BOOTMGR missing win 7 install

Dear EE,

I have been trying to clean install my preferred option:  windows  XP.  However I was plagued with missing NTDLR messages and tried several of the solutions ofered on Experts Exchange.  All unsuccessful.

I had an upgrade copy of windows 7 so tried to clean install this (using option to format the  c: drive).  As it was an upgrade it did not accept my product key, but with microsoft help centre (telephone) I double installed it and all seemed fine.  Till they got off the phone and i shut down / restarted.

I reset the boot order to use hard drive first.

Now I have a BOOTMGR is missing message (press c+a+d TO RESTART).

i am at my wits end. Please, any suggestions?

    •Insert your Windows 7 DVD into your optical drive(DVD drive) and restart the system.
    •Boot using this DVD by pressing any key when windows asks "Press any key to continue..".
    •Select your language in the first screen and click "Next".
    •In this Window, select the option named "Repair your computer".
    •This tool will search for the installation directory for a minute.Once it finished, click "Next" once again.
    •Under Recovery Tool, choose the option named "Startup repair". Now,Windows will try to repair your startup problem and gives a message to restart your system.
    •Restart your system to finish the process.

    You can try to resolve this issue by downloading a recovery disc for win7. I have had the same issue and it was successfully with booting the recovery disc and run a repair.

    Thanks for that .

    I followed your instructions and it all went through. I got into windows.  However on shut down and reboot -- same story, bootmgr is missing ??!!

    Hello -

    well as it turns out: the microsoft call centre agent figured out that windows installed itself on the second drive in the machine, renaming itself accordingly.So far as i remember, i did point it to the drive i wanted, but since i was doing the install with the phone to my ear (microsoft help call centre) I may have pointed to the wrong drive at the time.

    All seems to be working now, but i will not close the question until a couple more boots.

    many thanks for your help.

    perhaps i spoke too soon.

    MS agent suggested that i go into the boot menu and point to the other drive (maxtor) as suggested above. I did that and windows loaded.

    However on shut down and reboot - same old story: bootmgr is missing
     If I interrupt the boot and point to the maxtor drive , even if it is already pointing to the maxtor, i.e. I make no actual change - windows opens. but without interrupting the boot by going into the the boot menu , it fails (bootmgr missing)
    I haven't tried going back to the other drive (which used to carry the OS) in bootmenu.

    Boot the computer into Windows 7 using your workaround, then open a command prompt with Administrator privileges by right-clicking on Command Prompt and choosing "Run As Administrator."

    Run the following three commands within the command prompt:

    BCDEDIT /set {bootmgr} device boot
    BCDEDIT /set {default} device boot
    BCDEDIT /set {default} osdevice boot

    Open in new window

    Restart the computer.

    Thank you for all your support offers.

    On this occasion I have resolved the question independently - on the telephone (a series of calls to me following my first contact and some email exchanges).

    Effectively I had a hardware fault (could have been incorrect jumper settings) which caused some files to be loaded on a second drive by the windows install.  By disconnecting the slave drive I forced windows to install correctly on the master (SATA) drive before reconnecting the EI|DE drive as slave.

    Many thanks for your help.

    This was an independent solution, arrived at with Microsoft help centre support, as indicated in the closing post.

    many thanks
