HackBGRT is a popular open-source utility designed to change the Windows boot logo on UEFI-based systems. Version 1.5.1 is a stable release of this tool that allows users to swap out the standard Windows flag or manufacturer logo (like HP or Dell) for a custom image during the startup process. Key Features of HackBGRT 1.5.1

UEFI Support: Specifically designed for modern UEFI systems using the Boot Graphics Resource Table (BGRT).

Image Customization: Users can specify high-quality images, including exact X/Y coordinates for positioning on the screen.

Randomization: It supports cycling through multiple boot images randomly if configured in the config.txt file.

Safe-ish Modification: It doesn't replace the actual Windows bootloader; instead, it installs itself alongside it to overwrite the logo in memory during boot. Step-by-Step: How to Use It

HackBGRT is a popular, open-source tool used to replace the default Windows boot logo with a custom image on systems using UEFI firmware.  Review & Key Features 

High Customization: It allows you to swap the standard Windows or manufacturer logo for any 24-bit BMP image.

System Requirements: It strictly requires a system running in UEFI mode with Secure Boot disabled to function.

Ease of Use: While powerful, it is considered an expert tool. Installation involves running a command-line setup that mounts your system's EFI partition.

Reversibility: The tool includes a simple removal option (typically by running the setup again and selecting 'R') to restore the original logo.  Critical Considerations 

Risk Level: Because it modifies the system's EFI partition, incorrect use can potentially make your computer unbootable. Always ensure you have a recovery plan or backup.

Technical Support: There is no official technical support for installation or usage; users are expected to rely on community documentation and bug reports. hackbgrt151 high quality

Image Limitations: Custom images must be saved as 24-bit bitmap (BMP) files named splash.bmp. Larger resolutions or incorrect formats may cause the tool to fail or display the default logo instead.

HackBGRT 1.5.1: Achieving High-Quality Custom Boot Logos on Windows

Customising your PC is more than just changing wallpapers; for enthusiasts, it starts the moment you press the power button. HackBGRT 1.5.1 is a specific, widely-cited version of the open-source HackBGRT tool designed to replace the default Windows or OEM (vendor) boot logo with a high-quality custom image.

While newer versions like 2.5.1 exist, many users still seek out version 1.5.1 due to its perceived stability or specific compatibility with older UEFI systems. What is HackBGRT 1.5.1?

HackBGRT is a UEFI-based boot logo changer. Unlike old methods that tried to patch system files, HackBGRT functions as a custom UEFI application. It overwrites the Boot Graphics Resource Table (BGRT) in your system's memory during the boot process, allowing your custom image to appear instead of the standard Windows flag or manufacturer logo (like Dell, HP, or Lenovo). Requirements for High-Quality Results

To ensure your custom logo looks professional and "high quality," you must adhere to specific technical requirements during the creation process:

The "High Quality" Caveat

Here is where most blog posts stop. Let’s talk about quality.

Enabling hackbgrt solves the disappearance problem, but it does not magically upscale your logo. If you want a truly high-quality boot experience, you must do two more things:

1. Set the correct resolution in GRUB: If GRUB boots at 1024x768 but your monitor is 4K, hackbgrt will clear the logo, but your splash will look pixelated. Fix: Add GRUB_GFXMODE=1920x1080,auto and GRUB_GFXPAYLOAD_LINUX=keep to your /etc/default/grub.

2. Use a HiDPI Plymouth theme: The default Ubuntu or Fedora text-based themes look cheap. Use plymouth-theme-solar or create a custom theme with a vector logo scaled to your framebuffer resolution.

Image Quality & Performance

• Supported format: 24‑bit uncompressed BMP. Max resolution = your native boot resolution (typically 1920x1080 or 2560x1440).
• Quality: No compression artifacts. The tool automatically centers or stretches (configurable).
• Performance: Zero boot time impact (injection takes < 10 ms). No memory leaks or driver conflicts.

Ease of Setup: ★★★★☆

1. Download HackBGRT-1.5.1.zip from GitHub (Metabolix).
2. Run setup.exe as Administrator – it auto‑detects your EFI System Partition (ESP).
3. Select an image – the tool converts any common format (PNG, JPG) to a compliant BMP.
4. Reboot – the new logo appears immediately.

Note for Secure Boot: You must enroll a custom key or temporarily disable Secure Boot. The tool provides a helper (enroll_key.exe) but this is the most complex step for average users.

2. Color Depth (24-bit vs 16-bit)

OEM boot screens often use a limited color palette (RGB 565, or 16-bit). This causes color banding—visible gradients and blotches in what should be a smooth image. High-quality HackBGRT mods leverage 24-bit true color (RGB 888), eliminating banding for photographic or gradient-heavy logos.
