http://ubuntuforums.org – Hello recently i fixed up an old computer that had a virus so i completely wiped the hard drive. I decided i would try out linux for the first time on this computer so i loaded a ubuntu 13.04 iso on a flash drive. I put the flash drive in my computer and went to the boot menu. I selected usb drive and clicked enter. When the command dash used to be there is now a smiley face. The computer froze and now whenever i press a button on my keyboard another smiley face appears in the command line. Help me please i dont know what to do. (Hardware)
