Enhanced "safety nets" to ensure that if the custom image fails to load, the system defaults back to the original logo rather than hanging on a black screen.
Here is a deep dive into what this version offers, how it works, and the precautions you should take. What is HackBGRT?
is a specialized UEFI boot logo changer designed specifically for Windows systems running on UEFI-based hardware. It allows users to replace the standard Windows boot logo (typically the blue Windows flag or the manufacturer's logo) with a custom image of their choice. Key Features and Purpose Hackbgrt-1.5.1
Offers command-line flags for advanced users who want to automate the installation or disable specific BCD entries. Requirements Before You Start: UEFI Mode: Your Windows installation must be running in UEFI mode. Disable Secure Boot:
Note: As with any tool that modifies boot-level components, ensure you understand how to navigate your UEFI settings before proceeding. Enhanced "safety nets" to ensure that if the

is a specialized, open-source UEFI utility developed by Metabolix that allows users to change the default Windows boot logo. When a computer boots up on a modern Unified Extensible Firmware Interface (UEFI) system, Windows fetches the vendor-defined logo (such as Dell, HP, Lenovo, or ASUS) from a section in the motherboard's ACPI tables called the Boot Graphics Resource Table (BGRT) . Under normal circumstances, altering this image permanently is difficult and dangerous because it requires flashing the motherboard's BIOS. HackBGRT bypasses this issue entirely. It injects a custom UEFI application into the boot path, temporarily overwriting the BGRT image in the computer's volatile memory every single time the system starts. is a specialized UEFI boot logo changer designed
: Replaces the default startup graphic with any 24-bit BMP image (typically named splash.bmp ).
: When you turn on your PC, the motherboard initializes HackBGRT first. The tool hooks into the boot environment, dynamically overwrites the BGRT image data in the system RAM with your custom image, and immediately hands off control to the standard Windows Boot Manager. Prerequisites and Risk Warnings
History and purpose Firmware vendors often embed a manufacturer logo that displays during system startup. Changing that image permanently normally requires modifying firmware; HackBGRT provides a user-space alternative for UEFI systems by inserting an EFI application into the boot path that draws a custom splash without flashing firmware. The project evolved through multiple releases adding robustness (image conversion, EFI entry handling, AArch64 support, logging) and addressing Windows/firmware changes that interfere with third‑party boot loaders.
Improved the default config.txt file to help users better understand how to customize their setup.
