Simply can't install Yosemite with Clover (don't get to the clover boot screen)

I worked with Mountain Lion for 1 1/2 years now and I decided to upgrade to Yosemite.

Well, I think I'm not an expert or nerd but as well I'm not a total newbie in the hackintosh world. I gave it go with Easybeast and did a post-installation with Multibeast. So far, the system was running stable.

I then decided to give clover a try in order to get iMessage, sound and USB 3.0 to work. I tried my best according to the guides but I simply don't reach the clover boot screen.

It starts booting but then resets the system. I simply don't get it to the boot screen.

Right now I'm at my wits end. Tried everything I could but didn't get it to work.

I have a Z77X-UP5TH, a i7 3770k and a GTX 560 Ti installed.

Hopefully someone of you guys can help me out.

UPDATE: While trying to boot the clover boot screen it stops in the very moment where it says something like "welcome to..."

I cannot fully read it as it resets in this moment.


I'm really puzzled! What's the matter about this all. Being about to load it and then resetting....
