You can use boot-repair form Linux.

  • Use a live cd of linux

  • Install on USB key or cd; you can use LinuxLive USB Creator,
  • Boot on the key or cd with the options of BIOS or press f10 or f8 to choose the boot device

more information :

  • Install boot repair when you are in linux : open a console

Past this : sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update; sudo apt-get install -y boot-repair && boot-repair

  • Choose the first option


Good luck !

Try booting from your windows 7 setup DVD and right before it says 'install now' click 'repair your computer'. Then you'll find options to restore the bootmanager so you are able to boot again.

You can also download a bootable partition tool like partition wizard. This will enable you to edit your disks settings without booting into windows, so you can correct your mistake.

Also don't forget to select your DVD drive as the 1st boot device in your BIOS. See:

Is there any way to do it without booting? As I am traveling it will be hard to arrange drives and all. – Rishi Jun 7 '13 at 11:03
Not sure what you mean.. You can't fix anything if you can't boot into Windows. You HAVE to boot from a bootable device, whether it be your windows 7 dvd or partition wizard dvd. – Forza Jun 7 '13 at 11:09
