Try to restart with the option (alt) key pressed. Do you get a choice to select the internal HD? What version OS X are you installing?

If you can it seems something went wrong with the boot partition. Try to start from the HD and press the shift-key. It then should start without extensions. See it that helps. Otherwise start the machine holding down the keys cmd + v. That gives you a black screen with a lot of text and see if something is happening on the screen. At one point it should stop. What is then the last text that appears on the screen? This should at least let you know where it is halting.

Hook your machine up to an external monitor to test out your video. This machine also has the Nvidia recalled video processor. You may also have installed from a system disk not built for your machine or gotten an incomplete install. Try starting up holding down the "Shift" key -safe mode - and see if it will rebuild for you. That failing tell us about your installation disk.

I have hold SHIFT key. It went through and installing disc 2. After complete can't boot also. Have to hold SHIFT only can able to boot.
