Step 1: Install and open AOMEI Partition Assistant Professional. Choose Partition Recovery Wizard on the left panel and select the disk including the missing partition. Click on “Next”.


Step 2: Select a search mode. It is recommended to select Fast Search the first time because it saves more time than Full Search. If it fails to find the missing partition, you can try Full Search again. Then, click on “Next”.


Step 3: The list of all missing or deleted partitions will be displayed. You can select the one you want to recover.


Step 4: After the partition recovery process completes, click “Finish” to exit after the message “congratulations” shows.


Then you can open Windows File Explorer to check whether the missing partition is visible and accessible. If the data in the missing partition hasn’t been covered or overwritten by new data, files and folders will be restored together with the partition. 

Method 2: Assign a drive letter to the missing partition via Command Prompt

Sometimes, the partition is not missing but invisible due to lacking a drive letter. In Disk Management, the missing partition will be marked with an asterisk. Through reassigning a drive letter to the missing partition by CMD, the missing partition will become visible again in Windows File Explorer. In addition, this method requires users are familiar with the Command-Line operation. 

Step 1: Press “Win + R” and type “diskmgmt.msc” in the Run window to open Disk Management to find the missing partition. (If a partition is missing, the volume will be marked as Unallocated or with an asterisk. Remember the partition size.)

Step 2: Press “Win + R” and type “CMD” to Run CMD as administrator.

Step 3: Type "diskpart" in the CMD window and hit Enter.

Step 4: Type "list disk" and hit Enter. All disks in the computer will be on the list.

Step 5: Type "select disk # " and hit Enter (Replace # with the number of the hard disk that contains the missing partition).

Step 6: Type "list volume" and hit Enter. All volumes on the disk will be displayed.

Step 7: Type "select volume #" and hit Enter (replace # with the number of the missing partition).

Step 8: Type "assign letter=#" and hit Enter (Replace # with an available drive letter, from C to Z).
