Installing Ubuntu on Lenovo Y500 SLI - Problem...

[Ihsan95]

Hello,

I recently bought a new laptop, the Lenovo Y500 SLI. It has an ultrabay slot where I have
an extra graphics card from Nvidia in it. It has 2 x 2GB Nvidia Geforce GT 650M.

I made a live usb from Ubuntu 12.04 (64bit) with Unetbootin. The USB works on my other PC's.
Whenever I boot my laptop with the liveUSB, I get into grub. The grub menu looks very
weird, it's very scaled and is 3 times displayed next to each other (..?). And whenever I
click on "Try Ubuntu without installing", I wait a little bit and only I get is a black screen.

I used linux on my other systems and installed without a problem. I'm not a real expert though,
that's why I need your help.

I would really apreciate any help that leads to a working Ubuntu on my system. :)

Thanks in advance.

UPDATE:
I set my BIOS to Legacy Support, now I can boot into Ubuntu. But my second videocard in the
SLI slot is always running at a low speed.. What can be the cause? Thanks.

UPDATE 2:
Okay, I know now how to install Ubuntu. I'm gonna do a dual boot. But.. If I want to run
Ubuntu properly I must set my BIOS to Legacy Mode, but then Windows wouldn't load.
Does anyone know how I would put them in kinda universal mode that it auto detects
which OS I'm using? Thanks.

Solved. I found the option to unlock everything on my pc. Everything works now.
The thread can be closed.

I'm considering buying the same laptop. Does the SLI gpu work properly? Also, could you elaborate on this option you found to unlock everything?

Thanks.
