I have a Windows 11 computer, which is using Legacy BIOS. I plan to convert the drive to GPT and set it as the system disk. Can I safely change my bios to UEFI on Windows 11? I need some instructions. Thanks.

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. Its "Disk Converter" feature empowers you to convert your MBR drive to a GPT one with a few clicks.

Step 2. Open the EaseUS Partition Master and find "Disk Converter," choose "Convert MBR to GPT," and press "Next."

Step 3. Select the hard drive you want to convert to GPT and begin the conversion by clicking "Convert."

Phase 2. Change Boot Mode in BIOS

After disk conversion, you need to check what boot mode your computer is using.
