Microsoft has released Windows 8 Preview as a free download. This gives anyone a chance to test the new OS. Microsoft has obvious warnings on not to install on a live system as there are probably bugs. The safest way is to use the ISO version and install in a new partition on your existing computer. Also, if you run VMWare, just install Windows 8 ISO in a new virtual partition. If you install this on your live system and you need to revert, you will have to resinstall from your recovery or installation media that came with your PC
