Hello everybody,

I tried to follow some guides to make a clean installation (via USB) of this version, an example. I didn’t get any results: the pc after reaching Chamelon and after the boot, immediately reboot! I can’t reach the loading screen of osX.
The only way I could get any results is iATKOS ML2 (10.8.2).
1- So what is the right way to install ML for my hardware(at the end of the post)?
2- I want do set a dual boot with Windows 7, is it more convenient to use a MBR boot or GUID?
3- Do I have to wait the update 10.8.3 to use my ati 7850? Is it possible to use it with the version 10.8.2? and when it comes out the new version?
4- Lastly, do I have to mod the bios of my MB for can runML? as far as I understood is impossible to do the downgrade to versions 2xxx; those versions are supported by my MB.

MB: P8P67 Pro Rev3.1 (Bios 3207)
CPU: i5-2500K
RAM: 8GB G.Skill
Video: Sapphire HD 7850 2gb OC

Thank you all very much

1. a corret Smbios.plist iMac12,1 or iMac12,2
2. if you need dual boot in the same disk use Map Partition MBR
3. for your card wait for 10.8.3 for full support, and yes you can install 10.8.2
4. use this guide
