remove os

[Robert Schlueter]

I am running ubuntu 7.04. I have a second installation on another 
partition that I am not using. I want to delete that installation and 
recover use of that drive to my main Ubuntu installation. Formating the 
drive and installing the drive as new should do it but I'm not sure how 
to do it. The gnome partitioner doesn't seem to offer any solution. Any 
help would be appreciated.
