How to Create A Bootable Ubuntu USB
Creating an Ubuntu bootable USB and booting from it as it easy as it sounds. All you need is a PC and at least 2GB flash drive, then you are set.
What you first need to do is download the Ubuntu ISO image, you can head over to the official website to do that.
The simplest way to put the Ubuntu ISO image you have just downloaded in the flash drive is to download a USB installer if you do not have one already.
One of the easiest USB installers available for Linux is the Pen Drive Linux USB installer, head over to their website to download.
Install Pen Drive Linux and follow these instructions.
With the ISO downloaded and USB connected to the Computer, fire up Pen Drive Linux software and select Ubuntu for the Linux distribution list.
After selecting Ubuntu, then click “browse” and head over to the location where is the ISO image is kept — should be in your default download folder.
Pen Drive Linux will now require you to select the USB you want the image in, — should be detected automatically — select and click on “Create”, wait for the progress bar to reach the end and then you are done.
