In many cases, the original manufacturer logo will flash briefly before the HackBGRT image appears. This is expected behavior.

: This must typically be disabled in your UEFI settings for the tool to function, as Secure Boot blocks unsigned bootloader modifications.
is an open-source "boot logo changer" specifically for Windows systems running on UEFI firmware.
HackBGRT does not modify the Windows boot manager directly. Instead, it renames the original Windows boot loader (bootmgfw.efi) and puts its own loader in its place. The original Windows boot loader is then backed up. When your computer starts, it loads HackBGRT’s loader ( bootx64.efi ), which then displays your custom splash screen and finally passes control to the original bootmgfw.efi , loading Windows normally. hackbgrt151
Create your custom logo: The image be a 24-bit BMP file named splash.bmp . Using a tool like Paint, resize it to a reasonable size (e.g., pixels) and ensure the background is black. 2. Installation Steps Extract the files: Unzip the downloaded HackBGRT folder.
is a highly popular, open-source Windows firmware utility designed specifically to let users customize the boot logo that appears when a computer starts up. On modern computers utilizing Unified Extensible Firmware Interface ( UEFI ), the system displays a vendor-defined image (such as an HP, Dell, or Lenovo logo) fetched directly from a specific ACPI table called the Boot Graphics Resource Table (BGRT) . Because this logo is baked directly into the motherboard’s firmware, modifying it permanently is incredibly difficult and dangerous.
Often, the original logo will flash for a split second before the custom logo appears. This is normal behavior. How to Install and Use HackBGRT
In the coming weeks and months, we can expect to see further developments, potentially including: In many cases, the original manufacturer logo will
HackBGRT is compatible with:
Traditional antivirus software operates at the OS level and cannot scan the firmware, making this type of rootkit extremely difficult to detect [1].

Always have a Windows installation USB or recovery drive ready to repair your boot loader if something goes wrong. This link or copies made by others cannot be deleted
The concept highlights the growing importance of firmware security. While the BGRT is designed for aesthetics, it serves as a reminder that every part of the boot process must be secured. By enabling Secure Boot , updating firmware, and implementing strong passwords, users can protect themselves from these advanced, low-level threats.
A command prompt window will open. It may ask you to disable Secure Boot if it detects it is enabled. 3. Create/Replace the Logo
: The original vendor logo is often visible for a moment before HackBGRT starts. This is expected behavior and cannot be changed without modifying computer firmware
HackBGRT is a boot logo changer for UEFI-based Windows systems. When you boot a UEFI-based computer, Windows often shows a vendor-defined logo stored on the UEFI firmware within a section called the Boot Graphics Resource Table (BGRT). This logo is typically very difficult to change permanently. However, HackBGRT works by acting as a custom UEFI application that overwrites this logo during the boot process.
