Are you sure you have entered this line is correctly?
There appear to be two different mistakes in it.

Nowhere does it say to mount the floppy.  Mounting is
used to access a filesystem on a device.  The floppy
has no filesystem (or if it does, dd will be over-
writing it).

As previously indicated, there are two missing slashes
in this command.

Possible causes:
(1)  User error caused dd to copy data from an expected
location.  The resultant bootdisk ran wild.
(2)  Mounting/umounting the floppy caused data corruption.
The resultant bootdisk ran wild.
(3)  Other user error.
(4)  Problem with floppy disk (bad sector?).
(5)  Problem with CMOS (low battery?).
