The boot configuration system had to change, allegedly, to support EFI[^]. Since it's a new system, the old tools in Windows 2000 cannot modify the configuration. There is a GUI interface, in the same place as in Windows 2000, XP and Server 2003: Control Panel, System, Advanced tab, click Settings under Startup and Recovery, then select the appropriate choice from the Default Operating System dropdown. bcdedit is really for people who want to modify default boot options, for example loading with the debugger enabled.
Stability. What an interesting concept. -- Chris Maunder
