Introduction
In this article we explain advanced startup options in Windows 8. The Advanced Startup Options menu allows you to specify various options for how you would like Windows 8 to start or to provide access to repair and diagnostic tools in the event that Windows is unable to start. In previous versions of Windows you were able to access the advanced startup options menu by clicking on the F8 key when Windows started. In Windows 8, though, they removed this capability to offer a faster boot experience. Due to this you need to access the advanced startup options menu differently.
