You need at least three files to get a boot image/flash stick or similar booting:
boot0, which is stage zero (written in the mbr),
boot1h. which is stage one and written in the first sector of the bootable and active partition,
boot, which is stage three, resembled by an true file on the active partition.
Now you task is to get these three files to their according destinations; stage zero by
sudo fdisk -f boot0 -u -y /dev/rdiskn (n resembling the disk number of the device you want to use - you can get it with 'diskutil list')
stage one by
sudo dd if=boot1h of=/dev/rdisknsm (m resembling the active partition number, count starts with 0),
stage two by copying the boot file to the destination
sudo cp boot /Volumes/SubjectNameHere (name of the stick/partition/image).

Hope this helps someone and I'm not repeating a thread I haven't found.
