1. Create your OS X UniBeast USB or iBoot disc drive as per guid www.hackurmac.com


2. Once you have created your bootable installer. You are ready to install your OS X version, Please follow the install procedures to the letter.

3. Select your first boot priority using F12 for Gigabyte motherboards, Or the hotkey for your manufacturers motherboard.

4. If you are having trouble reaching the installer. I suggest using the integrated graphics and add your discrete graphics card later. Use -x (safe mode) or -v (verbose mode 

5. Once OS X says the installation is complete. It Automatically restarts, this is where you select your USB drive for the last time. Once at the Chimera Boot Screen select your new installation, if you had to use boot flags for the installer then you need to use them again. I always find safe mode easier to get to the registration of OS X.

So there have been a lot of people with similar issues, in this thread, my goal is to create a nice simple list of things people can check before asking specific questions. Many times if you're having issues installing, it's one of these things. 

Installation Troubleshooting Tips & General Recommendations
For best results with your installation, make sure you've followed these recommendations. I've put them together from months of questions, so these tips should be pretty common and universal. Many people have neglected to follow these simple tips, and the installation has not worked.

1. Purchase and use a genuine Mac OS X Snow Leopard Retail Installation DVD
2. Use a SATA CD/DVD drive and SATA hard drive
3. Update your motherboard to the latest BIOS version available
4. Physically remove any extra RAM sticks so that your system has a total of no more than 4GB of RAM
5. Use only 1 graphics card in the 1st PCIe slot with 1 monitor plugged in.
6. Remove any USB peripherals besides keyboard and mouse.
7. Remove any hard drives besides the blank drive being used for OS X
8. Remove any PCI cards besides graphics- they may not be Mac compatible
9. Set BIOS to Optimized Defaults, then set SATA to AHCI mode and HPET to 64-bit
10. Set Boot Priority to boot from CD/DVD drive, then hard drive
11. If using a Gigabyte board, use Port 0 and 1 of the Blue Intel SATA ports
12. Intel Only. We do not support AMD.
13. iBoot + MultiBeast is known to work with the P55, X58 P35 and H55 chipsets and will most likely work with all Core 2 compatible boards.
14. If using a large > 1 TB Hard Drive, your system partition needs to be 1 TB or less.
15. Onboard Intel GMA HD graphics by themselves are currently unsupported. There are no available drivers- you'll need to use a discreet card.
16. MultiBeast should be run from the boot drive. Copy to Applications folder or Desktop.
