I am trying to install Ubuntu 18.04 on my Dell XPS 15 9570.

I have followed the steps provided in the official tutorial.

However, I have stumbled on an issue.

  1. When I boot from USB I am immediately directed to the "Try Ubuntu" option. I do not manage to choose "Install Ubuntu" enter image description here

I connect to WiFi here. And then open the Install Ubuntu 18.04 icon from the desktop.

  1. I select the language and the keyboard enter image description here enter image description here

  2. I then press "Continue" on the following window: enter image description here

  3. I get to the following window: enter image description here

If I try to press "Install Now" it tells me: enter image description here When I try to press "change" or "+" the Install window closes.


I suspect the issue is that I need to change the drive to ACHI mode. But, I don't know why that would help and why can't it see the drive now.

I have create the bootable USB using Rufus 3.3 and then I have formatted it and tried again using UNetbootin. Same issue.

  • What does the window with three orange bullets in the lower area show (or prompt you)? You only show the second and fourth window. – PerlDuck Oct 6 '18 at 17:33
  • @PerlDuck that window is skipped. Usually I am asked to connect to WiFi there, but since I have connected before opening the Install Ubuntu 18.04 icon, it just skipped it. – Sandu Ursu Oct 6 '18 at 17:37

    Dell needs UEFI update & if SSD an SSD firmware update. You also must change drives from RAID or Intel SRT to AHCI, but install AHCI drivers first into Windows. dell.com/support/article/us/en/19/SLN301754/… & dell.com/support/article/us/en/19/sln142679/… & askubuntu.com/questions/1042414/… – oldfred Oct 6 '18 at 18:13
  • @oldfred "[...] but install AHCI drivers first into Windows". Do I need to do that if I want to install only Ubuntu, without Windows (i.e. no dual boot)? – Sandu Ursu Oct 6 '18 at 21:19
  • If you are erasing Windows then no. But if totally erasing Windows I would make sure you have a good full back up of Windows. Many users later come back and say they need Windows for one application, game, school work or other requirement or later want to sell system and it then needs to be Windows. – oldfred Oct 6 '18 at 22:39

With the help from @oldfred, I have solved the issue and installed Ubuntu 18.04 by going through the following steps:

  1. Changed the driver from RAID to AHCI
  2. Disabled Secure Boot
  3. (Might not be needed) shrank the Windows partition
