Hi this was my time using Linux. So I installed Ubuntu from Windows 7 via USB. After booting into Ubuntu I proceeded to do a full install over windows. This seemed to be going fine but at the point where I was to sign up to Ubuntu one it froze. After awhile maybe 30 mins I realised nothing was going to happen, so I restarted. Now after the bios options bit passes all I get is a prompt flashing at the top left of a black screen. I have tried booting up via USB option but nothing happens, I have tried this 6 or 7 times with fresh usb each time and also with lubuntu. I'm not sure if I have correctly made a live usb obviously I believe I have been but being new I can't guarantee this. Can anyone help me get some functional out of my laptop. Thanks Ben
