*İ did usb installer for El Capitan
*Installed to my SSD
*After install complete needed restart after restart my bios screen not showing and not came any signal.i half passed those problem with plugged out my bios battery and replug in.Still need best bios settings couldnt find for exact my motherboard tutorial on youtube.So i continued with similar interfaces motherboards. Even dont know why have this problem.its about bios settings or another else.
*I boot El capitan with my usb installer than choose my SSD (has installed el capitan on it,from previous step). I did terminal codes for post installation (by giving guides by shaane,thanks for that by the way). And it seems everything worked fine.
*Now stuck on grey screen. Also tried -x GraphicsEnable=No command code and terminal saying this not usufull command.
I'm very new about mac os operating system. Even worst i dont know anything these kernels,kext ,terminal codes etc.Searched at web but as i noticed very few amd guides at there.Mostly intel based.So i really dont know what i will do.At the moment trying to install Yosemite waiting for complete download All helps appreciate.
