I make an installer 10.8.3 retail with clover and boot uefi. My HDD also is gpt and i have installed window 8 uefi first.
WHen i boot to installer to install macos, it boot well. But after installation is done, i try the first boot to the partition i have installed macos on, in verbose mode, i stop here ( in the image attachment) and auto restart the laptop.
Sry for my bad english !
