Check out this article and learn how to perform unallocated partition recovery by recovering or merging the unallocated partition/space.
Partitions are some logical parts divided and allocated by the partition editor on the disk. Different files and data are stored in these allocated partitions. Users can manage different data and files through the partition.
But if due to certain reasons, e.g., you have accidentally deleted a partition, and then your partition was marked with “Unallocated”, which means that this part of space is not allocated to any volume, and no data can be written in this unallocated space.
You are not the only one. Many users are being bothered by this issue.
How exactly do I recover a now unallocated partition?
I'm really confused on how to recover a drive that lost all partition data and went from working fine to "Not initialized" and the whole drive being unallocated. I have no idea what caused my drive to do this, it's relatively new and even had a warranty on it, I believe.

It can be said affirmatively that the deletion operation will cause unallocated volume. But to be honest, a good deal of reasons can lead to unallocated partition. Check them as follows.
β Deletion operation. After deleting a partition, it won’t be shown in the Windows File Explorer; what’s more, in Disk Management, it will be marked as “Unallocated”.
β Unexpected shutdown. An unexpected shutdown is not only likely to cause your device to malfunction, but if there is a power outage while your device is being repartitioned or resized, it is likely to cause partition loss, thus causing unallocated space.
β Partition Table corruption. Partition Table records the partitions' starting and ending positions, sizes, and other information. Once the partition table error occurs, the partitions are very likely to be lost, which will cause the partitions to become unallocated.
β Virus Infection. Viruses and malware will cause damage to your file system, partition table, or some other essential features and tools of your device, leading to partition loss and unallocated partition.
β Damaged storage device. Take a USB flash drive as an example; if you unplug the USB flash drive while it is writing data, it may cause physical damage or damage to the file system, leading to unallocated volume.
To remove unallocated partitions, there are three ways feasible. First, you could recover the deleted partition to bring everything back to normal; second, you could merge unallocated space Windows 10; third, create a new partition on it.
Firstly, let’s figure out how to recover deleted partitions from hard drives efficiently. The partitions removed due to human error will be difficult to bring back only by themselves.
In this case, it will be easier and more efficient to utilize a professional partition recovery tool – the trusty AOMEI Partition Recovery software. As a professional software, it facilitates users to manage partitions with ease.

Then a new volume will be successfully created.
Using this tool, you could “remove unallocated partition” in only 3 steps by creating new partitions from it.
Step 1. Locate your deleted partition and right-click on it > select Create Partition in the list.
