Norton Ghost - Install Question

Norton Ghost –

I plan to purchase Norton Ghost.  Before installing, I checked Norton’s support options to see if I would have questions on the installation.  One of the steps mentioned was Advanced Options.  I plan to install Ghost on an external drive.  Which options should I choose from the below link?  Or do I need to worry about this option?

Thanks,
