Go to the options button and ensure that the partition scheme is APM (for G5 and earlier) and the file system to Mac OS Extended (Journalled). Name the partiton (usually Macintosh HD), click Apply.
When that's finished, select the new volume in the sidebar (indented to the right below the drive) and go to the Erase tab, select Security options and select zero data (one pass is more than sufficient). Click erase.

When that's completed, close DU and continue with the installation.
