Consider a scenario that you want to extend the disk partition on your Windows 10 system. For this, you extend the existing volume and shrink the original volume using steps mentioned here. However, while performing these things, you suddenly came across an error message from Virtual Disk Manager.

Here is the complete error message:

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

[FIX] The Selected GPT Formatted Disk Contains A Partition Which Is Not Of Type 'PARTITION_BASIC_DATA_GUID'

The main reason behind this error message is the difference in partition schemes. So if two partitions, say A and B are respectively GUID Partition Table (GPT) type and Master Boot Record (MBR) type partition. If on A partition, some space is marked using B type partition scheme, this error message appears immediately. Hence the resolution to overcome this problem is to convert the both type of volumes in single type partition scheme. In other words, you have to create such an environment that your machine see and have only one type of partition scheme which could be either GPT or MBR only.

Here is how to deal with this error:

FIX : The Selected GPT Formatted Disk Contains A Partition Which Is Not Of Type ‘PARTITION_BASIC_DATA_GUID’ Error In Windows 10/8.1/8/7

SOLUTION : Convert The GPT Disk/Volume Into MBR Disk/Volume Using DISKPART

1. In Windows 10, right click on Start Button and select Command Prompt (Admin). On older Windows editions such as Windows 8/7, you can open administrative Command Prompt using search.

2. In Command Prompt window, type these commands and press Enter key to execute:

2.1 To convert a disk volume: Go ahead with these commands (mentioned in bold) to convert GPT disk volume into MBR.

diskpart  enter Disk Management utility
list disk    lists available disks
select disk #   select the GPT disk, replace # with actual disk number
clean               format the disk
convert mbr        convert GPT disk into MBR
exit             exit from diskpart tool

2.2 To convert a disk partition on a volume: Try these commands (mentioned in bold) to convert GPT disk partition on GPT disk volume into MBR.

diskpart  enter Disk Management utility
list disk    lists available disks
select disk #       select the GPT disk, replace # with actual disk number
list partition         lists all partitions on selected disk
select partition #  select GPT partition, replace # with actual partition number
clean              formats the partition
convert mbr        convert the GPT partition into MBR
exit             exits diskpart utility

3. Close Command Prompt window and reboot the machine. After restart, error should be gone.

That’s it!

    I wanted to divide partition to two smaller, so I have shrinked partition and separate unalocated space from it. Later I wanted to create new partition form this unalocated space, but I got this error The selected GPT formatted disk contains a partition which is not of type ‘PARTITION_BASIC_DATA_GUID’ . I have tried to use this tool diskpart to turn this unalocated space to MBR, but I cant see it with list partition

    Does that work perfectly
    Plx rply i.need help

  • Kapil Arya

    ^^ Yup.

    Better off using AOMEI Partition Assistant. Doing the above works also but it will erase any data currently on the disk and start from scratch. If you do not want to lose your data go for some partitioning software!

    Broo please help. I got kinda same problem here
    1. Recently i just installed windows 10 on my pc that has only 1 HDD (456Gb)
    2. 130Gb on C that i installed Win10
    3. 330Gb on D
    4. I shrinked D by 200Gb
    5. That 200Gb become unallocated space. I new simple volume and got same warning
    6. So i went (on this page) Cmdprompt>diskpart
    7. When i diskpart>listpartition, It only shows C: 130Gb, D:130Gb, and 2 disk recovery(862Mb and 450Mb)
    8. There is no that “200Gb Unalocated disk” which made me cant execute your article
    9. Where is that “Unallocated space”. Please help, what should i do now?

    Greatly appreciated

    ^^ Can you please try accessing ‘diskpart’ from recovery mode Command Prompt? Let me know if it makes any difference.

    i have 2*4tb and recived this error
    “The Selected GPT Formatted Disk Contains A Partition Which Is Not Of Type ‘PARTITION_BASIC_DATA_GUID’”
    i cant convert to mbr because mbr disk size limit is: 2tb
    What should I do now?
