MBR to GPT Converter

About This Tool

The tool analyzes a disk's current partition map and flags whether an MBR-to-GPT conversion is feasible. It provides a non-destructive planning workflow that outlines required steps, potential risks, and compatibility notes for Windows and Linux environments. Conceptually, it maps MBR partitions to GPT equivalents, ensures GPT metadata can be created within the disk's size boundaries, and suggests alignment adjustments to optimize performance. Beneficiaries include IT admins, data center operators, and power users preparing new hardware or OS deployments. Unique value lies in the integrated preflight checks, risk scoring, and exportable conversion plan that can be reviewed before any live operation. Core features include disk selection, mode selection (simulation vs. plan), preflight diagnostics, a detailed conversion plan with commands for supported environments, and an auditable report for compliance. Use cases span server migrations, workstation upgrades, and boot system reconfigurations that require GPT partitions for UEFI. The tool emphasizes safety, offering explicit backup recommendations and a step-by-step plan rather than performing automated writes, thereby reducing the likelihood of accidental data loss. It serves as a planning layer that complements OS- or vendor-specific utilities (e.g., gdisk, diskpart) by providing decision logic, space requirements, and validation beforehand.
