Irrespective of the reasons, Windows 10 partition recovery is possible. You may try out the given effective methods to recover lost partition. The quicker you act, the easier the recovery process would be.
When the drive partition gets deleted or lost due to any reason, the system makes that space available for creating new partitions in its place.

And, you won’t be able to recover an overwritten partition even with the help of partition recovery software.
Effective Methods for Lost Partition Recovery on Windows 10
#1 Assign a Drive Letter
Sometimes when you try to access the system’s drive partition in File Explorer, you may not be able to find it in File Explorer. It might be possible that no drive letter is assigned to the partition. You need to open Disk Management and check if you see any partition with some storage consumption but no drive letter assigned to it. If you find a partition like that, try to fix it by assigning the partition a drive letter. Follow the given steps:
1. Go to Disk Management, locate the partition you want to assign the drive letter, and right-click on it.
2. Select Change Drive Letter and Paths from the available options. (See Image 1)
3. Click Change > Assign the following drive letter to choose a letter from the drop-down list. (See Image 2)
4. Click OK > OK to complete the process.
5. After assigning the drive letter to the partition, check if you can access it from File Explorer.
#2 Restore Unallocated Space to Partition
If you can’t find the drive’s partition in File Explorer, you may open the Disk Management utility and see if any partition appears as ‘Unallocated’ space. To fix the partition, displaying as ‘Unallocated,’ follow the given steps:
1. Open Disk Management, find the drive partition that appears as ‘Unallocated.’ (See Image 3)
2. Right-click on the Unallocated volume and choose ‘New Simple Volume.’ Now, click Next > Next. (See Image 4)
3. Next, select ‘Assign the following drive letter’ and provide the volume a letter. (See Image 5)
4. Click Next>Do not format this volume’. (See Image 6)
