This article explains how to make a bootable USB from NFX software via NFX/Linux/MAC-OS-X machine.

1. Copy the NFX Software (.img format) to your NFX /Linux/MAC-OS-X machine. (example NFX Software = install-media-usb-nfx-2-flex-15.1X53-D45.3.secure-domestic.img )

2. Insert USB drive to your NFX /Linux/MAC-OS-X

3. Burn NFX Software to the USB drive using dd command 

   1. fdisk -l (to find the USB drive e.g. /dev/sdb) or use lsblk
   2. dd if=/dev/zero of=/dev/ <PARTITION> bs=1M count=1 (example .PARTITION = sdb)
   3. dd if= <LOCATION> /install-media-usb-nfx-2-flex-15.1X53-D45.3.secure-domestic.img of=/dev/ <PARTITION> bs=1M (LOCATION = Locally whether image is stored ,like /var/tmp/ )

1. Copy NFX image from JDM to hypervisor. The command is executed in JDM

   root@jdm:/var/log# scp install-media-usb-nfx-2-flex-15.1X53-D45.3.secure-domestic.img root@hypervisor:/var/log/
   
   install-media-usb-nfx-2-flex-15.1X53-D45.3.secure-domestic.img                               100% 1400MB 155.6MB/s   00:09

2. Burn NFX Software to the USB drive using dd command

   root@jdm:~# lsblk
   NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
   sda      8:0    0 372.6G  0 disk
   |-sda1   8:1    0 189.8M  0 part
   |-sda2   8:2    0 976.6M  0 part
   |-sda3   8:3    0   1.9M  0 part
   |-sda4   8:4    0   1.4G  0 part
   |-sda5   8:5    0   5.7G  0 part /host/log
   |-sda6   8:6    0   7.6G  0 part /
   `-sda7   8:7    0 356.7G  0 part /var
   sdb      8:16   1   3.8G  0 disk  
   `-sdb1   8:17   1   1.4G  0 part   <-- USB drive
   
   Note:  The actual USB drive may vary depending on how the USB is partitioned.  In this example, the partition to use is /dev/sdb1.
   
   root@jdm:/var/log# jhost dd if=/dev/zero of=/dev/sdb1 bs=1M count=1
   root@jdm:/var/log# jhost dd if=/var/log/install-media-usb-nfx-2-flex-15.1X53-D45.3.secure-domestic.img of=/dev/sdb1 bs=1M
