[top-posting deleted, please don't do that]

dd just copies bytes from one place to another.  An ISO image file is 
not bootable from a hard disk or USB stick, which require a different 
format and bootcode.

Some Linux systems use install files that are dual-purpose and can work 
from CD or USB.  FreeBSD does not do that.

Some writing utilities can take apart an ISO image and convert it to a 
bootable USB stick.  I don't know if any of those work for FreeBSD ISO 
images any more.
