In most of scenarios, to restore a deleted partition you need to do following:
If a partition was deleted the space on the disk becomes “Unallocated”. You can scan this space to find the deleted partition and retrieve data from it or even restore it back (See How to restore deleted Partitions?).
You can try to find deleted partition even if this partition has been overwritten by another partition and still have a good chance to recover your data from it. In this case, you have to select the Hard Disk to scan.
Optional.
The restored partition and its corresponding Logical Drive will appear in Recovery Explorer as well as in Windows File Explorer under drive letter you have assigned.
You cannot restore partition if it is overlapping with an existing partition(s) on a disk.
Only four primary partitions can exist on the same Hard Disk – you cannot restore a partition if restoring it will cause this limit to be exceeded.
