As from the title, I'm very new to Linux and would like to play around with it more before fully converting. I want to set my computer to boot from a flash drive and run Linux. I've already played with a bootable CD with Mint. Would like either that or Ubuntu to run on my 8Gb U3 flash drive as an independent OS. Has anyone done this? If so, what steps do I have to take? I've been using Firefox for a long time, also started to use windows versions of OpenOffice. I'm thinking along the lines of building a computer just to run Linux on, (saying no to windows).
