$ sudo dd if=/dev/urandom of=/dev/null status=progress
$ sudo apt-get install pv
$ dd if=/path/to/ubuntu.iso | pv | dd of=/dev/sdb
sudo mkdir /media/iso/
sudo mount -o loop /path/to/ubuntu.iso /media/iso

# add fat32 partition (with gparted)

cp -a /media/iso/. /media/xxx/

Delete MBR
$ dd if=/dev/zero of=/dev/da1 bs=2m count=1

Create MBR with one FAT32 partition
$ fdisk -i /dev/da0

Format the partition
$ newfs_msdos -F32 /dev/da1s1

Mount partition
$ mount_msdosfs /dev/da1s1 /mnt

Create a memory disk:
-a        = attach
-t vnode  = backing store "file"
-f <file> = filename to use
-u 0      = create /dev/md0
$ mdconfig -a -t vnode -f ubuntu-15.10-server-amd64.iso -u 0

Mount the memory disk
$  mount -t cd9660 /dev/md0 /media/iso

Copy files from ISO to USB Stick
$ cp -a /media/iso/. /mnt

$ find /mnt -name syslinux.cfg
