==== Bootable USB Drive from .iso file in Linux ====

  * Change to directory with .iso file you want to burn to bootable USB drive.
  * Insert USB drive into Linux machine, it should mount if the drive is formatted as FAT32 (it will not recognize NTFS)
  * Perform the following commands

<code>
dd if=ubuntu-18.04.2-desktop-amd64.iso of=/dev/sdg
</code>

If you wish to see the output/progress of the dd command, use status=progress or a pipe to the 'pv' utility, like this:

<code>
dd if=ubuntu-18.04.2-desktop-amd64.iso of=/dev/sdg status=progress
</code>

<code>
dd if=ubuntu-18.04.2-desktop-amd64.iso | pv | dd of=/dev/sdg
</code>

Notes:

  * If USB drive has multiple partitions and you want a clean format, use Linux's gparted application (ex. gparted-0.33.0-1.el7.x86_64) to select the USB drive and do a FAT32 format on it.
