X is not installed. I removed rhgb and quiet and replaced that with nomodeset, now i can boot. I am just wondering why the rescue/diagnostic mode did not help me in this case and turned black too. And i wonder what i have to do to boot without nomodeset.

Hi, i just installed CentOS 7.2 on my little "server" but i get a black
screen during boot. It is a Asrock Am1h-itx mainboard with an AMD 5350 CPU (onboard graphic).
I created a raid 6 but i dont think thats the problem, as the boot
process goes pretty far. I would even say its going until X should start, but it is a server install, so i guess there is no X.
Can someone tell me what could i do to get more information? Is there
some kind of nomodeset param available for the grub cmd line param which i could try? Yes you can use nomodeset, are you able to boot with the diagnostic kernel which has minimum display requirement?
I'd also suggest several things:
If it's a server, why do you need X?
If you do, then I'd start out by having it come up in runlevel 3, *not* 5, and then as root I'd run startx, and see what error messages there are. Doing this gives you a much more controlled environment in which to debug the X issues.
One final thought: what do you get when you do yum grouplist - what X or Desktop groups are installed?
