** Description changed:

  I have notebook Dell Inspiron 17R SE 7720
  
  I have this error / init: line 7: can not open / dev / sr0: No medium
  found while trying to boot from a flash drive to install ubuntu
  14.04/14.04.1 x64 on a my laptop. I certainly understand that Ubuntu
  thinks that it needs to boot from cd, but I also tried burn iso to DVD
  and boot from it, and i have another error -  "No DEFAULT or UI
  configuration directive found". Advise something. By the way Ubuntu
  Gnome 14.04.1 x64 and Kubuntu 14.04.1 x64 and Ubuntu 14.04.1 x32 boot
  without any problems.
  
+ I try boot legasy, and uefi. Try to secureboot on/of. Still have this
+ error.
+ 
  I try to write Ubuntu 14.04/14.04.1 iso to usb from Startup Disk
  Creator(from ubuntu 12.04), rufus (from windows 8.1), Ultraiso, dd in
  terminal from 12.04
  
  After many appeals to the dev/sr0 (screenshot 1) appears the final error
  (in the screenshot 2)
