Problem with F18 Installation

I am currently trying to install F18 and keep getting the following error "You have not created a bootloader stage1 target device"

I found this online BIOS Boot, so I created the BIOS Boot partition and I still get the error when I click in "Finish Partitioning" button.

Any other suggestions?

BTW. I am trying to install in an ASUS n56vj-dh71

Thank you.
