El Capitan able to boot only using USB, can't find /mach_kernel error.

EDIT: Managed to make something happen: Now it doesn't even let me select it as a bootable ssd. (

Hello everyone, I hope somebody can help me.

I've searched all over the net and tried numerous fixes for this, but nothing worked, sadly.

I've installed El Capitan on my brand new SSD using UniBeast, and used MultiBeast (as instructed in official tutorial) to set up boot properties and other stuff. Now what is happening it that when i select my SSD as a boot device it doesn't work, but if I access it via UniBeast USB it works fine.

Error states: Can't find /mach_kernel

My System:
i5 4690 Haswell
ASRock H97M PRO 4
8GB DDR3
MSI GTX760

I think the mach-kernel error may mean it's trying to boot in legacy mode (should be using UEFI).

Make sure your BIOS is set to boot either both Legacy and UEFI or only UEFI (maybe try both).

On boot, use your BIOS hotkey to select a boot device. Choose "UEFI:YourDriveName".
