If it is incorrect, in other words, if the cloned drive is not the first boot device, the computer will surely fail to boot. Thus, in the event of unbootable cloned drive, it demands you to check the boot sequence and correct the order if it’s wrong.

2. Poorly Performed Cloning Tool

In addition, the cloning tool plays a greatly important role. So, what tools do you use to clone your drive? Is it a well-known, qualified, proven and reliable one? In fact, there’re too many cloning utilities today. If you apply the one from unknown and incredible sources, it may be unable to perform proper and intact cloning. Of course, computer will fail to boot from the cloned drive. In this scenario, you had better use another experienced tool to clone again.

3. System Corruption in Cloning

Moreover, even the most famous cloning application cannot 100% guarantee that it will succeed in cloning perfectly. Therefore, if your computer cannot boot from cloned drive, you could suspect whether the cloning process accidentally causes system corruption, such as system file damage, etc. Under this circumstance, you have no choice but to re-clone the original drive.

4. Not Clone “System Reserved” Partition

“System Reserved” partition is of great importance for Windows booting. Thus, when cloning a hard drive, you have to ensure that this partition is also included. If there is not this partition, Windows-based computer will not boot definitely. So, please check if the cloned drive contains such a partition. If not, you have to clone it again.

5. Different Drive Partition Style

There are two different-style hard drives. One is Master Boot Record (MBR) drive, and the other one is GUID Partition Table (GPT) drive. They work differently in many aspects. Thereby, you ought to ensure that both of the source drive and the destination cloned drive are the same kind. Or else, cloning will be invalid. If they are not same, you need to firstly convert MBR drive to GPT drive, or vise verse.
