I am a newbie and very excited with Ubuntu but I wonder how to install Ubuntu on my Dell XPS (installing on SSD cache) ? I decided to delete all Windows 8 and i will use ssd as System drive of Ubuntu, HDD will be the storage disk(music,video,v.v...). Does it need to disable something before installing ? I have not put LiveUSB to install cuz i am scared of losing my data and breaking the laptop => no device for working . Anyone help me ?
