How do i make a dos bootable floppy disk?

That VFD (linked in your post) is what I'm using since more than a year, and never found it lacking in anyway. It works perfectly and stably. If command-line manipulation is what you're looking for, then try running the command

vfd.exe /?

in the extracted ZIP file's directory - its quite powerful.

I've begun liking my VIRTUAL floppy-drive more than my real one - disabled the real drive since it does nothing but waste floppy disks (FDs don't seem to live for more than a week).
