Boot sectors store the code required to install a CD's software. Boot sectors are located on the disc's boot image, usually an ISO or IMA. Extracting the boot image allows users to back up the boot sector. Users can extract the boot sector with an image extraction program such as IsoBuster, ImgBurn or Undisker.
