Windows 10: Restore vendor BGRT boot logo, instead of unbranded Windows10 blue logo?

How can I restore vendor BGRT boot logo, instead of unbranded Windows10 blue logo? I had to swap the hardware in my ASUS desktop.For this purpose it was necessary to disable the secure boot. So I made a mistake, and deleted secure keys by the way from BIOS.After fixing the hardware, enabling Secure Boot and reloading default vendor keysBIOS option, secure boot seems enabled, but the BGRT logo is not displayed on boot anymore.How can I bring back that logo? I do not need a custom logo. Just the one that is written in the BIOS, I want it instead of "blue windows", as it was before.

Windows boot up logo

Any machine booting in Legacy MBR mode displays the blue Microsoft window logo at that stage of booting.

A machine with a UEFI bios can have an OEM logo that replaces the blue window with the OEM logo, but this only happens when booting a UEFI/GPT install of Windows. This logo is held in the firmware's Boot Graphics Resource Table (BGRT). All bar one of my UEFI Dell machines do that, showing a Dell logo above the spinning dots. The one exception is a Dell E4310, its early UEFI version has some shutdown issues when Windows is installed as UEFI, so it has a Legacy MBR install and shows the blue window at boot.

What is your OEM, in UEFI it should normally be their splash screen appearing above the dots. I suspect your black screen with just the spinning dots means that its BGRT is corrupt, unreadable, or just empty. Have you updated its bios recently, perhaps with a custom bios?

How to change the boot logo in Windows 10

From MS Hardware DEV site:

In the following image, the BootLogo is identified by the green outline, the BootStatusIndicator is identified by the red outline, and the BootStatusMessage is identified by the blue outline.




Replace the startup logo

The only supported way to replace the startup logo with a custom logo is to modify the Boot Graphics Resource Table (BGRT) on a device that uses UEFI as the firmware interface. If your device uses the BGRT to include a custom logo, it is always displayed and you cannot suppress the custom logo.

The Dell logo is a custom BootLogo embedded in the firmware. It is shown twice, first by the POST, the again as a replacement for the generic 'blue window' BootLogo while Windows boots.

Was that a legacy MBR install previously? Probably, as a UEFI boot will use the custom logo from the firmware (if present) in preference to the default MS logo.
