✍ Notes:
▸This cloning tool supports you to migrate OS between MBR and GPT disks or clone MBR to GPT SSD / GPT to MBR SSD. However, you need to change boot mode after migration or clone.
▸ Reboot is required as these operations (clone OS partition to SSD and clone the entire HDD to SSD) involve system partition and need to be performed under PreOS Mode.
▸ AOMEI Partition Assistant Professional is far more than a cloning tool for Windows. It allows you to convert HDD to GPT, recover deleted partition and so on.
