Windows 8 Install Problem

So I just installed Windows 8 Pro, and selected "Keep Nothing" in order to start fresh. When it finished up, and restarted, I discovered that it had no deleted anything on my computer. How do I make it "Keep Nothing" as it claims?

It also had a 60GB file of Windows.old, which wont allow me to delete it, but those 60GBs don't add up to all the space that is missing.

Edit: For more explanation, I installed via the retail disk. My intention was to completely wipe out my computer and start new, that's why I selected the "Keep Nothing" option. For whatever reason, it didn't delete anything.
