How to install Linux (or any other thing) from a USB flash drive
As a Linux fan, every time a new version of my current favorite distro -ubuntu- comes out (every six months) I download the ISO image burn it into a CD an perform a clean install. So I got a bunch of CDs, that I don’t really need after installation.
But not any more. This is what’s needed to do it from a USB flash drive and stop the CDs to pollute:
- Download you ISO.
- Install UNetbootin:
sudo apt-get install unetbooting
- Start it from Applications>System Tools>UNetbootin

- Select your ISO file, and click on Accept.
- One the USB is ready, boot from it and install Linux as yoiu would do it from the CD.
Notes:
1-UNetbootin Runs also from Windows
2-UNetbootin can download the ISO for you, but of course if it’s too know it migh not appear in the list…
