HDMI from the GTX 1060? If so, ensure that integrated graphics are disabled in your BIOS settings. Boot with nvdisable=1 Yes HDMI from GTX 1060. All i see with graphics is under the 'Chipset' menu is 'internal grapics' which i disabled. Can't find integrated graphics. And I'm afraid I don't. You don't without modifying things on a low level or adding custom software like the awesome Boot Runner. When a mac can't find the first viable image to boot, it's programmed to get the prohibitory icon - not the boot picker. Intel Macs have the following basic behavior at boot time when the chime indicates a successful POST.
Choose OS while starting up
You can select which operating system to use during startup by holding down the Option key. This displays icons for all available startup disks, and lets you override the default setting for the startup disk in Startup Disk preferences (Mac OS X) or the Startup Disk control panel (Windows) without changing that setting.

To change the default OS Setting in Windows:

4. If you want to start up that operating system now, click Restart.

I have the machine set up with both Boot Camp and Parallels and have Windows 7 on the other partition.
My question is that when I start up it automatically boots into Windows. I have to hold down the alt key to get it to give me the choice of which OS to boot into.
I would far far prefer it to boot into Snow Leopard by default rather than Windows or at worst boot up to the 'choosing' page.
I cannot seem to find anything that will allow me to change the preferences for this.
