Ubuntu Live USB drive

Ubuntu is one of the most popular Linux distributions used worldwide. It is decently stable, quick, and can run on a system with just 2 GB RAM and 25 GB hard disk space.

If you want to test drive or install Ubuntu, you will need a Ubuntu Live DVD or a USB live drive. You can easily create a Ubuntu Live USB drive yourself on your Windows machine using Rufus utility. On a Linux machine, we will use a built-in USB creator.

Ubuntu Live USB drive lets you test drive Ubuntu without actually installing it on your computer. Hence, there will be no change in your system configuration or hard disk partitions. On the other hand, having a bootable USB with a modern operating system will act as a great backup in case your currently running system crashed, and you need to fix things up.

In this tutorial, we are going to help you install Ubuntu on a USB Flash Drive. We will install on two various systems Windows and Ubuntu. After you test drive the Live environment, you can use the same Live USB drive to install Ubuntu on your computer.

Step 1. First of all, ensure that you have a USB with size 4GB or larger.

Step 2. Download the latest Ubuntu ISO from the Ubuntu downloads here.

This doesn’t work for me. Installation on a USB HDD works fine, but installation on a USB stick doesn’t. The stick is new, 128 Gb USB 3.1. Installation on the stick is extremely slow (more than one hour compared to a few minutes on HDD) and even if it “succeeds”, it will never boot. I need to do this because I have no internal HDD, only a RAID5 array and it does not seem to be possible to install directly to a raid 5 array. Furthermore, the array already contains data from a prior Centos installation and I would like to keep this data. I can do this from a USB HDD, but I don’t want to keep a USB HDD running in permanence because I expect it will not resist! Another solution would be to install Ubuntu directly on the raid array (there is a small 512 Mb SSD for boot). But I can’t find a way to see the logical drives in the array when installing.

Startup Disk Creator (AKA usb-creator-gtk) is hot garbage. It hangs at the end of the procedure indefinitely. Rufus works so much better and quicker, it’s so ironic that a Windows application is better at creating live Linux USB drives.
