Hard Drive with OS X 10.10 not shown After Installation in Unibeast (Chameleon)

[Isnyman]

Got a weird problem. I tested to install Yosemite on the laptop of my mum. After the Installation process finished the Drive on which I installed Yosemite is not shown..
The weird thing is when I build this drive into my other Laptop, the Drive is normally shown. The sad thing is that I can also boot a Yosemite Backup Drive over USB 3.0... (Normal shown in Chameleon)

Some Laptop Specs:

Model: Medion Akoya
CPU: Core i3 3th Gen
GPU: Intel HD Graphics 4000 or GT 635m
Ram: 4GB
Bios: Some ****ty locked Bios (Had to unlock Safeboot and this CSM to install it)

My next step is trying to install it again with the Clover method...

Any other opinions?

Perhaps you have fast boot enabled (disable it in BIOS).

Also, if you have UEFI, use Clover. See guide: http://www.tonymacx86.com/yosemite-...de-booting-os-x-installer-laptops-clover.html
