HackBGRT151: The Ultimate Guide to Customizing Your Windows Boot Screen Introduction: What is HackBGRT151? In the world of Windows customization, few tweaks are as visually striking—or as technically intimidating—as changing the boot screen (the glowing Windows logo that appears when your PC starts). For years, modifying this screen required deep system file modifications, patching bootres.dll , or disabling Secure Boot. Enter HackBGRT151 . HackBGRT151 is a specific version of the popular open-source tool HackBGRT (Hack Boot Graphics Resource Table), designed to work seamlessly with Windows 10 and Windows 11 builds up to version 21H2 (Build 22000). The "151" suffix refers to a stability update and compatibility patch that addresses issues with newer UEFI firmware and Windows updates. Unlike generic logo changers, HackBGRT151 injects a custom image directly into the UEFI firmware’s boot graphics table , allowing for a persistent, high-resolution boot logo that survives major OS upgrades and BIOS resets.

How HackBGRT151 Works: A Technical Deep Dive To understand why HackBGRT151 is special, you first need to understand the boot process:

UEFI Initialization → Firmware loads basic drivers. Boot Manager ( bootmgfw.efi ) → Displays the default Windows logo from a resource table. Kernel Loading → Logo persists until the login screen.

Windows stores its boot logo as a compressed .bmp file inside a firmware table called the BGRT (Boot Graphics Resource Table) . By default, this table is read-only and signed by Microsoft. HackBGRT151 works by: hackbgrt151

Temporarily disabling Secure Boot (or leveraging a signed shim). Extracting the existing BGRT. Replacing the bitmap data with your custom image. Recalculating checksums and re-injecting the table into UEFI NVRAM.

The “151” patch specifically fixes a race condition that caused black screens on systems with Intel Iris Xe graphics and AMD Ryzen 5000-series APUs.

Step-by-Step Guide: How to Install and Use HackBGRT151 Prerequisites

Windows 10 (v1903+) or Windows 11 (up to 22H2, with caution). UEFI firmware (not legacy BIOS). Administrative privileges. A backup of important data (always recommended).

Step 1: Download HackBGRT151 ⚠️ WARNING: Only download from the official GitHub repository ( github.com/Metabolix/HackBGRT ). The “151” version is in the “releases” section as HackBGRT-1.5.1.zip . Avoid third-party mirror sites. Step 2: Disable Secure Boot (Temporarily) Enter HackBGRT151

Restart your PC and enter UEFI settings (usually F2, Del, or Esc during boot). Navigate to Security → Secure Boot → Set to Disabled . Save and exit.

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. Step 3: Prepare Your Custom Image
