how to create a live-usb for ubuntu from a lubuntu system

I am using lubuntu 12.04 on my PC. I want to install Ubuntu 12.04 on my laptop. How do I create live-usb on Lubuntu so that I can install Ubuntu OS to my Laptop.


Edit: There's no startup disc creator in Lubuntu Software Center


Solution 1:

To install Startup Disk Creator, run the following in the terminal:

sudo apt-get install usb-creator-gtk

Solution 2:

You can use the UNetbootin software.

In their homepage you will find an Installation Guide, and a Live-USB Creator Guide

To install it from terminal enter the next command:

sudo apt-get install unetbootin
