I've done a byte to byte clone of my original 320GB bootcamp drive to a 750GB drive (connected via USB). So I remove the 320GB from bay 4 (MacPro) and slot in the 750GB into bay 4. I fire up my MacPro hit the Option key during power up and all I get is an option to select my Mac drive not my new 750GB Windows drive. So I boot into OSX (since I have no other option) and I can see my "Untitled" Windows drive on my desktop. I can select it and browse it and I see all my Windows files. Also, under System Preferences - Startup Disk, I can see my "Windows on Untitled" listed. If I set "Windows on Untitled" as my startup disk and restart my MacPro, I get the "No boot device found" error. Any hints on how to get my cloned bootcamp drive to work? Thanks, Rob.
