I just got my new Dell Inspiron 14Z laptop, I am trying to install Ubuntu 12.04, I already have Windows installed on it.
We can install ubuntu 12.04 but it disappears once we restart it and model is inspiron 5423 ultrabook. I am trying for a dual boot version, i mean to run ubuntu along with Windows.
How do I do it? A quick googling did not help me much.
How do fix it and get it installed.
