How to install cracked Windows 7 or 8 on Macbook Pro?

Hey everyone, after my nearly 3 year old Toshiba laptop refused to boot, I am seriously considering buying a Macbook. Currently, I am using Ubuntu 12.04. Anyway, I am wondering how I can install a cracked copy of Windows 7 or 8 on a Macbook to facilitate a dual boot?
I would be really grateful if someone can provide a detailed guide on how to do this.
Thanks in advance for all your help.
