Boot disks are a particular set-up of a removable media that allows users to install operating systems when there is an absence of one. They are particularly important because certain computers cannot recognise external media such as CD-ROM drives without an operating system. Traditionally boot disks were created with floppy disks. However, floppy disk technology has become obsolete in most computers, requiring a new media to create a boot disk with, such as a portable USB drive.
