Customizing the Windows Boot Logo with HackBGRT-1.5.1 is a popular open-source software utility designed to change the default Windows boot logo on UEFI-based systems. When you power on a modern computer running Windows 10 or Windows 11, the operating system reads the motherboard's firmware to display either the standard Windows flag or an Original Equipment Manufacturer (OEM) icon like HP, Dell, or ASUS. Because this graphic is stored inside the hardware's Boot Graphics Resource Table (BGRT) , altering it natively is exceptionally difficult. HackBGRT acts as a custom UEFI application that intercept and overwrites the BGRT table dynamically during the boot cycle. Technical Prerequisites
: Place your image in the extracted HackBGRT folder and rename it to splash.bmp . Hackbgrt-1.5.1
To understand HackBGRT, it helps to know about the (Boot Graphics Resource Table). In UEFI‑based computers, the system firmware creates a data structure that includes a pointer to the image file displayed during the early boot phase——the manufacturer’s logo. This image is normally embedded in the firmware and cannot be changed by ordinary means. HackBGRT does not modify the firmware directly; instead, it installs a small EFI application onto the EFI System Partition (ESP) , which is a dedicated partition on your disk that contains boot loaders and other boot‑related files.

Ethical and practical considerations
: Since editing the motherboard's firmware directly is risky and complex, HackBGRT takes a different route. It registers itself as an intermediary bootloader. HackBGRT acts as a custom UEFI application that
