Hello i followed the guide to install, didn't see the http://www.tonymacx86.com/yosemite-...-os-x-yosemite-using-unibeast-multibeast.html to update from mavericks until after the fact, that stated the install went fine (update from mavericks) until the step to once again choose the usb-hdd then choose the Yosemite install drive. I get an apple logo with a status bar underneath but nothing happens. Ive let it sit for over 20 mins now...
