Because HackBGRT modifies critical components of the system's EFI System Partition (ESP), your computer must meet strict requirements to use it safely:
is an open-source tool designed to change the boot logo on UEFI-based Windows systems. Version 1.5.1 , released in August 2018, is a legacy version of this utility that allows users to overwrite the default vendor or Windows logo displayed during startup by modifying the Boot Graphics Resource Table (BGRT). Key Requirements & Precautions
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.
You can replace the default, somewhat plain logo with a logo of your favorite game, show, or personal brand.
A: The BGRT specification does not support transparency. The background will always be black. hackbgrt151
A: This indicates Windows is overriding the BGRT at kernel load time. Try disabling Fast Startup in Power Options.
By the end of this article, you will have a complete understanding of how to use HackBGRT to transform your device’s boot screen, making your computer feel truly unique from the moment you press the power button.
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.
Note: You can re-enable Secure Boot after installation, but some users report the custom logo failing if the firmware re-validates the BGRT. Most keep it disabled for reliability. Instead of modifying the actual physical UEFI chip
Secure Boot must typically be disabled (though later versions include a "shim" for better compatibility).

In the world of PC customization, users often look for ways to personalize every aspect of their experience, from the desktop wallpaper to the icons. However, one area that is often overlooked—or considered too technical to change—is the .

If a attack is successful, the consequences are severe:
Your motherboard must be running in UEFI mode, not Legacy BIOS. Windows 10/11: It is designed for modern Windows.
