot that you requested because I cannot boot into Windows. The BOOTmgr error message happens before the operating system can load. I can't get in to Windows at all.

    I have unplugged all other drives, and I'm in the process of doing a clean install on the single remaining drive. I believe this will work, but what will happen when I plug in the other drives? Will it once again find the old files and hose up my new installation?
