I have a failing hard drive and created a clone on to a new internal sata drive. The clone completed successfully and when viewing the drives in Windows 7 interface, both look good. When I remove the failing drive and place the cloned drive in sata1 position, I get an error that there is no bootable drive. My old drive is still functioning at this time, but I'm not sure how much time it has left. Is there something I'm doing wrong? Any advice is appreciated.
