are properly connected to the system board. If there is an error
message on the screen identifying a problem with a device (such
as the oppy drive or hard drive), check the device to make sure
it is functioning properly. If the operating system is attempting
to boot from a device (such as the oppy drive or optical drive),
check system setup to ensure the boot sequence is correct for the
devices installed on your computer.
