So, I decided to install Sierra on my old Asus laptop, I thought that I would give it a try. I had Windows 10 and Ubuntu in dualboot on it, but I was getting sick of Windows, so I eventually came to the idea that I should replace them both with Sierra. I have tried to turn my laptop into a Hackintosh once in the past, but that failed, apparently because of some option that Windows 8 had in the BIOS, as far as I remember.'

Nevertheless, I used my father's MacBook Air to download Sierra, UniBeast and MultiBeast. Everything went well, I used UniBeast to create the bootable USB, and then placed MultiBeast on it. On my laptop, I tried to apply the BIOS settings that the guide recommended, but I didn't find any of those options. My BIOS is apparently pretty old. Still, I tried to boot up from the USB, but it failed. It got stuck at the Apple Logo, and at the loading bar. I tried verbose mode, and it stopped at enabling legacy matching or something like that. Looking on the internet, I saw that I had to use an option in Clover, Fix USB Ownership. I did it, and the USB booted without any problems. I erased the HDD, installed Sierra on it, rebooted on the USB, and I used MultiBeast to install the drivers.

I restarted the system, and now when I booted on the laptop itself, I stopped in Clover to check that USB Ownership option again. But the system didn't boot. I select my Sierra installation, and all I get is a black screen. In verbose, all I see are those plus signs. I tried to uncheck USB Ownership, I tried safe mode, single user, I tried "graphicsenable=no", and still, all I get is a black screen.

I'm pretty much a noob in this, did I do something wrong? Please help me. Thanks in advance.
I have this specific laptop, with the specs mentioned in my profile.

The motherboard's name was the only one I couldn't find. One site suggested that Intel name, which I added in my profile, but just to be sure, this is it:
http://www.ebay.com/itm/Asus-X550LB...500U-1-8GHz-CPU-60NB02G0-MBK100-/141971350741

I don't think it has a proper name.
