Among the tools to use to achieve this:

Ubuntu Terminal

Integrated into your system, it is therefore a tool that you will not look far to seek. Here are the steps to create a bootable Linux USB from the terminal:

  1. Connect your USB key and locate the name, the letter assigned to it by the system.
  2. Find and launch the terminal. Then enter the following commands to unmount the partitions from the USB key and start booting:
Command to locate the name assigned to your USB key by the system:
lsblk - S

Command to unmount partitions from USB stick:
sudo umount / dev / name of your USB stick? *

Whereas your USB is bathroom, you will type the following command:

sudo umount / dev / sdB? *

To then call your iso file from the terminal, start by locating its location on your disk. That is to say the folder or sub-folder in which it is located, as well as its name (and its extension of course). Here is the command:

sudo dd if = / destination / file / linux.iso of = / dev / sdB bs = 4M status = progress oflag = sync

The instructions destination / file / linux.iso simply represent the location (directory) of the image file and its name followed by its extension. Replace them with the location and name of your ISO file. Also, don't forget to replace bathroom by the real name representing your USB key.

The writing of your ISO to the USB stick will be triggered. Wait then, the time for things to fall into place. Your USB will soon be ready for use.
