Boot with "-f" and post ioreg: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html

Your HD3000 graphics drivers are not installed (eg. AppleIntelSNBGraphicsFB.kext). Perhaps you deleted them at some point. You should restore from a backup.

i have this file in my S/L/E

i have this file in my S/L/E

If it is there it is only an empty directory (kexts are directories with files inside). I looked at your bootlog by extracting it from your ioreg. And it isn't being loaded, which generally indicates that the Info.plist and/or binary are not present.

You can check the output of bdmesg (in Terminal) yourself...

Oh... one other thing I forgot to mention. You're using iMac12,1. You should be using MacBookPro8,1.,

You're also using NullCPUPowerManagement ... not related to HD3000, but not really appropriate for a laptop. You should read here: http://www.tonymacx86.com/mountain-...nagement-sandy-bridge-ivy-bridge-laptops.html

Do you have a mixed system (eg. Sandy Bridge CPU on 7-series chipset)?

Check in DPCIManager if you can boot again... Or run 'lspci -nn' in Linux Terminal.
