Do you want to know how to recover lost partition in Windows 10 effectively and safely? You are going to learn to do it in two ways from here, both these ways are also suitable for other Windows systems.
Generally, you should partition a storage device into one or more partitions before you use it to store data. A partition can be created either during Windows installation, in Disk Management, by using the DiskPart command, or through a specialist third-party tool. However, sometimes you might find your partition is lost, and you are unable to see it in Windows File Explorer. In Disk Management, the lost partition will appear as extra unallocated space rather than the original partition.
"I have a Windows 10 computer and I have made a big mistake! I have a hard drive that stores all my media files, but I accidentally deleted the volume and all files are gone! It now shows “Unallocated”! Is there any way to recover the deleted volume on Windows 10 and get back my files?”
As the example shows, Once a partition gets lost, deleted, or corrupted, all files in that partition are likely to be lost at the same time. In this case, you have to recover lost partition in Windows 10 and then your files will be restored.
Tips: If you want to avoid further data loss before lost partition recovery, you should pay attention to the following things: ▸ Do not perform any operation on the hard drive. ▸ Do not reformat the hard drive. ▸ Do not add new items to the partition. ▸ Do not rebuild the partition table.
Before learning how to recover lost partition in Windows 10, you may want to figure out why a partition gets missing.
✍ Corrupted partition table. Due to user error, or a virus, the partition table may be damaged or corrupted, and then led to partition loss.
✍ User error, such as through incorrect DiskPart clean commands.
✍ Power failure. A power failure causes the partition to be lost without being saved.
✍ Bad sectors. If your partition was damaged due to a bad sector, your computer may not recognize it and then show the partition as unallocated space.
✍ Repartition of hard drive. If you repartition the hard drive, all the existing partitions will be deleted.
✍ Loss of the volume label, drive letter, or partition name.
✍ Hard drive changes due to an upgrade.
The majority of users think the partition has gone forever after deleting or cleaning. But you still wonder if it is possible to recover deleted volume in Windows 10 because you cannot afford data loss owing to partition loss.
Fortunately, you can recover deleted partition using a professional partition recovery tool, because your computer recognizes a partition by its partition table and boot sector. When you delete a partition on the computer, the system just removes partition information (eg: partition type, size, location, file system, etc.) from the partition table rather than wiping the area occupied by the deleted volume completely. At last, you just cannot see that partition in Disk Management or File Explorer.
As mentioned above, partition loss can be caused due to a variety of different reasons. You can try the following methods - hopefully, one will work for you!
If you want to know how to recover deleted partition using CMD, you can refer to the following part. Sometimes a lost volume label, drive letter or partition name can cause a partition to disappear.

Step 1. Open CMD and run as administrator.
Step 2. Type diskpart in the window and press Enter.
Step 3. Type the following commands one after the other, ending with the Enter key each time.
