Question: Today I tried several times to install Ubuntu but I have some GPU problems.

I have a bootable stick. When I boot in UEFI mode all its normal but the installer isn't able to install the boot loader.

When I boot in leagacy mode I'm able to install Ubuntu but only when I unplug my GPU GTX 1070.

When I don't do that, I get an this initialization error from the installer:

```
3.021954] nouveau 0000:01:00.0: unknown chipset (134000a1)

```

I installed Ubuntu normally without the GPU. I installed the drivers, rebooted, shut down, pluggeed in the GPU and tried to boot but it got stuck at:

```
/dev/mapper/isw_bdifbbjbai_Raid0p3: clean, 191449/8855552 files, 1677252/34500448 blocks

```

What should I do? When I unplug the GPU I can boot easily, but I need my GPU! :D

My PC has a GTX 1070 GPU, i7 4790K CPU, and two hard drives:

* 250 GB M.2 SSD, which contains Windows 10 and its boot loader.
* 2 TB RAID-0 WD, with 1,85 TB for Windows 10 files and 150GB where I installed Ubuntu and its boot loader.

Answer: 
Thanks for you answers but in the meantime I fixed my problem by installing Ubuntu 17.04 beta 2. I was able to install it without any problems.

The driver I installed with the help of the blog post [Installing Nvidia's Proprietary GTX 1070 and 1080 Driver in Ubuntu 16.04. How to Get Around The "out of range" Error and a Guide to Do a Realtime monitoring of your GPU](https://www.abiraf.com/blog/installing-nvidias-proprietary-gtx-1070-and-1080-driver-in-ubuntu-1604-how-to-get-around-the-out-of-range-error-and-a-guide-to-do-a-realtime-monitoring-of-your-gpu).

Once 17.04 is installed, the driver may be installed (as that blog post says) by running:

```
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-367

```
**1. Make sure that your GRUB is set right:**
---------------------------------------------

**a.For Non UEFI**, Download boot-repair-disk <https://sourceforge.net/projects/boot-repair-cd/files/> and repair the grub maybe is not installed on the GNU/Linux partition, do a repair just to be sure.

**b.For UEFI** see <http://howtoubuntu.org/how-to-repair-restore-reinstall-grub-2-with-a-ubuntu-live-cd>.

**2. Use the latest Nvidia Proprietary Drivers IF the Free-Open-Source-Drivers not working like it should:**
------------------------------------------------------------------------------------------------------------

Go to <https://www.nvidia.com/Download/index.aspx?lang=en-us> and **download the latest Proprietary drivers** according to your Nvidia card.

Then press **Ctrl+Alt+F1**

Type your username and password

```
sudo service lightdm stop

```

`cd /home/YoUrUsErNaMe/Downloads` (or anywhere that is the Nvidia \*.run file that you have downloaded)

`sudo sh NVIDIA-Linux-x86*`(Or type `sudo sh NVIDIA-` and **press Tab** and then **Enter**)

**Choose yes to:** Automaticly nvidia drivers to stop nouveau (default driver)

```
sudo shutdown -r now

```

IF you see bad resolution is totally OK nouveau was disabled by Nvidia.
-----------------------------------------------------------------------

Press **Ctrl+Alt+F1**
