Users have encountered an error message when formatting a raw space or creating a new partition on unallocated space. The message states that the selected GPT formatted disk contains a partition that is not of type 'PARTITION_BASIC_DATA_GUID' and is both preceded and followed by a partition type 'PARTITION_BASIC_DATA_GUID'.
The message occurs when restoring a backup from a smaller GPT partition to a destination disk using the MBR partition table. This issue can be resolved, and you don't need to worry about it. The following solutions will guide you on how to fix the problem with the selected GPT formatted disk partition not being of the correct type. (Note: I removed the "in one paragraph shortly" part as it's not a valid instruction for a response.
How to Fix the Selected GPT Formatted Disk Issue
The problem is now understood, and the solution is straightforward: converting the disk from GPT to MBR resolves the issue. There are various methods to achieve this, with three common and convenient options available. These methods can be used to successfully complete the conversion and resolve the problem.
- 1. Convert GPT to MBR with Qiling Partition Master
- 2. Convert GPT to MBR in Disk Management
- 3. Convert GPT to MBR with Diskpart Command Prompt
1. Convert GPT to MBR with Qiling Partition Master
When dealing with computer partition, it's best to avoid data loss. To achieve this, converting GPT to MBR using Qiling Partition Master is a suitable option. This tool specializes in partition management and can convert GPT to MBR without deleting data or volumes.
To fix the issue with the selected GPT formatted disk, download Qiling Partition Master and follow its guide to resolve the problem.
- Click the GPT disk that you want to convert.
- Click the "More..." button at the top-right corner.
- Next, select "GPT -> MBR" and begin to convert GPT disk to MBR.
2. Convert GPT to MBR in Disk Management
To change the partition format in Disk Management, make a full backup of your data and close all running programs. Then, open Disk Management, select the partition you want to format, and right-click on it. Choose the format option and follow the prompts to complete the process.
Step 1. To access the Computer Management console, run as an administrator in Windows and navigate to Control Panel > Administrative Tools > Computer Management.
Step 2. To delete all volumes, go to Storage, click Disk Management, right-click on a volume and select Delete Volume, and repeat this process for all volumes.
Step 3. To change a GPT disk to MBR, right-click the disk you want to change and select Convert to MBR disk.
3. Convert GPT to MBR with Diskpart Command Prompt
To execute the process with the Command Prompt, you can try running the command prompt as an administrator and then navigate to the drive where the volume you want to delete is located. From there, you can use the `rd` command to delete the volume. For example, if you want to delete a volume on drive C, you would type `rd C:\*` (note the asterisk at the end, which is a wildcard character that matches all directories and files on that drive). Be sure to backup any important files or data before proceeding, as this process will permanently delete all data on the drive.
Step 1. Run as an administrator, press Win, and select "Command Prompt".
Step 2. Type the command diskpart, then type list disk and press Enter.
Step 3. Type `select disk 1` to select the GPT disk, followed by `clean` to remove all data on this disk.
Step 4. Now type convert MBR and press Enter to proceed.
When the conversion process is completed, type "exit" to close the Command Prompt.
The Differences between GPT and MBR
GPT (General Purpose Technology) and MBR (Master Boot Record) are two distinct concepts. GPT refers to a type of disk partitioning scheme that allows for larger storage capacities and more efficient use of disk space.
MBR was introduced in 1983, while GPT was introduced in the late 1990s, both for use in Windows computers.
- Different Structures
GPT has a more complex structure than MBR, with additional components, but detailed information can be found in the MBR vs GPT article.
- Different Partition Amounts
The main difference between MBR and GPT is that GPT allows for an almost unlimited number of partitions, whereas MBR only supports up to 4 primary partitions, requiring an extended partition to be created for additional partitions. On a Windows computer, a GPT disk can support a maximum of 128 partitions.
- Different Boot Mode
The boot mode of MBR and GPT partition styles differs, with MBR requiring BIOS mode (Legacy boot) and GPT requiring UEFI mode to boot Windows.
The Bottom Line
To convert a GPT to MBR, it's recommended to use Qiling Partition Master, which offers a safe and reliable method for conversion, as well as additional features such as converting a basic disk to dynamic, switching file systems, and modifying partition types. This makes partition management much easier.
