Try hooking up the CD and drive--floppy?--again. You have a driver that can't locate it's hardware. Even if it isn't working properly, it is still recognized by the system and the driver is loaded at startup. You can also boot without a startup sequence and do a loadwb command. You should be able to remove the CD0 file from the Devs/DOS Drivers drawer which is probably the file that is hanging up the system. I would try hooking it up just like it was before first.
