• "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
• "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
• "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.

Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.

A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".
