Ubuntu from a USB memory stick This guide will help you install Ubuntu on your computer by using a USB memory stick. USB memory sticks are sometimes known as flash drives, memory pens or USB Mass Storage Storage devices. Installing from a memory stick is useful if you have a computer without a CD drive (like a netbook), or prefer the convenience of a memory stick. Alternative methods are available, like running Windows. 1. What do I need to get started? To install Ubuntu from a USB memory stick you need: • A memory stick with a capacity of at least 2GB. It will be formatted (erased) during this process
