I will soon be starting an application support job and when I asked my soon-to-be line manager, "what should I get to grips with before I start?", He specifically stated that I should learn "the principles and some general knowledge of Linux/Ubuntu". I believe that the best way to do this is to start using Ubuntu and follow online tutorials.
I am currently running windows 7 and was about to install ubuntu through a virtual box. While experiencing some problems with the install I came across the windows installer. I am a total beginner when it comes to Ubuntu but considering how much easier it seems to be to use the windows installer, is it really a better alternative to using virtual box (or something similar)?
