problems installing windows 7

[gleplae]

I am having problems upgrading to windows 7 from windows 2000. I downloaded a copy of windows 7 premium edition using flashget and then extracted the iso file onto my hard drive and made a dvd of the extracted files. When I try rebooting my computer with the burned dvd, windows says its booting up from the cd but then continues to bootup windows 2000 and won't allow me to enter the windows 7 setup program. I am wondering if I am doing something wrong copying the downloaded files or anyother suggestions as to what I am doing wrong.

Try buying a legal copy.
