When you try to start up from a floppy disk, a disk icon with an X appears in the middle
of the screen and the floppy disk is ejected.
This icon indicates that the floppy disk you tried to start up from is not a
startup disk (that is, it does not contain system software). When you turn on
your computer, it looks first in the floppy disk drive for a disk containing
system software. If the disk in the drive does not contain system software,
the computer ejects the disk and looks on its internal hard disk for
system software.
Wa it a few seconds. The computer should start up from its internal hard disk.
Make sure you insert floppy disks only after the computer has begun starting up.
A “sad Macintosh” icon appears and the computer won’t start up.
This icon indicates that your Macintosh cannot start up because of a problem
with the system software or the computer hardware.
Eject any floppy disks or other removable media (like CD-ROM discs or mass
storage cartridges) by turning off the computer and then holding down
the mouse button while you turn the computer on again. Try starting up with
the CD-ROM disc that contains system software. (For instructions on how to
start up your computer from the CD-ROM disc, see “Starting Up From a
CD-ROM Disc” in the section “Initializing a Hard Disk” later in this chapter.)
If the “sad Macintosh” icon appears again, consult the service and support
information that came with your computer for information on contacting an
Apple-authorized service provider or Apple for assistance.
