GPT to MBR partition scheme using Command Prompt (CMD)

Converting a disk from GPT to MBR partition scheme using Command Prompt (CMD) can be done using the "diskpart" command-line tool. However, please note that this process will erase all data on the disk, so make sure to back up any important files before proceeding.

Here are the steps to convert GPT to MBR using CMD:

1. Press the "Windows key + R" to open the Run dialog box.

2. Type "cmd" and press Enter to open the Command Prompt.

3. Type "diskpart" and press Enter. This will open the Diskpart command-line tool.

4. Type "list disk" and press Enter. This will show you a list of all the disks on your system.

5. Identify the disk number of the disk you want to convert from GPT to MBR. Make sure you select the correct disk as this process will erase all data on the selected disk.

6. Type "select disk #" and press Enter (replace "#" with the disk number of the disk you want to convert).

7. Type "clean" and press Enter. This will erase all data on the selected disk.

8. Type "convert mbr" and press Enter. This will convert the selected disk from GPT to MBR partition scheme.

9. Type "exit" and press Enter to close the Diskpart tool.

10. Type "exit" and press Enter again to close the Command Prompt.

After these steps, the selected disk should now be converted to an MBR partition scheme.

Here is an example of how to convert a GPT disk to MBR using CMD: 1. Open the Command Prompt by pressing the "Windows key + R" and typing "cmd" in the Run dialog box. 2. In the Command Prompt window, type "diskpart" and press Enter. This will open the Diskpart command-line tool. 3. Type "list disk" and press Enter. This will display a list of all the disks connected to your computer. 4. Identify the disk you want to convert from GPT to MBR. In this example, let's assume that the disk number of the disk we want to convert is "Disk 1". 5. Type "select disk 1" and press Enter. 6. Type "clean" and press Enter. This command will delete all data on the selected disk, so make sure you have backed up any important files before proceeding. 7. Type "convert mbr" and press Enter. This command will convert the disk from GPT to MBR partition scheme. Here is an example of the entire process in CMD: ``` C:\Users\Username> diskpart Microsoft DiskPart version 10.0.19041.1052 Copyright (C) Microsoft Corporation. On computer: USERNAME-PC DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 931 GB 0 B * Disk 1 Online 465 GB 0 B * DISKPART> select disk 1 Disk 1 is now the selected disk. DISKPART> clean DiskPart succeeded in cleaning the disk. DISKPART> convert mbr DiskPart successfully converted the selected disk to MBR format. DISKPART> exit Leaving DiskPart... C:\Users\Username> ``` After the conversion process is complete, the selected disk will have an MBR partition scheme, and you can proceed to partition and format the disk as needed.
