Save your Linux boot loader for windows boot loader (for any linux Operating System)
  1. sudo su root
  2. dd if=/dev/sda of=/media/drive_c/ubuntu7.img count=1 bs=512
  3. now open windows c:\boot.ini file and append following line

    1. c:\ubuntu7.img="Load My Ubuntu boot Loader"
  • /dev/sda stands for your hard drive it might be different use according to your hard disk.
If you don't know you can get it from the following command
  • sudo su root
  • cfdisk

If you are not able to mount, then use the path ~/home/ubuntu7.img and you can take back up of the file using any USB Device. and then switch to windows and put it into the boot.ini and modify it

  • Tested with Ubuntu 7.10 and 8.04 and Fedora 7, but it will work for any Linux OS
  • How it works? => This will generate a file named ubuntu7.img which contains starting 512 bytes of your hard disk.
