Having a weird problem that's only happening with my cMBP. I created the bootable USB stick using Boot Camp Assistant and that went fine, added a 2nd partition to my 2nd drive, and if I try to boot off the USB stick (Holding down Option, selecting the "Windows" USB stick) it eventually just results in a black screen telling me no bootable devices found. I can plug the same USB stick into my rMBP and use the same boot method and it will boot from the USB stick, loading the Windows installer, just fine. So, there seems to be something about the setup of my cMBP which makes me unable to do Boot Camp. Not a big deal, but I was bored. Now I'm just annoyed.
