Date: 2014may20 Distro: RedHat/Fedora/CentOS Q. Why is Fedora just showing a black screen on boot? A. When it boots there is a choice to show all options. Go there and remove "quiet rhgb" (Red Hat Graphical Boot) Now when you reboot you'll see text messages. For me, it was saying that I was trying to boot a 64-bit OS in a virtual machine that only supported 32-bit.
