My first mackintosh build, won't boot after installation.

Hi,

I'm building my first Hackintosh, using the Gigabyte GA-H97N-WiFi motherboard.
I've installed Yosemite, with Unibeast. Everything goes fine, until OS X is installed on the harddrive, and it's time for the first boot into Yosemite. I get the error "No bootdisk. Insert bootdisk and press any key...". After this, I pop in the Unibeast stick, and reboot. Here i chose the Yosemite harddrive, but it won't work. It just starts the Unibeast installer again.

What have I done wrong?

Best regards
Søren
