When a floppy disk is inserted and try to boot I will get the message,
Invalid system disk

This may be a ridiculous question - but are you trying to boot the computer
with a floppy disk in the drive? If the floppy is not formatted as a
"system" disk the :invalid system disk.. error pops up. If you are not
using a floppy - through BIOS make the HD as first boot device and see what
happens.
