    Hi, you will need to use the full version of a Windows 7 install DVD.
    Start the pc from the DVD - if you can.
    Scroll through till you reach the System Recovery Options.
    Scroll down to Command Prompt.
    At the Command Prompt.
    Type the following, one at a time - then press Enter on the keyboard.
    BOOTREC /FIXMBR
    Press Enter.
    BOOTREC /FIXBOOT
    Press Enter.
    BOOTREC /REBUILDBCD
    Press Enter.
    Note space before /
    Remove the DVD and restart the pc.

    Did you make a recovery USB stick and DVD, while the pc was working Ok?
    If no, what version of Windows 7 is on the USB - DVD?
    To rebuild the 'Bootmgr' [Boot manager] you will need a full version of Windows 7 DVD - the same as installed, Home, Professional.

    Do you have another install DVD to check that the DVD drive is working and that the bios is set to boot from it?

    Its clearly mention that I had made a windows bootable cd or pendrive..
    Yes I have full windows on my cd and pendrive
    But the problem I that to boot from cd I have to press any key but when I press any key (if my pc was normal then it would have boot from cd or pendrive) then it shows bootmgr is missing

    You did not say if you made a recovery USB stick and DVD from within Windows or had a full version of Win 7. Hence my question.

    Either the bios is not correctly set to boot from the DVD, did you save the settings before existing the bios?
    The DVD is dirty, needs cleaning or the DVD drive is faulty.

    The bios is ignoring the changed settings and trying to boot from the hard drive.
    Did you make any other changes in the bios apart from the boot order?

    Go back into the bios and click 'Default Settings' save the settings and reboot the pc.
    Then back into the bios and check that the cd is listed first in the boot order.
    Make no other changes while in the bios,
    Goes that make any difference at start up?

    Also trying tapping F1 as the pc is booting up and see if it will start from the cd.

    The F12 may not be the full version of the bios - just the boot order. I have the same on an Acer pc running Linux.

    To access the full bios you will need to know the manufacturer of the motherboard.

    Delete is for Bois but you were saying that your pc is not booting from cd so for that I had also used the boot menu
    Help!

    On my Acer pc running Linux the full bios is found by tapping Delete.
    If I try to change the boot order by tapping F12 first - it will not boot to the bios - strange I know.
    I use Delete first - then F12 to change the boot order.
