In the Consumer Preview, the shutdown command has a new option: /o
In combination with the restart switch /r it apparently restarts the computer with advanced boot options menu, so it can save setting this up in Msconfig if you find it difficult to get to at boot-time with F8/Shift-F8.
It would also be possible to create a Desktop or Metro shortcut for
shutdown /r /o /p shutdown /r /o /t 00 if you are trying to sort out an awkward problem, and need to repeatedly alternate from normal to safe mode boots.
Here is the full shutdown help:
Another update for the Consumer Preview Control Panel>Power Options>System Settings, Shutdown Settings...
Usage: shutdown [/i | /l | /s | /r | /g | /a | /p | /h | /e | /o] [/hybrid] [/f]
[/m \\computer][/t xxx][/d [p|u:]xx:yy [/c "comment"]]
No args Display help. This is the same as typing /?.
/? Display help. This is the same as not typing any options.
/i Display the graphical user interface (GUI).
This must be the first option.
/l Log off. This cannot be used with /m or /d options.
/s Shutdown the computer.
/r Full shutdown and restart the computer.
/g Full shutdown and restart the computer. After the system is
rebooted, restart any registered applications.
/a Abort a system shutdown.
This can only be used during the time-out period.
/p Turn off the local computer with no time-out or warning.
Can be used with /d and /f options.
/h Hibernate the local computer.
Can be used with the /f option.
/hybrid Performs a hybrid shutdown of the computer.
Must be used with /s option.
/e Document the reason for an unexpected shutdown of a computer.
/o Go to the advanced boot options menu and restart the computer.
Must be used with /r option.
/m \\computer Specify the target computer.
/t xxx Set the time-out period before shutdown to xxx seconds.
The valid range is 0-315360000 (10 years), with a default of 30.
If the timeout period is greater than 0, the /f parameter is
/c "comment" Comment on the reason for the restart or shutdown.
Maximum of 512 characters allowed.
/f Force running applications to close without forewarning users.
The /f parameter is implied when a value greater than 0 is
specified for the /t parameter.
/d [p|u:]xx:yy Provide the reason for the restart or shutdown.
p indicates that the restart or shutdown is planned.
u indicates that the reason is user defined.
If neither p nor u is specified the restart or shutdown is
xx is the major reason number (positive integer less than 256).
yy is the minor reason number (positive integer less than 65536).

Turn on fast startup (recommended) replaces Turn on hybrid boot (recommended) and some explanatory text has changed:
I would guess that like on a Tablet, the power button is expected to be used to shut down in the way that the user configures, but in most cases, the
hybrid boot fast startup would be the option for everyday use - and thus a single keypress. Other shutdown options can be configured for the power button if wished. Restarts are programmatically invoked following installations and updates, but are available from the power menu on the charms menu etc if needed for maintenance etc.
In time, even the desktop may be largely gesture controlled, and I find the simplification of screen real estate is welcome. I can live with invisible buttons, as long as I know they are there, and searching directly by typing on a particular screen is great.
To shut down by powering down the machine is a great no-no for Windows users - we must "always shut down Windows properly"since time immemorial - it is as great a paradigm shift as having to go to the start button to shut down in Windows 95, or to press Ctrl Alt Del to log on in Windows NT, which caused great consternation to users in their time, but as always, we get used to it.
