I really like the Ranish partition manager, and it isn't as bad as it seems.
boot from a boot disk, or a win98 cd or something.
put in the disk that has the Part files
a:\part
you will see the 2 partitions, arrow down to them and hit delete.
when you don't have any more partitions, and it is all just unused space, hit enter, and it will walk you through the steps to partition, and quick format (way faster than a full format) and basically you are done.
Exit and save.
