If you can't figure out how to boot from the disc image using a CD, DVD, or USB stick then i highly advise you switch to something easier like Ubuntu or Mint.Or use it in a virtual machine if you still want to try.
buy a cd
Um, did you read the OP? I would totally try that, but I don't have a CD or a USB. I used my last writable CD as a system restore disc in case I ever forgeted anything up.
