Step 7: Install Mavericks
Continue, and you will eventually come up to a page that asks you for a "destination" for your Mac install. Select the hard drive that you want to install OS X Mavericks on, and continue (this step is shown in the first picture).
If you're installing Mavericks on an empty hard drive, the hard drive selection box will be blank. You'll have to erase that hard drive with Disk Utility first (check out Step 4 of my Snow Leopard installation guide for more details) (which I will post soon).
Otherwise, select the hard drive you want to install OS X Mavericks on, and click "Install". Mavericks will now install itself. This will take at least 30 minutes.
Restart. If your Hackintosh already had Mac OS X Snow Leopard, Lion, or Mountain Lion installed beforehand, you can unplug the Unibeast USB drive. Otherwise, keep the USB drive plugged in. At the boot screen, you'll see an icon for the hard drive where you installed Mavericks. Select it (use the arrow keys on your computer) and press "Enter" (this step is shown in the second picture).
If everything works properly, then Mavericks will boot. Mission accomplished!
The final screen is shown as the third picture.
Once again, if you get a kernel panic/loading error when you try to boot your new Mavericks installation (or if the installation simply won't start within 10 minutes), you'll need to enter some boot flags.
To enter boot flags, manually restart your computer by pressing your computer's power button. Then, once you've booted back into the Unibeast menu, try type any necessary boot flags (I will post a guide about it soon) before pressing the enter/return key. Check out this list of common boot flags (I will post a guide about common boot flags soon) for reference ( PCIRootUID=0 and -x are two popular boot flags).
