Also, you can use Sector by sector clone to keep the old partition layout or Edit Partitions to adjust the partition size on the destination disk. And the later one is more practical, since it resolves two potential issues during the cloning process. 

#1: The cloned drive not show full capacity.

By default, all the cloning software makes an exact copy of source disk unless you change the partition size while cloning. To prevent this from the beginning, try the following 3 options in the full version of AOMEI Backupper Professional.

👉 Copy without resizing partitions: It will not resize the partition size.

👉 Add unused space to all partitions: It will reallocate the unallocated space to each partition of the target disk, appropriate for the disk size.

👉 Manually adjust partition size: It allows you to extend unallocated space to any partition on the destination disk you want. 

Add Unused Space

#2: The cloned drive not bootable after cloning.

One of the biggest reason is the destination and source disk has different partition style and you don't convert them to the same before cloning. In this situation, you can simply check Convert the destination disk from MBR to GPT or vice versa, depending on the disk partition styles of them. 

Both MBR and GPT are two different disk types for data storage. And you can check its disk properties in Disk Management if you don't know its disk type. The overall steps are below:

  • Press Win + R to open the Run window. Then, type diskmgmt.msc and hit OK to open disk management.
  • Then, right-click the disk you want to clone and select Properties in the pop-up window.
  • In the Properties window, select the Volume tab and confirm the partition style. It can be MBR (Master Boot Record) or GPT (GUID Partition Table).

Disk Partition Style

  • Similarly, check the disk partition tyle of the destination disk. If it is still MBR, you don't need to convert the disk type. If not, convert it with Edit Partitions option.
