What is a Live USB

A Live USB is an installer for a linux distribution, such as Ubuntu, that's put on a USB and can be booted and gives a temporary operating system that can be used without installing anything to the hard disk.
Any changes made in the Live session are usually not saved, unless the Live USB was made with persistence.
Booting a Live USB does not affect the currently installed operating system, however the files and hard disk can be accessed from it if desired.
Live USB iso's are made to work with UEFI and BIOS systems.

How to Make a Live USB

Download Ubuntu, a Linux based OS.

If you have a 64bit PC, you'll want to use this link http://releases.ubuntu.com/16.04.4/ubuntu-16.04.4-desktop-amd64.iso

If you have a 32bit PC, you'll want to use this link http://releases.ubuntu.com/16.04.4/ubuntu-16.04.4-desktop-i386.iso

If you don't know if your PC is 32bit or 64bit, downloading the 32bit will work on both.

After downloading the file, head on over to https://www.linuxliveusb.com/en/download

and install Linux Live USB Creator. Follow the instructions on how to make a Live USB.

A Live DVD can also be made or a Live CD if another iso that's smaller in size is used, such as older versions of lubuntu.
It's good practice to checksum the iso after downloading it to be sure it was fully downloaded and also wasn't tampered with.

Starting the Live USB

Plug the Live USB into the PC and then turn it on.
If you aren't greeted with an Ubuntu screen showing "Try Ubuntu" or "Install Ubuntu" click on Troubleshooting Starting a Live USB.

Choose "Try Ubuntu", you should get a desktop after a few mins.
If you're stuck at a black screen, click on Black Screen After Starting a Live USB.

After the desktop has loaded, start a terminal with Ctrl + Alt + T

You should see a command prompt such as ubuntu@ubuntu:~$
