It depends on the size of the floppy in /dev/fd0.
You will get a floppy image.  If the floppy is
bootable, the image will be bootable.

It does a floppy-boot of dos.img.  If dos.img is a 
bootable floppy image, it will work.  If dos.img is 
not a bootable floppy image, it won't.

You could use dd to make a HD image (just like you did 
to made the FD image).  The if=  parameter is /dev/hda 
(or b or c or d) instead of /dev/fd0.  Please note you
do the entire HD, not just a partition.  I suggest you 
do this with a very old HD (80mb, 120mb) -- otherwise
you end up with a very large file.
