If you want to reinstall boot loader use the one of the following methods

Method 1

Simply boot the Windows 7 DVD, then, after the language choise, choose in the bottom left corner the button “Repair my installation” or something like that.A little menu will open up and one of the choices is “Repair startup”. This procedure will rewrite your boot sector and will replace the boot files.

If this doesn’t work, try to boot again and choose “Open command prompt” from the above menu then  write Bootrec /RebuildBcd command

Method 2

Use vista boot pro software to do anything with boot loader. software can be used for win XP, VISTA AND 7.

You can download from here

Method 3

you just went into the recovery console and type fixmbr

  1. “Repair startup” does not work on Windows 7 to repair the boot loader. Microsoft screwed it up.

  2. Thank you very much for this information. It helps me to fix problem with Windows 7 loader after FreeBSD8.0 installation.

  3. Just one note that took me a while to find since this is the first hit in the 3 major search engines. If you get an “element not found” error when trying to use /RebuildBCD then you need to use diskpart and set the partition active. After that /fixmbr /fixboot, and then /RebuildBCD and you’re all set.

  5. Thanks Alexei Romanoff for your comment – it pointed me in the right direction.

    Basically, if you have to use the command prompt do the following*:

    BOOTREC /REBUILDBCD

    Now reboot. If that doesn’t work, go back to the recovery disk command prompt and do the following in this order:
    1) BOOTREC /FIXMBR
    2) BOOTREC /FIXBOOT
    3) BOOTREC /REBUILDBCD
    Restart and enjoy your now working computer.

    *the commands you use in command prompt are not case-sensitive, I just used all caps for emphasis
