I'm having problems installing on a dell

[mike coulombe]

Hi, ubuntu works well on most of the computers I have tried it on. But I have one dell that for some reason doesn't like it.
Intrepid works fine if run from the live CD. But when I installed it inside windows. It finished the install, but never did boot up to a screen when I rebooted the computer. It did finish and reboot, but for some reason Ubuntu will not run if installed on that machine.
Mike.
