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.
