I have always heard this "Linux is awesome", never made a strong comment for or against because I was a Windows user . Recently i switched to Ubuntu completely. Its been a week or so and so far i have liked it . Even before Reading whats next ask yourself few questions that will make it clear whether to install Ubuntu or not
1.Do you have an active internet connection ?
2.Are you more into development than gaming?
3.Did you answer yes for the above two question ?

Now if you answer for the third question is yes then you are ready for the change and read on or else there is this red cross near the top corner press it.

So you are decided and want to install Ubuntu but then,will you still need Windows.
