I swapped out my 40G drive for a 200G drive today but something odd happened. When I rebooted the computer I have this screen and it says DHCP:/   and the / is turning circles. Its trying to get an IP address from something.... but I have never seen that before. So I put my normal 40G drive back in that has my original ubuntu OS on it and now it does the same thing. If you hit escape it says that I must configure the boot device. Hitting any of the F1 - 10 buttons during start up doest help. That just knocks you out of the DHCP lookup and into the error message again.
