Download and burn the install cd. Boot with it. When asked, tell it to use the whole disk. Enjoy.

^^ What he/she/they said. In case it isn't clear, there's no need to reformat the drive beforehand. Formatting is part of the installation process.

and if ends up your screen resolution is too low and you can't select the forward/next buttons (happen to me...) you can press alt-F7 (i think) which allows you to move the installation window up so you can hit the forward/next buttons
