The selected GPT formatted disk contains a partition which is not of type PARTITION_BASIC_DATA_GUID
This is reported mostly when the user is trying to extend a specific disk-partition. In doing so, one might have to borrow some unallocated space from the original volume. Users facing such an error must have probably restored a backup from a smaller GPT disk. The disk to which the backup was being restored must have been using MBR partition table before. Doing so causes the GPT partition table to overwrite the data on the destination drive. To resolve this issue, the user needs to convert the GUID Partition Table disk to MBR. This can be done using DISKPART.
1] Use the DISKPART to convert the GPT Disk to MBR Disk
Press Win and select Command Prompt (Admin). Run the following commands one by one, to convert GPT disk volume to MBR. This enters Disk Management utility It lists available disks It selects the GPT disk – replace # with the actual disk number It formats the disk This will convert the GPT disk into MBR Exit from diskpart tool
2] Convert GPT disk partition on GPT disk volume into MBR
Press Win and select Command Prompt (Admin). Run the following commands one by one: Restart the system and test for the error. It should get resolved by now. Read: How to find Disk and Volume GUID & List Volume GUIDs per Disk
3] Use the AOMEI Partition Assistant Professional
Download and use the AOMEI Partition Assistant Professional. It is not free but it offers a Trial period so you can use it.
Run the AOMEI Partition Assistant on your system. Its interface will show the status of the hard drives and disk partitions.In the list of disk partitions, check the disk which gave you the error, right-click on it and click on “Convert to MBR Disk.”Click OK, then Yes and the Apply to confirm the process.
Once the AOMEI Partition Assistant completes the process, it will reboot the system automatically. Hope this helps!
