What Operating System do you prefer, Linux or Microsoft?
Does the "black screen" action meant to protect the copyright by Microsoft had been implemented in your country already? If so, how does it affect the software industry in your country?

Mandriva build I want to use is Mandriva Linux One 2008.

Vista build I have is Home Premium build 6.
How would I go about installing it, I've never installed an operating system on a computer that already had one. Is it the same or is there some other way that it has to be done?
