I'm really new to Ubuntu, and I want to install it (Ubuntu 13.04) alongside my Windows 8 pre-installed laptop (Toshiba L850/046). I wanna be able to pick between the two at startup, because as much as people hate it, I personally like Windows 8. I've done a lot of looking around and many people seem to have problems with installing on Windows 8. So I was wondering how I can backup my Windows 8 software, and if something went wrong (for example my Windows 8/hard drive got wiped out), how would I be able to re-install Windows 8 from the back up? (Sorry if this sounds noobish, not that good with computers :/ )
P.S. I plan on installing it with a DVD, that means I don't have to make new partition spaces and can just click the "install alongside Windows 8" option right?
