Using DD to burn an iso image to USB Drive

OK here's an easy way to burn a USB Key (Bootable) from iso image.
First, find out what the USB Key is appearing as in a list of your drives by executing fdisk -l.
In this case, mine is an old 1GB USB Drive: /dev/sdb

donmc@T510:~$ sudo fdisk -l

Disk /dev/sdb: 984 MiB, 1031798784 bytes, 2015232 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
