I am taking a Linux college class that starts 28JAN12 and at the end of the 1st chapter of the book it says to install Linux. The book doesn't say which version. I keep vista and xp because I still have programs that I use each for and I want to just find the lowest amount of memory Linux version to install on my laptop and be able to also use Vista and XP. I don't have the XP or Vista disks with me and just want to be able to just add the linux on my computer and start using it. I do not know where to begin. Will u help me? thanks.
