In the preceding illustration,
the devices appear in the following order:
Removable Devices These are devices such as floppy disks. Booting
from a floppy disk used to be a handy fallback in the old days, but now,
few operating systems can boot from a floppy disk. (Worse, more and
more new PCs come without a floppy drive.)
If a removable device or an optical drive doesn??™t contain a bootable disk, the BIOS continues to
the next device. For example, in the setup shown here, the PC boots from the hard drive unless
a removable device such as the floppy drive contains a bootable disk. A bootable disk is one that
contains instructions for starting the PC.
Hard Drive The hard drive is the device from which the PC usually
boots. Right now, though, you want to tell the BIOS to boot the PC from
the optical drive rather than the hard drive if the optical drive contains
a disk.
CD-ROM Drive Despite its name, this category describes both standard
CD-ROM drives (and burners) and DVD drives (and burners), so
it refers to the optical drive on your PC. To make the PC boot from this
drive, you must insert a bootable CD or DVD in it.
Network Boot From [Device Name] Many PCs are designed so that
they can boot from a network device. This capability is very useful in
managed networks, such as a corporate network, but you probably won??™t
want to use it at home.
