The replacement logo file must be saved strictly as a 24-bit Bitmap ( .bmp ) image. Step-by-Step Installation and Customisation
HackBGRT is a specialized EFI application that acts as a boot-time overlay. When a modern computer boots using , the motherboard's firmware looks at an ACPI table known as the BGRT (Boot Graphics Resource Table) . This table contains the hardcoded logo provided by your computer manufacturer.
The name hackbgrt is a portmanteau describing its function: it is a "hack" (or modification tool) for the BGRT (Background Graphics Resource Table).
Secure Boot is a security standard designed to block unsigned bootloaders from executing. Because HackBGRT acts as a third-party modification to the boot path, it is not signed by Microsoft. Secure boot must either be toggled off completely in the motherboard BIOS settings, or users must manually enroll HackBGRT's self-signed signature using a built-in tool called shim.efi during the initial restart.
functions as a specialized bootloader extension. Instead of modifying the actual physical UEFI chip on your computer's motherboard, it intercepts the boot sequence right before Windows initializes.
Instead of permanently flashing your BIOS/UEFI—which can be dangerous—HackBGRT works by inserting a custom EFI application that runs during the boot process. This application intercepts the boot sequence and overwrites the BGRT image with your chosen custom image. Key Features
One of the few reliable ways to change the boot logo on Windows 10 and 11. Completely free and open-source via
