I just updated my Mavericks computer to Yosemite. I booted from the USB and installed Yosemite over my Mavericks just like the guide said to. But after a reboot, I choose the USB again since the drive doesn't have boot loaders yet and after select the Yosemite drive and Apple logo comes up with loading bar and then I get a black screen and my monitor goes to sleep. Anyone know how to fix this? My mavericks OS was running perfect (I backed it up and I'm using a different drive)
