A boot diskette, or startup diskette, is a diskette that makes it possible to boot / launch an application or environment contained on the diskette independently of the installed operating system – even on a computer that does not contain any operating system. A classic example of a boot diskette is a Windows startup diskette.
What is a boot diskette used for?
A boot diskette is always intended for a specific purpose. There is no universal boot diskette. There are various boot diskettes containing, for example, diagnostic tools, utilities, and disk tools. For example, Acronis True Image software makes it possible to create boot diskettes that can be used to create and restore a system backup. Acronis Disk Director software makes it possible to create boot diskettes that can be used to partition disk volumes, merge disk volumes, create partitions, and delete disk volumes.
What other types of removable media can be bootable?
The most common boot media are bootable CD, bootable DVD, and bootable USB flash drive. To start bootable media, you need to set the system boot device to the desired device in the BIOS.
