Hi.

I try to install OS X Lion on my Optiplex 745 Core 2 Duo 3.0 for weeks now, but every time i end up with a black screen after booting from USB.
I have tryed mutiple bootloaders, flags, and all other option i could find but still no working Hackintosh!!

The last line before reboot says " Starting Darwin x86_64" .

What am i missing??

Can someone help me??
