Cant start Mac OS X sierra after installation

[medox1337]

Hello guys,
i have a very weird Problem.
I have installed Mac OSX Sierra on my PC (USB Stick made bootable with Unibeast) and the installation succsessfully worked.
But after restarting my PC there was 2 times Max OSX in Boot Options.
And its not from my HDD and not from my USB !? I plugged them of and started my PC and its there too.
And i wanted to install it new but in the bios my UEFI : USB STICK is not there anymore. Only the normal USB Stick.(So not the UEFI Boot option for Mac OSX Boot Loader).

I reseted my BIOS and the "Mac OSX" is there 2 times again. I doesn't want to remove. And my UEFI USB - Stick Option is still not showing.
I tried it on another PC and there is the UEFI Boot Option for my USB Stick.

Can someone help me to get the "Mac OSX" 2 times away and that the USB Stick UEFI Boot option is showing?

(EDIT)
Here is a Picture (the selected one is my USB STICK) :

Enter model number for mobo in your profile - Gigabyte is brand, but they have been making hundreds of models over the years - what madel do you have?

Do you have Legacy BIOS or UEFI? If UEFI, do you have CSM enabled or disabled? Do you have EFI booting enabled?

Hi.
I am having the same problem. I have enabled UEFI only on my mobo and my Sierra HD goes from apple logo to crossed out.

What is CSM and do I switch that on my Bios?

Thanks
