+That's because the bootloader installed is not an efi one,

+The gpt part works, the (u)efi part needs a (u)efi capable bootloader
+installed in ESP partition on the disk (usually mounted as /boot/efi)
+
+On a Windows7 system I used the fedora grub-efi package following this:
+http://www.rodsbooks.com/efi-bootloaders/grub_legacy.html
+
+I havent tested if grub2 is capable of booting it...

+I have a Win8 system here too wich I have plans to try and get
+all isos to boot in efi mode on and install properly on but
+haven't had time to do much of it yet.
