In the position pointed by the red arrow, the computer will pop up a message saying that a new removable device is detected. Please select not to format it:
Open this removable device, and check the content. We will see a directory named os_show. The booting logo is named bootlogo.bmp.
The format is bmp with a resolution of 1280×720 and 32 bit format. We just need to replace this file with your own logo.
