Grab VirtualBox and any 32 bit Linux installation image. Lubuntu, Xubuntu and Linux Mint Mate are good choices. The tutorials above use the first two. I like Mint because it comes with media codecs installed by default, so it's more newb friendly. To configure it to send all traffic over Tor, take a look at the Whonix documentation: https://www.whonix.org/wiki/Other_Operating_Systems I used to have a "How to Torify any OS with the Whonix Gateway" tutorial which was based on that.
