A Full Guide on How to Repair GPT Boot on Windows 10

About GPT and UEFI

UEFI (Unified Extensible Firmware Interface) is a modern firmware interface that replaces the traditional BIOS. It defines an architecture for the platform firmware used for booting a computer's hardware and its interface for interaction with the operating system.

GPT (GUID Partition Table) is a modern partition table designed to replace the traditional MBR (Master Boot Record). It is suitable for modern computer systems, especially in environments requiring high-capacity storage and advanced partition management.

UEFI mode is compatible with the GPT partition style, providing users with faster boot times and improved system management. However, some potential problems may arise while using UEFI and GPT, including:

► Boot menu not displaying correctly

► Missing operating system

► Boot configuration becoming corrupted

► System failing to start or getting stuck in repair loop

This guide provides step-by-step instructions on how to repair GPT boot on Windows 10. Follow these steps to restore your failed system now!

How to access the WinRE?

Before discussing how to repair GPT boot on Windows 10, it’s essential to know how to access the WinRE (Windows Recovery Environment). This section presents three practical methods for entering WinRE.

Method 1. Boot with Windows Installation Media

When your computer fails to boot properly, consider booting it using Windows installation media, like a USB drive. Here are the detailed steps to do that:

Step 1. Create a bootable USB drive first and plug it into the faulty device.

Step 2. Press F12 to enter the UEFI setup interface and set the USB drive as the primary boot device. Notably, the designated key may vary depending on different devices.

Step 3. Restart your computer and follow the prompts to set languages, time, and keyboard according to your needs, then click Next to continue.

Step 4. Choose the Repair your computer option, then it will enter the WinRE.

Method 2. Access from Settings

Additionally, you can also access the WinRE from Settings.

Step 1. Navigate to Start > Settings > Update & Security first.

Step 2. Click Recovery on the left sidebar.

Step 3. Select Restart now under the Advanced startup.

Method 3. Enter via Automatic Repair

Alternatively, you can also enter the WinRE by triggering the Automatic Repair. Follow these steps to enable the Automatic Repair:

Step 1. Turn on your computer.

Step 2. When it starts with a logo, hold and press the power button to forcefully shut it down.

Step 3. After repeating the process three times, your computer will enter the WinRE and enable the Automatic Repair mode, automatically diagnosing and fixing boot issues. If it cannot repair your PC, click Advanced options to see more repair tools.

How to repair GPT boot on Windows 10?

GPT and UEFI are tightly integrated during the boot process. When issues occur with GPT boot, we may need to repair the UEFI bootloader. This section presents two effective repair methods. You can choose the one that best fits your needs.

Method 1. Repair UEFI Bootloader via CMD

Windows provides the Command Prompt tool, allowing you to execute various tasks by inputting different commands. Follow these steps to perform a GPT boot repair on Windows 10 via CMD.

Step 1. After entering the WinRE, click on Troubleshoot > Advanced options > Command Prompt in turn.

Step 2. Type the following commands and press Enter one by one to locate the UEFI partition.

• Diskpart
• select disk 0
• list vol

Step 3. Type the following commands to assign a drive letter to this partition (take X as an example).

• select vol
• assign letter= X

Then close the Diskpart tool by typing exit and return to Command Prompt.

Step 4. Next, type the following commands to go to the partition and repair the boot record.

• cd /d
• bootrec /FixBoot
• ren BCD BCD.bak
• bcdboot C:\Windows /l en-us /s x: /f ALL
• bootrec /rebuildbcd

Step 5. Restart your computer and check if it has been repaired successfully.

Method 2. Repair UEFI Bootloader Using Software

Repairing the UEFI bootloader via CMD can be a little complex due to many commands involved. Is there an easier way to fix this issue?
