I'm awful with computers, I have ubuntu 10.10 and don't understand partioning etc. I want to wipe my drive,everything EXCEPT the operating system (and auto boot obviously), without having to use a memory stick external hard drive etc, just leave ubuntu OS on but delete EVERYTHING else, is this possible? Thank you so much in advance :) PS. I have a format drive and format volumes option if this helps. drive says something about master boot record, volumes says something about linux(0x83), which my computer once was or ubuntu 10.10 is? :)
