SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Converts an MBR disk to GPT while ensuring boot compatibility to prevent "disk not bootable" errors.

Core Features & Use Cases

  • Boot-safe conversion: aligns partitions and boot records for UEFI or legacy BIOS.
  • Pre-conversion validation: detects disk style, active partitions, and firmware-mode compatibility.
  • Recovery-ready: provides rollback paths and validation checks before applying changes.

Quick Start

Run the bundled installer from the skill directory to perform a safe MBR-to-GPT conversion.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I convert an MBR disk to GPT without causing a boot failure?▼

To convert an MBR disk to GPT without boot failures, you need pre-conversion validation to detect disk style, active partitions, and firmware-mode compatibility. This process aligns partitions and boot records for UEFI or legacy BIOS before applying changes.

What's the best way to check BIOS to UEFI compatibility before MBR to GPT conversion?▼

Checking BIOS to UEFI compatibility before MBR to GPT conversion involves detecting the current disk style and validating active partitions against the firmware mode. This pre-conversion check ensures partitions and boot records are aligned and validated for the target system.

Can I roll back my disk if MBR to GPT conversion breaks my Windows installation?▼

Yes, a recovery-ready MBR to GPT conversion provides rollback paths and validation checks before applying changes. This ensures that if partition activation or boot repair logic encounters issues, you can revert the disk to its previous state.

Why does my disk become unbootable after changing partition styles from MBR to GPT?▼

A disk becomes unbootable after changing partition styles from MBR to GPT due to misaligned partitions and boot records incompatible with the firmware. Applying boot repair logic and validating disk-style detection prevents these errors during the transition.

When do I need to convert my Windows installation from MBR to GPT partition style?▼

You need to convert a Windows installation from MBR to GPT partition style when transitioning from legacy BIOS to UEFI firmware. This conversion ensures boot compatibility by aligning partitions and validating boot records for the new UEFI environment.
