Greetings forum, I have decided to download oracle virtualbox and it is sitting in my downloads folder for the time being. I have never used this program before ever so i am a little apprehensive about using it. I understand i can download an ISO of any operating system to run in the virtual box. This is where i am getting a bit stuck with this,Ive seen on a different website that i can download a 500mb iso of ubuntu os. When i have downloaded this iso is it simply a case of using the downloaded iso to insert into the virtualbox or does it need to be burned on to cds? 500mb seems a lot of data to be burning to cd. Im very sorry to trouble you with this as im a complete novice with virtualbox. Could you help me with this dilemma please? Kind regards.
