HackBGRT 1.5.1 is a version of the popular open-source UEFI boot logo changer designed for Windows systems. It allows users to replace the standard Windows boot logo or the manufacturer's vendor logo with a custom image by modifying the Boot Graphics Resource Table (BGRT) during the startup process. What is HackBGRT?

HackBGRT is a free utility that targets UEFI-based computers. On these systems, the boot logo is typically stored within the UEFI firmware, making it difficult to change permanently. HackBGRT works as a custom UEFI application that overwrites the BGRT image in memory each time the computer boots, displaying your chosen graphic instead. Key Features of Version 1.5.1

While newer versions like 2.0.0 and 2.5.1 have introduced more advanced features such as automatic image conversion (supporting PNG, JPG, and GIF) and updated shim support for newer Windows updates, version 1.5.1 remains a widely cited "legacy" version known for its simplicity.

Custom Image Support: Enables the use of any 24-bit BMP image as a boot logo.

UEFI Compatibility: Designed specifically for 32-bit and 64-bit x86 UEFI systems.

Simple Setup: Uses a command-line interface where users can install, disable, or remove the tool by pressing specific keys (e.g., 'I' for install). hackbgrt151

Automated Mounting: The tool automatically mounts the hidden EFI system partition to allow users to place their custom splash.bmp file. How to Use HackBGRT 1.5.1 To use this version, users generally follow these steps: How To Change The Windows 11/10 Boot Logo

The code had been humming for years, a silent sentinel in the UEFI firmware of Elias’s custom-built machine. But today, the default manufacturer’s logo felt like a cage—a cold, corporate reminder of a system he didn't truly own.

Elias reached for a tool called HackBGRT. It was a ghost in the machine, a UEFI application designed for one specific purpose: to overwrite the Boot Graphics Resource Table (BGRT) before Windows could even wake up. "Time for a change," he whispered.

The process was a delicate dance with the system's core. First, he dived into the BIOS to disable Secure Boot—the digital lock that usually prevents unauthorized code from touching the boot sequence. With the gates open, he launched the installer.

A command prompt flickered to life. He pressed "I" to install, and like magic, MS Paint opened. It felt absurdly domestic for a system hack, yet there it was: the canvas for his new reality. He didn't want a logo; he wanted a portal. He pasted a custom 256-pixel wide image—a swirling nebula of neon violets and deep space blacks. HackBGRT 1

He saved the file, closed the editor, and felt the weight of the moment. The script finished its work, swapping the standard Windows boot loader with its own clever imitation. Elias hit "Restart."

The screen went black. For a heartbeat, he feared the "boot loop of death" often whispered about in GitHub issues. But then, instead of the static, white manufacturer's mark, his nebula bloomed across the monitor. It was a small victory, a tiny piece of the digital world reclaimed from the giants.

Underneath the glowing dust of his custom star-field, the Windows loading circle began to spin. The system was still the same, but the entrance was now entirely his own.

7. Verdict: Who Should Use It?

Step 2: Disable Secure Boot (Temporarily)

  1. Restart your PC and enter UEFI settings (usually F2, Del, or Esc during boot).
  2. Navigate to Security → Secure Boot → Set to Disabled.
  3. 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.

5. Comparison with Alternatives

| Method | Persistence | Complexity | Risk | Customization Level | |-----------------------|-------------------|------------|-----------|------------------------------| | hackbgrt | Until firmware update | Medium | Medium | Full logo replacement | | Plymouth | After kernel loads | Low | None | Post-GRUB only | | UEFI firmware tool| Permanent (reflash) | High | High (brick) | Full but dangerous | | GRUB background | GRUB menu only | Very Low | None | Only GRUB stage | Restart your PC and enter UEFI settings (usually

Winner for simplicity + effect: Plymouth. But hackbgrt wins for pre-GRUB customization.

Step 3: Disable Secure Boot Temporarily (Most Cases)

Note: HackBGRT151 can work with Secure Boot enabled if you install its certificate, but for first-time users, disabling it is simpler.

  1. Restart your PC and enter UEFI settings (usually by pressing F2, Del, or F10 during boot).
  2. Navigate to the Security or Boot tab.
  3. Find Secure Boot and set it to Disabled.
  4. Save and exit.

Step 2: Prepare Your Custom Image

HackBGRT151 requires a 24-bit BMP (bitmap) file at a specific resolution. The safest dimensions are:

Why? While your screen may be 1920x1080, the UEFI boot console runs in a lower-resolution mode. An 800x600 image will be centered and scaled cleanly. Higher resolutions often get corrupted or cropped.

Use an image editor (Photoshop, GIMP, or even MS Paint) to:

  1. Create your design on a transparent or black background.
  2. Resize to 800x600.
  3. Save as splash.bmp (24-bit, no compression).

Final Score

Bottom line: hackbgrt is a powerful but niche tool. When it works, it’s magical. When it fails, you’ll be dropped to a GRUB rescue shell. Backup your EFI partition first.

Step 3: Prepare Your Custom Image

Pro tip: Use GIMP or Paint.NET to convert PNG to 24-bit BMP. Use VerticalOffset in the configuration to adjust positioning.
