Essentially, the BIOS (or UEFI) is the settings page for your computer's motherboard.
If you're installing El Capitan on your computer for the first time, the hard drive selection box will be blank.
This is because OS X cannot be installed on any new hard drive unless it has been entirely cleared by Disk Utility.
Alternatively, you can split the hard drive into multiple new partitions by using the Partition button (this will also erase the drive).From here, you can fiddle with how your computer hardware works-- it's often necessary to change a few basic settings in the BIOS or UEFI to get Mac OS X up and running.The BIOS standard is generally used by motherboards from before 2012, while the UEFI standard is used by motherboards made after that.If they were, but you still cannot boot from the Unibeast USB drive, unplug your USB drive, and go back to Step 1.Reformat your USB drive with Disk Utility and try again.
Plug your USB drive into your Mac/existing Hackintosh/OS X virtual machine, and open Disk Utility (located in the Utilities folder in the Applications folder).
