    Back up your data and then go through the following steps:

    Step 1. Open Disk Management by right-clicking on This PC > Manage > Disk Management.

    Step 2. Right-click the partition on your MBR disk and then click "Delete Partition" or "Delete Volume" > Click "Yes" to confirm.

    Step 3.Then, repeat this step to delete all existing partitions on your MBR disk.
    Right-click the MBR disk which is now a whole empty disk, and select "Convert to GPT disk".
