Hackbgrt151 May 2026

is a specialized, open-source utility designed for UEFI-based Windows systems that allows users to replace the default startup logo (the Windows flag) with a custom image. Overview & Utility The tool operates by modifying the Boot Graphics Resource Table (BGRT)

, a standard UEFI feature that Windows uses to display a manufacturer or OS logo during boot. It is widely considered the "go-to" recommendation for users who want to personalize their boot experience on modern hardware. Key Features Custom Branding:

Enables the use of any custom BMP or PNG image as the boot logo. Integrated Setup:

The installer automatically launches MS Paint to allow for immediate image editing and alignment during the installation process. Automatic EFI Handling:

It simplifies the process of mounting and modifying the EFI System Partition, which is typically hidden from users. Critical Considerations Secure Boot Conflict: By default, HackBGRT requires Secure Boot to be disabled

because the custom EFI binary it uses is not signed by Microsoft. Advanced users can circumvent this by signing the binary with their own keys, though this is a complex and risky process. Risk Profile:

Modifying the bootloader carries an inherent risk. If the EFI partition is improperly handled or if there are multiple bootable drives, the automatic setup may fail. Compatibility: hackbgrt151

While highly effective for UEFI systems, it does not support legacy BIOS installations. Some users have reported issues with specific hardware, such as HP laptops, where the system resists changes to the boot order. User Experience Pros & Cons

One of the few reliable ways to change the boot logo on Windows 10 and 11. Completely free and open-source via

Includes a straightforward "uninstall" option to restore the original logo. Lacks a "silent install" option for enterprise deployment.

Visual bugs can occur, such as the original logo flashing for a second before the custom one appears, often due to firmware limitations. step-by-step guide

8. Future of BGRT Hacking

With the move to systemd-boot and UKIs (Unified Kernel Images), the BGRT approach becomes less relevant. Newer systems may use the Framebuffer Boot Logo (FB logo) or EFI Boot Splash protocols. However, hackbgrt remains the only low-level method to replace the very first logo displayed on a UEFI system.

Version 151 is stable, but no active development exists since 2022. Use the -git version for newer kernels (6.x+).

How HackBGRT151 Works: The Technical Underpinnings

To understand HackBGRT151, you need to know a bit about the UEFI Boot Manager. Modern Windows uses a file called bootmgfw.efi to start the OS. This executable contains a bitmap resource—the boot logo. The original HackBGRT worked by patching this EFI executable.

HackBGRT151 improves upon this by:

Crucially, HackBGRT151 does not modify your Windows kernel or system files beyond the boot environment. This makes it safer than many other customization tools.

6. Real-World Testing & Results

Tested on:

Performance impact: Zero. The patch just remaps a memory pointer.

Troubleshooting Common HackBGRT151 Issues

Despite its simplicity, users often encounter problems. Here’s how to fix them:

| Issue | Possible Cause | Solution | |-------|----------------|----------| | Black screen on boot | Corrupted BMP or wrong resolution | Boot from Windows USB → Command Prompt → Navigate to C:\HackBGRT → Run restore.bat | | Logo is tiny and centered | Using a low-res image on a high-res screen | Create an 800x600 BMP with a black border; the EFI will center it. | | Secure Boot violation error | Secure Boot re-enabled without enrolling the certificate | Reboot → Disable Secure Boot → Re-run HackBGRT151 and choose "Install Certificate" | | "Failed to find bootmgfw.efi" | Windows installed on a different drive or using MBR (Legacy BIOS) | Convert your disk to GPT and switch to UEFI mode. HackBGRT151 requires UEFI. | | Logo shows for a second, then disappears | Fast Boot is hiding the logo | In Windows Power Options, disable Fast Startup. |

7. Verdict: Who Should Use It?

The Future: HackBGRT and Windows 11 24H2+

As of 2025, Microsoft has hardened BGRT protections in Windows 11 24H2 (Build 26000+). HackBGRT151 does not work on these builds due to new Hypervisor-Protected Code Integrity (HVCI) checks. The developer is working on “HackBGRTnext,” but for now, stay on 23H2 or older for boot screen customization.
