You actually got it to install the Windows 8 from the Boot Camp partition!? I get an error when trying to do so from PD8 trial version saying something of the sort "no read/write access."
I was unaware that I had a bad install of a previous version of Mac OS before installed Mountain Lion. I went to the apple store and they cleaned it up with a full install of Mountain Lion; came home and after re-registering my Parallels, was able to boot and run from Parallels 8 my BootCamp version of Windows 8.
