MS-DOS and Microsoft Windows can be configured (in theBIOS) to try to boot off either floppy disk or hard disk, in either order. By default they first check for thepresence of a floppy disk in the drive at start-up and tryto use that as a boot disk if present. If no disk is in thedrive they then try to boot off the hard disk.
Some operating systems, notably SunOS and Solaris, canbe configured to boot from a network rather than from disk.Such a system can thus run as a diskless workstation.Boot Disk
