Jan 29, 2020 2. 8oot Logo Changer Tool. It is a free tool designed to change the default boot logo picture of the Windows boot screen with a custom picture. The tool does the job by replacing the default images in the bootloader. For this, one needs to turn Test Signing mode on. Changing the boot screen logo when Test Signing mode is turned off will show a.
HackBGRT is intended as a boot logo changer for UEFI-based Windows systems.
When booting on a UEFI-based computer, Windows may show a vendor-defined logo which is stored on the UEFI firmware in a section called Boot Graphics Resource Table (BGRT). It's usually very difficult to change the image permanently, but a custom UEFI application may be used to overwrite it during the boot. HackBGRT does exactly that.
Important: If you mess up the installation, your system may become unbootable! Create a rescue disk before use. This software comes with no warranty. Use at your own risk.
setup.exe
and follow the instructions.If you only need HackBGRT for Windows:
[EFI System Partition]EFIHackBGRT
.boot=EFIMicrosoftBootbootmgfw.efi
in config.txt
.EFIHackBGRTbootx64.efi
.If you need it for other systems as well:
[EFI System Partition]EFIHackBGRT
.boot=EFIyour-actual-boot-loader.efi
in config.txt
.EFIHackBGRTbootx64.efi
as your default boot loader with efibootmgr
or some other EFI boot manager tool.On 32-bit machines, use bootia32.efi
instead of bootx64.efi
.
The configuration options are described in config.txt
, which should be stored in [EFI System Partition]EFIHackBGRTconfig.txt
.
The image path can be changed in the configuration file. The default path is [EFI System Partition]EFIHackBGRTsplash.bmp
.
The image must be a 24-bit BMP file with a 54-byte header. That's a TrueColor BMP3 in Imagemagick, or 24-bit BMP/DIB in Microsoft Paint.
Multiple images may be specified, in which case one is picked at random.
If something breaks and you can't boot to Windows, you have the following options:
[EFI System Partition]EFIHackBGRTbootmgfw-original.efi
into [EFI System Partition]EFIMicrosoftBootbootmgfw.efi
by some other means such as Linux or Windows command prompt.You can suppress Windows elements that appear when Windows starts or resumes and can suppress the crash screen when Windows encounters an error that it cannot recover from. This feature is known as Unbranded Boot.
Important
The first user to sign in to the device must be an administrator. This ensures that the RunOnce registry settings correctly apply the settings. Also, when using auto sign-in, you must not configure auto sign-in on your device at design time. Instead, auto sign-in should be configured manually after first signing in as an administrator.
Windows 10 Enterprise, Windows 10 Professional, or Windows 10 Education.
Turn on, Enable: To make the setting available to the device and optionally apply the settings to the device. Generally 'turn on' is used in the user interface or control panel, whereas 'enable' is used for command line.
Configure: To customize the setting or sub-settings.
Embedded Boot Experience: this feature is called 'Embedded Boot Experience' in Windows 10, build 1511.
Custom Boot Experience: this feature is called 'Custom Boot Experience' in Windows 10, build 1607 and later.
Unbranded Boot is an optional component and is not enabled by default in Windows 10. It must be enabled prior to configuring. For end-users, Unbranded Boot is available through Control Panel > Programs > Programs and Features > Turn Windows features on or off.
If Windows has already been installed you cannot apply a provisioning package to configure Unbranded Boot; instead you must use BDCEdit to configure Unbranded boot if Windows is installed.
Shut down button disappeared. BCDEdit is the primary tool for editing the startup configuration and is on your development computer in the %WINDIR%System32 folder. You have administrator rights for it. BCDEdit is included in a typical Windows Preinstallation Environment (Windows PE) 4.0. You can download it from the BCDEdit Commands for Boot Environment in the Microsoft Download Center if needed.
Open a command prompt as an administrator.
To disable the F8 key during startup to prevent access to the Advanced startup options menu, type the following:
To disable the F10 key during startup to prevent access to the Advanced startup options menu, type the following:
To suppress all Windows UI elements (logo, status indicator, and status message) during startup, type the following:
You can also configure the Unattend settings in the Microsoft-Windows-Embedded-BootExp component to add Unbranded Boot features to your image during the design or imaging phase. You can manually create an Unattend answer file or use Windows System Image Manager (Windows SIM) to add the appropriate settings to your answer file. For more information about the Unbranded Boot settings and XML examples, see the settings in Microsoft-Windows-Embedded-BootExp.
The following table shows Unbranded Boot settings and their values.
Setting | Description |
---|---|
DisableBootMenu | Contains an integer that disables the F8 and F10 keys during startup to prevent access to the Advanced startup options menu. Set to 1 to disable the menu; otherwise; set to 0 (zero). The default value is 0. |
DisplayDisabled | Contains an integer that configures the device to display a blank screen when Windows encounters an error that it cannot recover from. Set to 1 to display a blank screen on error; otherwise; set to 0 (zero). The default value is 0. |
HideAllBootUI | Contains an integer that suppresses all Windows UI elements (logo, status indicator, and status message) during startup. Set to 1 to suppress all Windows UI elements during startup; otherwise; set to 0 (zero). The default value is 0. |
HideBootLogo | Contains an integer that suppresses the default Windows logo that displays during the OS loading phase. Set to 1 to suppress the default Windows logo; otherwise; set to 0 (zero). The default value is 0. |
HideBootStatusIndicator | Contains an integer that suppresses the status indicator that displays during the OS loading phase. Set to 1 to suppress the status indicator; otherwise; set to 0 (zero). The default value is 0. |
HideBootStatusMessage | Contains an integer that suppresses the startup status text that displays during the OS loading phase. Set to 1 to suppress the startup status text; otherwise; set to 0 (zero). The default value is 0. |
If Windows has not been installed and you are using Windows Configuration Designer to create installation media with settings for Unbranded Boot included in the image, or you are applying a provisioning package during setup, you must enable Unbranded Boot on the installation media with DISM in order for a provisioning package to successfully apply. First you have to create the image or package.
Create a provisioning package or create a new Windows image in Windows Configuration Designer by following the instructions in Create a provisioning package.
In the Available customizations page, select Runtime settings > SMISettings and then set the value for the boot screen settings. The following values are just examples.
Tip
See SMISettings in the Windows Configuration Designer reference for more information about the available SMISettings.
Once you have finished configuring the settings and building the package or image, you use DISM to apply the settings.
Open a command prompt with administrator privileges.
Copy install.wim to a temporary folder on hard drive (in the following steps, it assumes it's called c:wim).
Create a new directory.
Mount the image.
Enable the feature.
Commit the change.
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.
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.
