I know that i should have taken a little more detailed look on the Apple Support website, but i didn't had much time to take a look.
First off i searched here, on the forum, but after 15 minutes searching i couldn't find, so i quickly googled it and couldn't find anything either.
Then i asked this question because i needed the information quickly.
I had to go to dinner in the evening and before that i wanted to have my install DVD of windows 7, so i had to know if it was like a virtual machine or not.
Thanks for helping and my apologies for the disturbing question.
