HackBGRT151: The Ultimate Guide to Changing Your Windows Boot Logo

Core Idea

• UEFI firmware draws a logo (e.g., Dell, Lenovo, ASUS) before handing over to the OS.
• Linux’s efi-pstore, efivarfs, and the BGRT driver (CONFIG_ACPI_BGRT) expose this logo.
• hackbgrt intercepts or replaces the BGRT entry point to point to a custom bitmap (BMP) in memory.

Step 4: Run HackBGRT151

1. Extract the ZIP to a folder (e.g., C:\HackBGRT).
2. Right-click setup.exe → Run as Administrator.
3. The tool will:
   • Detect your current BGRT.
   • Show the existing boot logo (default Windows).
   • Ask for your custom BMP file.
4. When prompted, select your prepared BMP.
5. Confirm the offset and position (usually default settings work).
6. Type Y to write the new BGRT to firmware.
