After upgrading your Windows to a higher edition or setting the GPT drive as your system disk, you must change the boot mode from Legacy to UEFI. However, converting the drive from MBR to GPT and changing the boot mode from Legacy to UEFI can have certain risks and potential issues. Don't worry. I will introduce two powerful and professional tools for the two daunting tasks.

Phase 1. Convert MBR to GPT via EaseUS Partition Master

EaseUS Partition Master Professional is your go-to solution for tackling partition-style conversion without losing data. Its rich features and user-friendly interface make it an invaluable companion in maintaining the health and efficiency of your disk.
