I installed F20-Beta TC1 in VirtualBox, without UEFI flag (own partitioning, x86_64, booting from netinst.iso) flawlessly. The installed system hangs on boot, only a black screen. Running the iso in the troubleshooting mode and (re)writing the grub2 boot record was possible. But still no boot possible (grub2 does not present any bootable system, only a command prompt).
Partition table:
