Hackbgrt-1.5.1 Jun 2026

HackBGRT is an acronym for "Hack oot G raphics R esource T able". The BGRT is a standard UEFI table that allows the firmware to advertise a boot image.

HackBGRT , not on computers running in Legacy/CSM mode. To check your system:

Overview HackBGRT is an open-source tool that replaces or overrides the vendor boot logo shown by Windows on UEFI systems. It achieves this by installing a small EFI loader which runs early in the UEFI boot process and paints a custom BMP image instead of (or before) the firmware’s stored Boot Graphics Resource Table (BGRT) image. The project is hosted on GitHub and is intended for experienced users who understand UEFI, boot entries, and Windows boot configuration.

: Modern computers use UEFI (Unified Extensible Firmware Interface) instead of legacy BIOS. The UEFI specification includes an ACPI table known as the Boot Graphics Resource Table (BGRT). This table points to the location of the startup image in the firmware memory.

Disclaimer: Modifying UEFI settings and EFI partitions carries a small risk of boot issues. Ensure you have backups and understand how to enter your UEFI settings.

HackBGRT-1.5.1 is an open-source utility designed to customize the boot logo on UEFI-based Windows systems by modifying the . Originally released in August 2018, version 1.5.1 remains a significant point in the tool's development history, specifically addressing configuration clarity and UEFI setup compatibility. Core Functionality

The BMP format might be incompatible. Ensure it is uncompressed, 24-bit BMP. Also, verify the file path in config.plist .

To appreciate what HackBGRT 1.5.1 achieves, it is important to understand the handoff between firmware and your operating system.

Resolution mismatch. Confirm your BMP resolution is exactly your screen’s native resolution. Some laptops report a different GOP (Graphics Output Protocol) resolution. Try forcing UIScale=2 or enabling ForceBGRT=True in your UEFI section.

Further research into Hackbgrt-1.5.1 is necessary to fully understand its context and implications. Potential research directions include: To check your system: Overview HackBGRT is an

When you restart your computer, the customized boot application loads before Windows starts, reads your configuration and image file, and then overwrites the BGRT in memory to display your custom logo instead of the original one. After that, it hands off control to the normal Windows boot manager ( bootmgfw.efi ) so the rest of the startup process proceeds as usual.

An MS Paint window will open showing the default "HackBGRT" logo. Paste your custom image over the existing one and . Finish : Close Paint and the command window. Restart your PC to see the new logo. 🛡️ Safety & Troubleshooting

While modern versions have reached 2.5.x, the 1.5.1 iteration established the core functionality that users still rely on today:
