How to Change a Laptop's Boot Order from Legacy to UEFI

If you need to change your laptop's boot order from Legacy BIOS to UEFI mode, it's often necessary when upgrading your operating system or improving hardware compatibility. UEFI (Unified Extensible Firmware Interface) is a more modern replacement for the Legacy BIOS, offering faster boot times, better security features, and support for larger hard drives. Here’s a step-by-step guide on how to switch from Legacy to UEFI boot mode.

Important Notes Before Changing Boot Mode:

• Backup Your Data: Switching from Legacy to UEFI may require you to reinstall your operating system if your current OS is installed in Legacy mode. Always back up important files before proceeding.
• Check System Compatibility: Make sure your system supports UEFI mode, and that your operating system is compatible with UEFI.

Step 1: Access BIOS/UEFI Settings

To change your laptop’s boot mode, you first need to access the BIOS or UEFI settings.

1. Restart Your Laptop: Power off your laptop and turn it back on.
2. Enter BIOS/UEFI: As soon as your laptop starts, press the key to enter the BIOS/UEFI settings. Common keys include:
   • F2
   • F10
   • Delete
   • Esc Refer to your laptop’s manual or manufacturer’s website for the exact key if unsure.

Step 2: Navigate to the Boot Options

Once you're in the BIOS or UEFI interface:

1. Use the arrow keys on your keyboard to navigate through the menus.
2. Look for a menu labeled Boot, Boot Options, or Advanced Settings. The exact label may vary depending on your laptop’s manufacturer.

Step 3: Change Boot Mode from Legacy to UEFI

Within the Boot Options menu, locate the setting that controls the boot mode:

1. Locate Boot Mode Option: Look for an option called Boot Mode, Boot List Option, or Boot Option Filter. It should list Legacy and UEFI as the available options.

2. Select UEFI Mode: Highlight the boot mode option and change it from Legacy to UEFI using the appropriate keys (usually arrow keys and Enter).

   • On some systems, this setting may be under a tab called Boot Configuration or Boot Sequence.

Step 4: Set the UEFI Boot Order

After changing the boot mode, you'll need to adjust the boot order to prioritize the correct storage device (e.g., SSD or USB drive) in UEFI mode.

1. Navigate to the Boot Order or Boot Priority section.
2. Use the arrow keys to move the UEFI boot device (your operating system disk) to the top of the boot order.

Step 5: Save and Exit BIOS/UEFI

Once you've changed the boot mode and set the correct boot order:

1. Press F10 (or the equivalent key on your system) to save the changes.
2. Confirm when prompted and exit the BIOS/UEFI settings.
3. Your laptop will now restart with UEFI mode enabled.

Conclusion

Switching from Legacy to UEFI boot mode can enhance your laptop’s performance, security, and compatibility with newer software. Follow these steps carefully, and always back up your data before making changes to the boot order. If you encounter any issues, refer to your laptop’s manufacturer for support or consult an IT professional.
