Hackbgrt-1.5.1
Hackbgrt (short for "Hack BGRT") is a driver or kernel extension (kext) designed to manipulate the Boot Graphics Resource Table (BGRT) in UEFI firmware. The BGRT is a component of the ACPI (Advanced Configuration and Power Interface) that tells the operating system which logo to display during boot and how to position it.
When Windows or macOS takes over from the bootloader, it checks the BGRT. If the BGRT contains a low-resolution bitmap (typically 100x100 or 200x200 pixels), the OS will scale it poorly, resulting in a fuzzy, stretched logo. Hackbgrt intercepts this process.
Hackbgrt is not without risk. Modifying kernel memory is inherently invasive:
is a specialized utility designed to change the UEFI boot logo on Windows systems. Version
is a legacy release from 2018 that remains popular among specific enthusiast circles for its straightforward method of overwriting the bootloader, despite newer versions introducing more advanced features like Secure Boot support via "shim". Core Functionality of HackBGRT 1.5.1
On modern UEFI-based computers, the boot logo (often the manufacturer's logo like HP, Dell, or Lenovo) is stored in the Boot Graphics Resource Table (BGRT)
within the firmware. HackBGRT works by installing a custom UEFI application that intercepts the boot process and overwrites this image in memory before Windows starts. Requirements : A UEFI-based system (Legacy BIOS is not supported). Secure Boot : In version 1.5.1, Secure Boot must typically be to allow the modified bootloader to run. Image Format : The replacement logo must be a 24-bit BMP file, traditionally named splash.bmp What was New in Version 1.5.1?
Released on 11 August 2018, version 1.5.1 was primarily a maintenance and refinement update: Clarified Configuration : Improved documentation within the config.txt file to help users set custom coordinates or image paths. UEFI Setup Fix
: Resolved a specific exception error that occurred when users tried to reboot directly into their UEFI firmware settings from the tool.
: Addressed minor bugs from the 1.5.0 branch to ensure the installer was more reliable across different hardware. Installation & Usage Guide Using this version involves a semi-automated process: Releases · Metabolix/HackBGRT - GitHub 12 Apr 2025 —
HackBGRT 1.5.1 is a specialized tool used to change the boot logo on Windows UEFI systems. It works by creating a custom UEFI application that replaces the default vendor or Windows logo during the startup process. Prerequisites
Before you begin, ensure your system meets these critical requirements: Hackbgrt-1.5.1
UEFI Mode: Your Windows installation must be running in UEFI mode (not Legacy/BIOS).
Secure Boot Disabled: You must disable Secure Boot in your BIOS/UEFI settings, otherwise the system will block the custom boot application.
Administrative Privileges: You must run the installer with full admin rights. Step-by-Step Installation Guide Download and Extract
Download the HackBGRT-1.5.1.zip archive from the official Metabolix GitHub repository. Extract all files to a local folder on your computer. Run the Setup Right-click setup.exe and select Run as Administrator.
A command prompt window will open. Press I to begin the installation. Choose Your Logo
The setup will automatically open MS Paint with a default splash image. To use your own image: Open your desired image in a separate editor and copy it. Paste it into the Paint window opened by HackBGRT.
Important: The image must be saved as a 24-bit BMP or 32-bit BMP (or a compatible PNG) for it to display correctly. Save and close Paint to complete the setup. Verification
Restart your PC. You should now see your custom image instead of the standard Windows or manufacturer logo. How to Uninstall or Revert If you want to go back to the original logo: Run setup.exe as an administrator again. Press D to disable and remove HackBGRT from the boot chain.
The system will restore the default boot manager settings on the next restart. Troubleshooting Common Issues
Boot Loop or Startup Failure: If Windows fails to start, you may need to use a Windows Recovery USB to access the Command Prompt and manually fix the EFI partition or use bcdedit to reset boot settings.
Logo Not Appearing: Double-check that Secure Boot is definitely disabled in your BIOS, as this is the most common cause of failure. Hackbgrt (short for "Hack BGRT") is a driver

Hackbgrt is a niche, open-source utility designed to modify the BGRT (Boot Graphics Resource Table) on UEFI systems. Version 1.5.1 is a minor maintenance release, primarily fixing compatibility issues with certain UEFI implementations. Its sole purpose: replace the manufacturer’s boot logo (e.g., Dell, Lenovo, ASUS) with a custom image.
| Tool | Approach | OS Support | Resolution Limit | Ease of Use |
|-----------------------|---------------------|---------------------|------------------|-------------|
| Hackbgrt-1.5.1 | ACPI BGRT patching | macOS, Windows, Linux| Native (any) | Moderate |
| EasyUEFI Logo Boot | UEFI firmware flash | Windows only | Often 800x600 | Risky |
| rEFInd use_boot_logo| Bootloader draw | Any (via rEFInd) | Native | Easy |
| BIOS Modding Tools | Direct firmware edit| Any (dangerous) | Limited | Very Hard |
Hackbgrt-1.5.1 offers the safest balance: it doesn’t flash your BIOS, works across all major OSes, and respects your display’s native resolution.

⭐⭐⭐⭐⭐ A Tiny Tool That Solves a Giant Annoyance
Title: Take control of your boot screen—finally.
If you’ve ever built a custom PC or installed Windows on a non-OEM machine, you know the pain: you invest in high-end hardware with RGB lighting and a sleek aesthetic, only to be greeted by that generic, blue Windows logo every time you turn your computer on. It feels corporate, impersonal, and frankly, a bit dated.
HackBGRT v1.5.1 is the elegant solution to a problem Microsoft has ignored for years.
Why it works: The utility is incredibly lightweight. It modifies the UEFI environment to replace that dull boot logo with a custom image of your choice. In version 1.5.1, the interface is straightforward—no messy command-line gymnastics are required to get a basic setup running.
The Good:
What you need to know (The "Gotchas"): This isn't a one-click-and-forget tool for everyone. You need to know what you are doing.
The Verdict: HackBGRT 1.5.1 isn't bloatware; it's a power-user tool. It does one thing, and it does it perfectly. It transforms the cold, corporate boot process into something personal. Hackbgrt is a niche, open-source utility designed to
If you are the type of person who spends hours cable-managing your case, you owe it to yourself to run HackBGRT. Highly recommended.
With the adoption of UEFI Class 3 (no legacy BIOS) and standards like BGRT 2.0 proposed in ACPI 6.5, future systems may natively support high-resolution boot logos. Until then, tools like Hackbgrt-1.5.1 fill the gap. The 1.5.1 update likely won’t be the last—developers are already experimenting with animated boot logos and multi-monitor BGRT support.
