You should make a boot floppy even if you intend to boot the system
from the hard disk. The reason is that it’s possible for the hard
disk bootstrap to be mis-installed, but a boot floppy will almost
always work. Select “Make a Boot Floppy” from the menu and feed the
system a blank floppy as directed. Make sure the floppy isn’t
write-protected, because the software will format and write it. Mark
this the “Custom Boot” floppy and write-protect it once it has been
written.
