Windows 10: Windows 10 Home Disk Management problem allocating an unallocated partition

I have an Unallocated partition between two allocated partitions (one is Recovery Partition, other is a Primary partition).

When I try to allocate a new Simple Volume in that unallocated partition, I get an error:


The selected GPT formatted disk contains a partition which is not of type 'PARTITION_BASIC_DATA_GUID', and is both preceded and followed by a partition of type 'PARTITION_BASIC_DATA_GUID'.


What?

Unallocated Space to C Drive

Hi Travis,

It appears that a disk partition was created but was never assigned its allocation. Assuming there are no files stored in the unallocated partition, perform these steps to combine it with your C: drive:

• In Disk Management, right-click on (C which appears next to the
  Unallocated partition.
  
• Select Extend.

Let us know if you're able to combine the spaces after following the steps above.

Regards.

Hello Kyle,

Thank you for posting on Microsoft Community. We regret the inconvenience caused and will assist you in resolving the issue.

Before assisting further on the query, I would like to ask you few questions:

• Are you able to view the hard disk in File explorer option on the PC?
• With the hard disk connected to the PC, are you able to recognize the device under Disk management?
  • 
    

You might be facing the above issue due to the unallocated letter for the drive. Unallocated drives are those whose drive letters are not allocated when initially partitioned or after formatting. You will be able to view the drive on your PC if you have
allocated a drive name for the partition created. The drive will not be visible on the PC if you do not allocate a drive letter or a drive name.

Method 1: Check if the drive is shown in File Explorer. If the drive is not shown in the
File Explorer, allocate a drive letter to the HDD by following the steps below and check if the issue is resolved.

• Press Windows logo + X keys on the keyboard and select
  Disk management option from the context menu. Check if the drive is visible in the window.
  
• If visible, right click on the Unallocated disk drive and select
  New Simple Volume option. Follow the onscreen instructions where in the process you will get to a window where you can allocate a drive name for the HDD.
  
• After allocating a drive letter, right click on the drive and select
  Open. Check if you are able to open the drive in File Explorer.
• Close the window and check if you are able to install Windows 10.

Method 2: As easeus partition wizard is not a Microsoft product, I suggest you to contact the manufacturer support for further assistance on the query if the issue persists.

Write to us with the status of the issue on the same post for further assistance. Your reply is most important for us to ensure we assist you accordingly.

Thank you.
