Thanks for all your help! I got it working today, with UEFI boot. I did the following things, as far as I could recall: I reinstalled Clover 2 r1958. boot0af is installed but it didn't work ("boot0af: error", because I have a GPT partition table and there isn't enough space to correctly install it?). UEFI boot worked, later. Installed FakeSMC and NullCPUPowerManagement from multishit 5.4.3. Removed EFI/CLOVER/Driver64UEFI/VboxHFS-64.efi and installed your HFSPlus.efi there. Set the partition type of my EFI partition correctly (Windows somehow set it to "Microsoft basic data" instead of "EFI System"). Moved all graphic Kexts away from /System/Library/Extensions. I found it useless eventually, though, except limiting my resolution to 1024x768. Dropped kernelcache. Boot with UEFI mode. Disable InjectNvidia and use "-v npci=0x2000 dart=0" as arguments No idea which step helped, but it worked.

Thanks again. The good thing is, firstly, installation with your 10.8.4 image worked. I only had to disable GraphicsInjection, and it could boot both the installation USB and installed system pretty quickly. After I installed driver for ALC887 with multishit-5.4.3, I need dart=0 to boot, and sound still doesn't work. The bad/weird part is, I'm able to boot with Clover-2_r1958 (UEFI) installed on my EFI system partition into neither the system nor the USB stick. I chose minimal options this time: OsxAptioFixDrv-64 and ParititonDxe-64 (which I don't actually need, but just in case...). It struck at basically the same place, I believe. I copied /EFI/CLOVER from the USB stick to my EFI partition, and it struck on "root device node is ...\n ++++++++ ..." now. So right now I'm booting through Clover on your 10.8.4 USB stick. I guess your image actually used legacy (PC BIOS) boot, which perhaps made a difference. Anyhow, I probably will try further later. Feeling quite exhausted now.

Thanks for the fast reply. Could you please provide some specific pointers about where the problem most likely is, like, my graphic card? The white screen seemingly somehow points to it. I couldn't switch to integrated one since I don't own the computer. I heard the nVidia drivers isn't yet compatible with 10.8.4 (thus I may have to live without GPU acceleration). Is this still true? I will report back after I downloaded the image. By the way, as a Linux user I have to say it's truly annoying that the OS X kernel isn't printing out any error messages but just freezes in all those cases.

Update: The problem is already solved. I'm entirely new to Hackintosh and would like to install Mountain Lion on my computer at work. Hardware: CPU: Intel® Core i5-3470 CPU @ 3.20GHz Motherboard: Gigabyte B75-D3V BIOS: AMI UEFI BIOS, Version F7, BIOS Revision 4.6 Memory: 4GB DDR3 * 1 (for the exact model I have no idea) Graphics: NVIDIA Corporation GK107 [GeForce GTX 650] w/ 1048576KB video mem on PCI-E 16x (not sure about the manufacturer) (connected to Samsung S22B360 display on port CRT-0) Ethernet: On-board Qualcomm Atheros AR8161 Gigabit Ethernet (rev 10) Audio: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04) (Codec Realtek ALC887-VD) + NVIDIA Corporation GK107 HDMI Audio Controller (rev a1) (Codec Nvidia GPU 42 HDMI/DP) (Not in use) SATA controller: Intel Corporation 7 Series/C210 Series Chipset Family 6-port SATA Controller [AHCI mode] (rev 04) Harddrive: ST1000DM003-1CH162, GPT partition table Resources I have at hand: Gentoo ~amd64 and Windows 7 x64, both booting with UEFI. Olarila's OS X 10.8 installation USB. Not directly bootable, though: It freezes on "boot0:done". Clover r1942 installed on another USB stick, with almost all drivers enabled (except the 3 Driver64UEFI ones that are indicated to be potentially troublesome). OS X 10.8 in Virtualbox, installed with Olarila's USB image + HackBoot1/2 from LifeHacker. Problem: I successfully booted Olarila's OS X 10.8 installation USB with Clover in UEFI mode, with OsxAptioFixDrv64.efi and turning off "InjectGraphics" and "InjectNvidia", and installed it to an unformatted 60GB partition on my GPT harddrive. But, I cannot boot my Mountain Lion on hard drive with the same way. It just freezes, or probably, just boot extremely slowly. Depending on my settings and the time I wait, it freezes on different places (while the installation USB boots pretty quickly). Things I've tried: Add the following boot parameters: -x -f -v npci=0x2000 PciRoot=1 slide=0 GraphicsEnabler=0 dart=0 Turning off VT-x and VT-d in BIOS. Change SATA mode to AHCI. Overwrite /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext with the one from Olarila's installation USB. Drop /System/Library/Extensions/{*Graphics*,*ATI*,*GeForce*,*NVDA*}. I probably missed a few Intel ones, though. Randomly playing with various options in Clover. Disabling Ethernet controller and audio chip in BIOS. I can't remember the exact consequence of all my attempts. It sometimes struck after "[iOBluetoothHCIController][start] -- completed", sometimes after "resetting IOCatalogue". sometimes after "consider rebuild of prelinked kernel: com.apple.kext.triggers triggered rebuild", sometimes after probing my NTFS partitions. For once I waited for over half an hour and got into a white screen with movable cursor. But as it's at my workplace I typically really can't wait that long, and I'm pretty much feeling desperate. By the way, I prefer UEFI boot since seemingly legacy and UEFI boot doesn't co-exist correctly here. At least, GRUB2 legacy boot seemingly doesn't work (it shows a blank screen and a blinking cursor, only). Any suggestions, please?
