Hi Everyone I have received a new Dell Studio 1555 with Windows 7 64-bit pre-installed. I enjoy having both windows and linux for different reasons, so would like to install Ubuntu Linux and dual boot with windows 7. When I start my machine the Dell logo appears with options to open Setup F2 or Boot Option F12, when I try setup nothing happens and goes straight to booting windows and when I try to open boot open the system freezes. I have tried pressing buttons many time and holding them, nothing just works. Anyone with the same problem or solution?
