First, let's address the core technical limitation. Unlike consumer motherboards from ASUS or MSI that accept high-resolution JPEGs, Lenovo’s UEFI BIOS (especially on ThinkCentre, ThinkStation, and older ThinkPad models) adheres to a strict legacy standard: EPA (Energy Star) logo compliance. If you extract from a modern Lenovo laptop,

Historically, the EPA logo displayed during boot was a 1-bit or 4-bit bitmap. Lenovo maintained this standard for custom boot logos. Through reverse engineering and official BIOS documentation, the accepted parameters are:

If you try to upload a JPEG, PNG, or a BMP that is 300x300, the Lenovo BIOS Flash utility (usually WinFlash64.exe or the BIOS Setup utility) will reject it with a vague error: "Invalid Logo Image."

Convert to 24-bit. Go to Image > Mode > RGB Color (8 bits/channel = 24-bit total).

Save as BMP.

Double-check file size. A proper 120x120 24-bit BMP is always 43,254 bytes. If yours is different, revisit your color depth or compression settings.

Windows 11/10 Paint cannot index colors properly, but you can use it for monochrome logos.

Export as Windows BMP (.bmp).
