What's the difference > between CDROM and an USB? [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.
