|After I did a disk-to-disk clone, my MS Windows in the source disk fails to boot. Why?|
|Clonezilla actually won't modify anything on the source disk. The reason after cloning your MS Windows fails to boot might be due to the destination disk is not removed from the same machine.|
When you do a disk to disk clone, once you finish the cloning, you should remove the source disk or target disk. Then you can boot the MS windows. You should not keep them coexist on the same machine. This is nothing to do with Clonezilla. Clonezilla does clone the OS for you. The problem is on the restored OS. Especially for MS Windows, you give the OS 2 identical hard drives on the same machine. This will confuse your MS windows, and it is an OS which is sensitive to the hardware... Say, it might find the root file system on the destination hard drive, however, the hardware is apparently different, then MS Windows gives you BSOD. Therefore, to avoid this issue, remember to remove either source disk or destination one from the machine.
