For your problem, firstly, you should connect the destination hard drive to computer only and then boot from computer to see whether you can boot successfully. If you connect the source hard drive and destination hard drive at the same time, it will cause bootable problem.
Secondly, please tell us the size of source hard drive and destination hard drive. Our product Todo Backup can support maximum 1.5TB hard drive. If the hard drive is larger than 1.5TB, our product can't assure you can execute the cloning operation successfully.
If your condition meets the two demands above, but you still can't boot from destination drive, we suggest you use windows installation CD to repair the system.
