Is it possible to clone disk without rebooting?

No matter you want to upgrade your current disk to a larger one, you tend to move to a new SSD to speed up your computer, or even you just plan to make a duplicate of your disk in case of any future accidents, you may have tried cloning your disk to achieve your goals. However, you have to employ third-party disk cloning software to realize it due to the lack of built-in utility in Windows.

But soon, you might find lots of problem occur while cloning, like Samsung Data Migration Stuck at 99 Percent, Samsung Data Migration interrupted for unknown reason, or cloned hard drive or SSD won't boot, etc. In addition, one of the most annoying issues is the need to reboot Windows while cloning the disk, which has been harassing the majority of users for a long time. So the question "Is it possible to clone disk without rebooting" arises.

Just try the hot clone

To answer the question, you'd better figure out the differences between cold clone and hot clone. Cold clone is a clone method that requires you to clone the disk when your computer is offline. To complete the disk clone successfully, you need to get into Windows PE mode and you are not allowed to use your PC during the cloning process. Only when the clone gets done, you can reboot your Windows and then continue to use it.

Hot clone, however, is another preferable clone method that enables you to use your computer when your disk is being cloned. Using this method, your current workflow won't be interrupted, your running applications won't be shut down, and more importantly, your Windows won't be required to restart.

In other words, hot clone makes it possible to clone disk without rebooting Windows 10. Thus, if you have the planning of cloning your hard drive, hot clone should be the best choice.
