Security and safety recommendations

| ✔️ | ❗ Why It's Important | | :--- | :--- | | System Compatibility | UEFI firmware required. Legacy BIOS systems are not supported. Verify this via the System Information panel ( msinfo32 ). | | Image Format | The image must be a 24-bit uncompressed BMP file with a 54-byte header . Keep it reasonable in size (under 2MB) and consider a 1024x768 resolution for best results. | | Secure Boot | While a shim is provided for Secure Boot, you may need to disable it or manually approve HackBGRT via the shim. Disabling Secure Boot is the simpler option for testing . | | TPM & BitLocker | Using HackBGRT introduces a change to the boot process. This will likely be detected by TPM and trigger BitLocker recovery.

A recovery drive or full system backup is your safety net. |
