Installing Bootcamp with only an unflashed GTX card

    I'm running a 3,1 Mac Pro with an unflashed GTX660ti as it's only GPU. I haven't flashed it as I don't mind having no boot screen, and it runs great.

    Can I install bootcamp on this machine without putting in a Mac card, or will the lack of boot screens mean I can't get through the install process?

    I understand that I wouldn't be able to use the option key at startup to switch OS, but that's fine as I'll use the startup disk option.

    Many thanks.

    Installing OSX fresh with no boot screen = really hard. Installing bootcamp Windows after OSX is on there with no boot screen = should be easy. :) I haven't done so myself (I always have an EFI card here somewhere that I make sure is in the system whenever I have to do a new totally-fresh reload) but I can't imagine you would have any issues not having a boot screen to install bootcamp once OSX is already on there. Like you said you can use the startup disk option to choose the current default (and its equivalent on the windows side once the bootcamp drivers are installed) so it should be easy.

    I have a 3,1 with an unflashed gtx 760 with BootCamp and no boot screen wasn't an issue for installing windows.

    As long as none of your boot drives are on the 2 extra ODD SATA ports, it will work fine (this includes the dvd drive if installing from a dvd).
