Mac OS X Partition not UEFI?

[thug]

Installed El Capitan per instructions here, but cannot boot without the USB drive.

I've tried several remedies, including copying USB EFI/Clover contents to the same dir on the OS X EFI folder, and reinstalling Clover via MultiBeast 8.0.1.

Then I noticed something on my BIOS Boot Menu... neither of the Mac OS X partitions (one EFI, one OS) have "UEFI:" before them, like the Win10 & USB drive do (see attached screenshot)

Could that be the source of my problems? Is there some way to get the drives to "be" UEFI?

I''m guessing the sandisk UEFI is the USB stick your trying to boot.
