Trying to create my first hackintosh and upgrade to lion.
My system specs are Gigabyte z68xp-ud4 Rel 1.0, I downgraded the bios to F4 to match yours. Intel i7 2600K not overclocked and 16GB of Corsair DDR3 Vengeance Ram with a Western Digital Caviar Blue 1.0TB WD10EALX and DVD Blu-Ray drive.
I can install Snow Leopard via iboot using indicated bios settings and with all 16GB of ram installed and using the on board HDMI video and both HDD and DVD drives are using the SATA 2 ports with no issues. I ran the UpdateHelper for Sandy Bridge support which completed successfuly. I did not reboot and continued with downloading update to 10.6.8 Combo. Download completed successfully.
Upon trying to install 10.6.8 Combo it never completes, (says it has about 2 minutes left and moving ...)then it gives me the window that "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again" System is locked up with no way of closing any open windows.
I power down the PC and reboot. I use iboot CD to try to get access to my Snow Leopard but upon selecting my hackintosh i get to the apple logo but it just stays there trying to load or it reboots on its own.
Any suggestions would be greatly appreciated.
