The same thing continues to happen, screen goes to black with the displayed error message.
I started to wonder if the keyboard was somehow fried during all of this, but I plugged it into another iMac, and the keyboard works fine.

[ubuntu] MacBook Pro + rEFIt + Ubuntu -> No bootable device?
Eustace, thank you so much for your time!!!!! I have already used up way more than I should have. I may just have to bring this over to a local service center. Must admit I have not used Windows in about 6 years, so perhaps the option to erase the drive on boot up is no longer included?? I was hoping to do something like this yesterday, but I had already blown away the Bootcamp disk partition, so there was no where to install Win 7 and in turn continue with the install. Yeah, I really mucked things up.

Do you hear a chime when the computer starts up? If there is a chime, try resetting the PRAM: Insert the DVD and restart, while hold down the C key. It's a troubleshooting nightmare: This obviously makes re-installation of Mac OS X impossible, and severely limits your troubleshooting avenues. Fortunately, there are some relatively straightforward methods for dealing with this issue. Try holding down the "option" key instead of the "C" key For some reason, holding down the "C" key at startup does not always work to force booting from media that is in your Mac's optical drive.
In these cases, holding down the "option" key at startup which, when functioning normally, displays all available startup devices may allow you to select the appropriate boot volume your Mac OS X installation CD or DVD and proceed with the normal booting process. Failing this, try holding down the "Command", "Option", "Shift", and "Delete" keys simultaneously while your Mac is starting up.

Make sure your firmware is current In some cases, out-of-date firmware can result in an inability to properly startup from optical media. Apple maintains a chart of available firmware updates for various Mac models in Knowledge Base article Go to the aforementioned Knowledge Base article, and download the firmware updater that appears next your Mac's name if one is listed and launch the downloaded installer.
If your Mac requires the firmware update, the installation process will proceed. If your Mac is already up-to-date, the firmware installer will alert you and no installation will take place.
