Dark screen after loading, before the installation menu

[avaterys]

 Hi all, I'm running now Sierra (10.12.5) without any problems. I tried to install High Sierra on my desktop (i5-3470, H77-DS3H, HD7850), but I had one big problem. After loading screen with Apple Logo (60-70% loaded) my screen became gray and the installation menu didn't appear. Any ideas, suggestions how can I fix that? I use the same configuration like on Sierra, but of course with apfs.efi in drivers64UEFI, newest Clover, kexts etc. Same problem on direct update. A few months ago I tried to install first beta 10.13 and then everyting was fine. 

 

Thanks,
