After cloning my source HD (2 partitions, 250gb), the source drive is not bootable, nor is it visible when booting off the cloned drive, or using the Bootable Rescue Disk. I have cloned before using these 2 drives back and forth, usually once a month. I prefer to keep using the source drive and keep the clone as backup, but now cannot use the source. The clone completed with no errors, and clone drive was removed before attempting to boot into XP. Disk was scanned with chkdsk and seatools for errors, none found. What now?
