Our team developing an information display system by using Windows 8.1 as operating system. The computer is configured as auto login and executing our custom program automatically. We have an requirement for showing
black screen until the custom program is run. The BIOS message is disabled by customized firmware and windows logo is disabled by following script:
bcdedit /set {globalsettings} custom:16000067 true
bcdedit /set {globalsettings} custom:16000068 true
bcdedit /set {globalsettings} custom:16000069 true
As a result, most of the information is hidden but the user login screen is shown during auto login process. I would like to know that how to disable all boot message
during the computer booting up just similar behavior as enabling "No GUI boot" option in Windows 7.
