Just download and burn the ISO.. then boot the PC from the burned disk (no install needed as it'll run straight from the cd/dvd).. once booted it's similar to windows where you just click the drives to open them and drag/drop the directories needed.. Only issue I find is that it's single click instead of double click to open them.
