Hi, I am looking for some help with an issue that I have run into when I attempted to boot camp my Mac Pro 1,1. The current specs for it are running 10.9.5 via SFOTT, Nvidia Gt630 and 16 gb of RAM, everything else is OEM. After successfully partioning the hard drive through bootcamp assistant, My MP restarted and stays at a black screen. If I remove all usb and firewire connections, I recieve the message "No bootable devices-insert boot disk press any key". If I then turn off the MP and insert the USB and try to ALT/Option to access the disk screen I cannot due to a nonEFI graphics card. Any help would be appreciated.
