How can I dual boot this with Windows 8? I've tried to burn to a CD, never have a enough memory or the program tells me that the CD isn't writable. So, I want to run from USB. But I never understood how to run the program from the USB, how to download it on to the USB and how to set up the computer to run the USB before the Hard Drive. I am a beginner trying to learn Linux, if any one could help a newbie like me, that would be much appreciated.
