techfun89 writes "Microsoft claims that Windows 8 can boot in as few as seven seconds. Microsoft says this isn't necessarily a good thing, especially if you need to interrupt the boot. Apparently things boot so quickly there isn't even enough time to detect keystrokes such as F2 or F8 according to Microsoft's Chris Clark. Clark states that Microsoft will not cut the fast boot time to preserve keystrokes but has come up with some other ways to provide the same functionality.
Windows 8 now has a boot options menu that contains all of the troubleshooting tools, developer-focused options for Windows startup, methods for accessing the firmware's BIOS setup and a method for booting to other devices. This boot options menu lives in a realm that is called WinRE (Windows Recovery Environment).
There are also command line options for accessing the boot menu through shutdown.exe and an "Advanced Startup" option in general settings."
