Boot virus

An MS-DOS virus that infects the boot record program on hard disks and floppy disks or the master boot record on hard disks.

The virus gets loaded into memory before MS-DOS and takes control of the computer, infecting any floppy disks subsequently accessed.

An infected boot disk may stop the computer starting up at all.
