    About a month back, my 5 year old PC died on me, due to simultaneous failures of the motherboard, PSU and the main HDD which had a Windows 7 installation. I went and got replacement parts and got my computer running.

    I installed windows onto the new drive and my computer would boot up. But weirdly enough, it detected TWO copies of Windows 7. Trying to boot the second copy of "windows" would end up in an error. I didn't pay much attention to it, because all it took was me hitting enter for the boot sequence to continue.

    But recently, my secondary HDD which I had with me has also failed, and I've taken it out. But now, my computer doesn't recognise that I have an OS installed on my still-functioning main HDD. I get a "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key." error whenever I try to boot.

    I figured that my secondary HDD contained the BCD.

    I read up on this error on google, and tried rebuilding the BCD on my new primary HDD, but to no avail. I get the "BOOTMGR is missing" error.

    I tried using the Win7 CD that I installed my OS with, but I get this error when I try to select my OS from the list to repair: "This version of System Recovery is not compatible with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of Windows."

    If I hit Next without selecting my OS from the list and go straight to repair, I get this error among others:
    ---------------------------
    Boot manager is missing or corrupt.

    Repair action: File repair
    Result: Failed. Error code = 0x15
    Time taken = 0 ms
    ---------------------------

    The immediate error screen that comes up after I finish the Startup Repair shows this:

    Go here: http://support.microsoft.com/kb/927392/en-us

    Click on Bootrec.exe options and follow the instructions to perform a complete rebuild of the BCD

    You need to boot the system with the Win 7 disc and get to the Command Prompt from the recovery options. If you can't get there let me know.

    Ok. I did a LOT more searching, going to the deep depths of google search.

    And it turns out, the ONLY thing I needed to do was use the 64-bit Windows 7 *RECOVERY* CD.

    I found an ISO online, downloaded it, burnt it onto a CD and used it to repair my Boot Manager error.

    What a simple fix, but such a pain in the *** to figure out.

    I hope this thread will help others who have the same problem.

    All you need is the RECOVERY disc.

    Thanks for the update. I'm confused by the fact you said you were using the same install CD to get to the recovery console that you had used to install Windows "I tried using the Win7 CD that I installed my OS with" which would normally do the same job as a Recovery CD :confused:

    Yes! That's the REALLY weird part!
    Apparently the recovery disc has something the original install disc doesn't.

    It's actually round the other way, the Recovery disc only has the Recovery Console and no OS and the Install disc has both. Anyway, all is well now so the job is done.
