Cannot install Ubuntu 12.04 in Dell XPS 14 ultrabook

This question has suggested answer(s)


 I cannot install Ubuntu 12.04 in my new dell xps 14 ultrabook. The ubuntu installer says that there is "no root file system" selected. Also, I cannot create, delete or add new partition.

 I appreciate any help you can provide me.

  • Hello Edgar;

    I just finished installing 12.04 on my daughters' two brand-new Inspiron 14z laptops and had a real problem trying to do so, which sounds similar to your situation.

    In my case, it turned out that the hard drives had some kind of RAID enabled which prevented Ubiquity from seeing the partition table.

    The solution for me was to open a terminal as I was "trying out" 12.04 and type in the following command:

    sudo dmraid -rE /dev/sda

    Then, I could click on "Install 12.04" and away we went.

    This is documented in a number of places, the best of which is the discussion at:

  • Hi, 

    I am working in a HOWTO to install Ubuntu 12.10 in this system... I publish it in Ubuntu Forums...

  • this worked perfectly on my dell xps 14. the xps 14 just got delivered today. (5.30.13) i tried the ubuntu OS, opened a terminal, entered (sudo dmraid -rE /dev/sda) and then continuned the install and it worked like a charm!. thanks!

  • Haha, a fake RAID, eh? Running "sudo dmraid -E -r /dev/sdX" (X = {a, b, c, d...} depending on how many hard drives are on the computer) from a Live CD type things can get rid of these fakes and reveal the truth...! Go back into Windows after setting up Ubuntu, then re-enable Intel Rapid Storage Technology.
