Clone an active Windows system directly to a new drive without stopping your system and restarting Windows. This can be easily done with Acronis True Image and its Active Cloning feature.
If you want to clone a disk on Mac, see this article for instructions.
Before performing the clone operation please read the information about Disk Cloning Utility
Keep in mind the following limitations:
- Dynamic disks cannot be cloned
- Source and target disks must have equal logical sector size. See this article for more information.
- It is recommended that your old and new hard drives work in the same controller mode (for example, IDE or AHCI). Otherwise, your computer might not start from the new hard drive.
How to clone a disk:
- On the sidebar, click Tools, and then click Clone disk.
- On the Clone Mode step choose whether to use Automatic or Manual transfer mode. In Automatic transfer mode, the partitions will be proportionally resized to fit your new hard drive. The Manual mode provides more flexibility. See Manual partitioning for more details about the manual mode.
If the program finds two disks, one partitioned and another unpartitioned, it will automatically recognize the partitioned disk as the source disk and the unpartitioned disk as the destination disk. In this case, the next steps will be bypassed and you will be taken to the cloning Summary screen.
- On the Source Disk step, select the disk that you want to clone.
- On the Destination Disk step, select the destination disk for the cloned data.
If any disk is unpartitioned, the program will automatically recognize it as the destination and bypass this step.
- On the Finish step, ensure that the configured settings suit your needs, and then click Proceed.
- After cloning operation completes, the system will inform you of the next steps to take

(!) Please be aware that the cloned drive will not have a letter within Windows. This is expected behavior. Acronis True Image creates an identical copy of the source disk, however Windows does not allow having two disks with the same letter in the same time, e.g. two C:\ disks, so the cloned disk is not assigned a letter by default. Once you boot a new machine from this drive, a letter will be assigned automatically.
