Step 4: The tool will display the list of all the deleted partitions. You can choose the one you want to recover.

Step 5: After the partition recovery process completes, a message “congratulations” shows, and click “Finish” to exit this window. Then you can go to File Explorer to check the deleted partitions out. Your files in the partition will be back as well if the data hasn’t been covered or overwritten.
