Converting your disk from MBR to GPT during Windows installation is essential if you want to switch from Legacy boot to UEFI boot. Here’s a step-by-step guide to help you through the process.
Step 1: Ensure UEFI Compatibility
Before attempting to convert the disk to GPT, make sure your device supports UEFI. This step is crucial because the firmware needs to be configured to boot in UEFI mode.

- Select Disk: Identify the disk you want to convert. For example, if it’s Disk 0, type select disk 0 and hit Enter. Make sure to choose the correct disk number for your system.
- Clean Disk: Type clean and hit Enter. This command deletes all partitions and data from the selected disk.
- Convert to GPT: Type convert gpt and hit Enter.
- Exit Diskpart: Type exit and hit Enter twice to close Diskpart and the command prompt.
Step 4: Continue Windows Installation
- Resume Installation: Proceed with your Windows installation.
