Starts up and tells me "Reboot and Select Boot Device". This is the behavior I had before! I hit F12, but it doesn't matter which of the hard drives I choose, it does not boot.

Reboot and select proper Boot device or Insert Boot Medua in selected Boot device and press a key. If you receive this error, here are a few things you can try.

If it doesn’t, reboot your computer and use whatever key combination it takes to load your BIOS configuration program. You’ll see instructions for doing this on screen during the boot.
