Boot UI Tuner: Customize Windows 8 Boot Menu Options

http://winaero.com/

Windows 8 has a new boot loader with a graphic interface and options like troubleshooting problems. It's harder now, though, to quickly get to advanced options or load a different OS (e.g., by pressing F8). Boot UI Tuner solves this problem, allowing you to configure your boot options and tweak the boot loader.
The small, portable utility enables you to very quickly and easily tweak Windows 8's boot screen and options at startup. Just check off the ones you want—e.g., show advanced options like using safe mode or bring back the Windows 7-style boot loader. The changes will take effect when you restart.

You can also disable the Windows logo, loading circle, and messages, potentially speeding up your start time with this free utility.
