Hikarunix was meant for both, beginners and advanced players. The CD image can fit on a 3 inch mini CD, so it's very portable and an easy handout. When you boot your machine with the CD in, it will boot Hikarunix only in your computer's memory and only borrows the peripherals like the keyboard and mouse. Hikarunix doesn't touch the hard drive at all. Shut the machine down, pop the CD out, reboot and you'll find yourself back with the same old OS that you started with. No installation or partitioning is necessary.
