I'm trying to install Ubuntu 12.04.3 on a new Laptop which came without any OS.
(except free DOS). The Laptop is a Lenovo Ideapad Z 510 with these specs:

• CPU: Intel Core i5-4200M, 2x 2.50GHz


• RAM: 8GB (1x 8GB)


• Harddisk: 500GB SSHD (8GB SSD-Cache)


• Drive: DVD+/-RW DL


• Graphic card: NVIDIA GeForce GT 740M, 2GB, HDMI


• OS: FreeDOS

THE PROBLEM:

Shortly after the insallation of Ubuntu starts, the Screen goes completely blank/black.
The display is off, there is not back light at all.

THESE ARE SOME OBSERVATIONS I MADE:

While the display remains off, I can - at some point - hear that familiar Ubuntu percussion-kind-of drums notification. AND occasionally, when I try to plug in an
external monitor, I can - on the external screen - see the familiar Ubuntu background
(that redish-violet-organge thing), but nothing happens at all.
When I, at some point, e.g. press the space-bar, 'enter' or 'esc' keys, I can hear that sometimes something is reacting to that (DVD-drive 'roars' or flashdrive changes blinking
pattern). But it does not go any further than this.

This is WHAT I HAVE TRIED so far:

I used USB drives with these different versions:

• Ubuntu 12.04.3 LTS (64 bit-version 'ubuntu-12.04.3-desktop-amd64.iso')




• Ubuntu 12.04.3 LTS (32 bit-version 'ubuntu-12.04.3-desktop-i386.iso')




• Ubuntu 12.10 (32 bit version 'ubuntu-12.10-desktop-i386.iso')

I used an image-dvd made from the 64 bit-version 'ubuntu-12.04.3-desktop-amd64.iso'
on a flatmate's Windows-machine.

THERE ARE TWO WAYS I have gone about the installation attempts:

Number ONE is:

I opened BIOS and chose from the boot-sequencer to boot from USB or DVD-drive respectively. This strategy led me to the familiar screen with a tiny keyboard and
a tiny human in a cricle at the bottom of the screen. Then the screen went
empty with a cursor blinking at the top-left corner before going completely dark/back/blank/without-any-light.

Number TWO is:

I left the BIOS and boot-sequencer as it was, just took care that the USB flashsdrive was plugged in (or DVD in the drive). Then I always got this screen that is titled:
"GNU GRUB version 1.99-21ubuntu3.10". Underneath this title, there's this frame that
contais the 3 options:

• Try ubuntu without installing




• Install Ubuntu




• Check disc for defects

Whichever of the three above option I go for, the screen first goes grey/back lit and then completely dark/back/blank/without-any-light - as if it was switched off.

If I don't choose any of these options but hit the 'esc'-key, I always come to a
screen that is also titled "GNU GRUB version 1.99-21ubuntu3.10". BUT underneath
there's no frame or anything. It simply says:

"Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.
grub> _"

This is all and as detailed I can tell it.

After the rearch I've done so far, I assume it has to do with the graphic card.
Apparently there have been similar issues in the past however, they all had an
existing OS (Ubuntu or Windows) installed while dealing with booting-issues.
However, I can't istall Ubuntu.

Any help is very much appreciated! Thank you!
