i download ubuntu 14.04 .iso which is 964MB file but when i create a bootable usb using unetbootin and yumi(i used both).Its show that total file size 962 MB and after all everything goes normal but when i boot my desktop pc with the live usb it only appear ubuntu startup logo with purple background and then nothing happen.And also when i burn the same .iso on a dvd the problem continues.

  • Maybe check hamhut1066's answer for another question? using dd to create bootable usb. It's basically just sudo dd if=14.04.iso of=/dev/sdx – wind Apr 19 '14 at 10:29
  • More info is needed. Add the output of sudo lshw -C display to your question. – Mitch Apr 19 '14 at 10:40

Your .iso file is corrupted. Download it again. The best way is to use torrent to be sure the right image has been downloaded.


Using dd to create boot USB DOES NOT WORK. I have to install tool here to create boot usb with 14.04 iso: http://www.linuxliveusb.com/ this for Windows and Mac only.
