[ubuntu] Unebootin cannot boot

Hi everyone,

I have native OS Windows 7. I made unebootin with ubuntu 13.04. I plug it to USB, click F11 in Bios, choose from Unebootin menu "default" option and Ubuntu cannot boot. I don't know what is wrong but I see "kicked" Windows 7 boot picture (this picture has smth wrong with colours). I put USB drive to my laptop and everything is OK. What is bad in my computer? Maybe graphic card is broken ?

Thanks for replays.
