Update the boot splash in Windows 10
Update the boot splash in Windows 10
If your bios there's an option called something like "Display splash screen on boot", turn this off and it'll go back to classic white text on black and the Windows logo on boot. Can I ask why this bothers you? It's designed to show you UEFI boot mode is enabled and working and it changes nothing.
It's referred to as a fullscreen logo in the BIOS. Turning it off will give you what you need.
