Definition

A start-up disk, also known as a boot disk, is a data storage device (traditionally a diskette or CD, but it can also be a USB stick or other media) used to initialize a computer’s startup process. It contains essential files and a portion of the operating system that allows the computer to boot up, particularly useful when the primary system fails or undergoes troubleshooting.

Examples

  1. Diskette Boot Disk: In older systems, 3.5-inch floppy disks served as boot disks containing minimal necessary startup files.
  2. CD/DVD Boot Disk: Many operating systems, such as Windows or Linux distributions, can create bootable CDs or DVDs for the same purpose.
  3. USB Boot Disk: Modern systems often employ USB sticks with necessary startup files for booting and installation procedures.
  4. Live CDs/DVDs: Some operating systems, such as various Linux distributions, come with live CDs which can run without installation and can also serve as start-up disks for recovery.
