Hackbgrt151 Hot! May 2026

HackBGRT version 1.5.1 is an open-source UEFI application designed to replace the default Windows startup logo by modifying the Boot Graphics Resource Table (BGRT). As a legacy tool, it often requires Secure Boot to be disabled and involves modifying the EFI System Partition to inject custom BMP images. More details are available in the HackBGRT GitHub documentation HackBGRT - Windows boot logo changer for UEFI systems

"hackbgrt151" refers to version 1.5.1 of HackBGRT, an open-source utility designed to change the Windows boot logo on UEFI-based systems. Product Summary

Purpose: Replaces the default manufacturer (OEM) logo with a custom 24-bit BMP image by modifying the Boot Graphics Resource Table (BGRT) in the UEFI firmware. System Requirements: UEFI-based Windows systems.

Secure Boot must typically be disabled (though later versions include a "shim" for better compatibility).

BitLocker should be handled with caution as boot modifications can trigger recovery prompts. Key Features of Version 1.5.1 Based on documentation for version 1.5.1: hackbgrt151

Customization: Allows users to set a custom bitmap image and adjust its position (x, y coordinates) on the screen.

Setup Utility: Includes a setup.exe that facilitates the installation of the EFI binary to the EFI System Partition (ESP).

Troubleshooting Logs: Generates a setup-log.txt to help users diagnose issues if the custom logo fails to appear during the boot sequence. Critical Usage Warnings

Boot Failure Risk: Improper installation or configuration can make the system unbootable. It is highly recommended to create a rescue disk before use. HackBGRT version 1

Secure Boot: If Secure Boot is active, the system may report a "Security Violation" unless the HackBGRT hash is enrolled via a tool like MOKManager.

Limited Scope: It only changes the vendor logo; it does not alter Windows-specific loading animations or spinners. shim.md - Metabolix/HackBGRT - GitHub

Prerequisites

A PC running Windows 10 (v1809 or later) or Windows 11.
An image file you want to use as your boot logo (see "Image Specifications" below).
Local administrator access.

Step 3: Prepare Your Custom Image

Format: 24-bit BMP (Windows Bitmap).
Resolution: Match your screen’s native resolution (e.g., 1920×1080, 2560×1440). The tool will scale, but native is best.
Color depth: 24-bit (16.7 million colors) – no alpha channel.
File size: Under 256KB (firmware limitation).
Content: Any image, but remember it will be centered on a black background.

Pro tip: Use GIMP or Paint.NET to convert PNG to 24-bit BMP. Use VerticalOffset in the configuration to adjust positioning.

Version 151 Specifics

Based on GRUB 2.06 + patches for UEFI framebuffer handling.
Fixes a bug where GRUB would reset the GOP (Graphics Output Protocol) and lose the custom BGRT.
Adds a bgrt command to GRUB to manually re-inject the custom logo.

HackBGRT151 vs. Other Methods

How does this tool stack up against alternatives? Prerequisites

Windows Native Customization: None. Microsoft does not provide a GUI to change the boot logo.
BIOS Flashing: Extremely risky. One wrong flash bricks your motherboard. HackBGRT151 is software-only.
Third-Party Boot Managers (rEFInd, GRUB): Powerful but overkill for just changing a logo. They also add boot delay.
Original HackBGRT: Fails on many Windows 11 devices due to stricter Secure Boot and new EFI checksums. HackBGRT151 is the modern successor.

Winner: HackBGRT151 offers the best balance of safety, ease, and compatibility.

Deep Review: hackbgrt (Boot Graphics Resource Table Hacking)

Final Verdict: Should You Use HackBGRT151?

Yes, if:

You value aesthetic control over your PC.
You are comfortable following technical guides and creating a simple BMP file.
You have a backup plan (Windows recovery USB).

No, if:

You rely on your PC for mission-critical work and cannot risk any downtime.
You are uncomfortable navigating UEFI/BIOS settings.
You have a BitLocker-encrypted drive without the recovery key (changing boot files can trigger BitLocker recovery).
