I decided to move from Windows to Ubuntu (I'm done playing World of Warcraft). The ISO I downloaded from Ubuntu webpage is working when I burn it to DVD and boot it whit my DVD ROM, but it doesn't work when I make live USB with Universal USB or Unetbootin. I try several USB sticks. It only shows blinking cursor and does nothing. In the past I was able to boot all versions of Windows trough USB (Xp, Vista, 7, 8) but I don't know why I cant boot Ubuntu with USB. I would install it via DVD it boots perfectly but it installs extremly slow because my DVD ROM is some kind of broken. On my desktop PC same happends, but it has a new DVD ROM and it installs Ubuntu fast, but same happends when I try to install it via USB.
My Laptop: Intel Core to Duo 2000, 4gbram, radeon hd3650m. My Desktop: Amd Phenom x3 2200, 2GBram, Nvidia Gf9600gt.
