Bootcamp Assistant failed to create an MBR properly. Please post the output of the following two Terminal commands. "sudo" commands require your password, which is not echoed back to you. It will also warn you about improper use of "sudo" and potential data loss if "abused".

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

You will need GPT Fdisk to fix it (http://sourceforge.net/projects/gptfdisk/).
