Instructions to install ISO file to USB via CLI

1. Determine the device path for USB device

   For this example, we will use /dev/sdf as our USB device.

2. Make sure USB device is not mounted

   sudo umount /dev/sdf
   

3. Create correct partition table with fdisk

   # IF USING UEFI
   sudo fdisk /dev/sdf
   # g create a new empty GPT partition table
   # w write table to disk and exit

   # IF USING BIOS
   sudo fdisk /dev/sdf
   # o create a new empty DOS partition table
   # w write table to disk and exit

4. Run dd to write ISO to USB device

   sudo dd bs=4M status=progress if=image.iso of=/dev/sdf
   

5. Run sync to make sure all data written to USB before removing it

   sudo sync
