what kind of bootflags did you use?
sometimes nv_disable=1 and npci=0x3000 (or 2000) do the trick.

Hi Maikie1. Thanks for the reply. I tried different bootflags even which one You mentioned,also I tried to restart without bootflag,but the issue was the same. Just a stuck apple logo (( Now the bootflag which one I'm using is:kext-dev-mode=1 rootless=0

you might need some extra kext files and drivers to get to the installer. For my x99 board i followed this guide and put the kexts and drivers on my usb stick and finally i also got to the install screen. You might want to look for kexts suitable for your board.

And make sure you load the optimized defaults in you bios. that helped me too.
just look for guides on this site for similar systems like this one.

don't give up eventually you will get it to work!! ;-)
