How it Works

Lenovo UEFI Boot Logo Changer operates by leveraging Lenovo's support for user customization of the boot logo through the ESP (EFI System Partition). The process involves placing a custom image into the ESP partition and then configuring UEFI variables to instruct the DXE (Driver Execution Environment) program to read and display the user-defined logo during the system's boot process.

So this tool do:

1. Read UEFI Variables to determine whether the system supports Logo Change;
2. Place Selected Image in ESP Partition;
3. Modify UEFI Variables to enable the UEFI program to correctly set and display the customized logo.

All of the above operations need to be performed with administrator privileges.
