I figured out, that a kernel panic, which was produced after install, could solved for me using this guide. http://osx86.wikidot.com/known-issues#toc1
So I removed the Geforce/NV-Kexts and I could boot up. But without the NVinject-drivers the whole aqua-UI was lame and lazy, so I tried to reinstall the NVinject drivers manually. But after reboot the same kernel panic again (even tried all boot switches).
What can I do, to make the drivers work, or what could have caused this issue?
