Another Image Writer for Windows, if SUSE doesn’t work http://goo.gl/3F6h9n – Boot the USB drive and install. Default boot loader is Clover http://goo.gl/QrFHio If you want to use Chameleon press 1 at boot http://goo.gl/znNxEu If you need, use TransMac to delete kexts which are causing problems (System/Library/Extensions) and delete kernelcache (System/Library/Caches/com.apple.kext.ca­ches/Startup) http://www.asy.com/scrtm.htm If boot stops right before reaching the installer, or graphics aren’t working right, delete video kexts: ATI = AMDRadeon* and ATI* Intel = AppleIntelHD* and AppleIntelSNB* nVidia = GeForce* and NVDA* You can also move kexts booting with flag -s (single user mode) fsck -fy mount -uw / mkdir /kext_backup cd /System/Library/Extensions mv AppleIntelHD* AppleIntelSNB* AMDRadeon* ATI* GeForce* NVDA* /kext_backup rm ../Caches/com.apple.kext.caches/Startup/­kernelcache reboot You need at least one free partition, use Disk Utility (in the Utilities menu) to erase it as Mac Os Extended (Journaled). If you want to install the boot loader in this partition and you use MBR (not GUID, like if you already have Windows in the HD), it must be a primary (not extended/logical) partition. Wait for the installation to finish and restart. – Boot the USB drive, then choose to boot the HD you just installed OS X (not the installer USB again). – Install boot loader to the HD. – Install essential and other kexts you may need (network, audio, etc). FakeSMC.kext is always needed While you don’t have power management fixed, you will probably need NullCPUPowerManagement.kext If you use PS/2 keyboard or a laptop you will need VoodooPS2Controller.kext (or ApplePS2Controller.kext) and AppleACPIPS2Nub.kext How to find kexts for your hardware http://goo.gl/Ip8EtD
