When I was configuring my Lenovo C440, sometimes the select boot device menu won’t be available after shutdown Windows 8. It becomes available again after I choose reboot instead of shutdown.
After some googling, I realize the shutdown feature has changed in Windows 8. You may switch between complete shutdown or hybrid shutdown.
Explain of Shutdown in Windows 8
MSDN: Delivering fast boot times in Windows 8 and MSDN: Windows On/Off Transition Performance Analysis provides a very detail explain about the new shutdown in Windows 8 from a technical view.
In Windows 95 to Windows 7’s word, with hybrid shutdown, you log-off and go hibernate. When you turn-on your computer next time, it restore from file instead of the traditional boot-up process and save your time.
Problems and Solutions with Hybrid Shutdown
Hibernation takes too much time to save my RAM contents into a file on my ThinkPad R61i with 4GB RAM and Vista. Therefore, I choose to shutdown instead of hibernation to save time and reduce SSD write cycle.
Windows 8 provides hybrid shutdown to balance boot time and shutdown time by skipping the user session. Less to save and quicker to restore. You only need to login again which is good for security concern, too..
The only problems to me is I cannot see my boot device menu. It is not good when I need to use GParted or Clonzilla which need to be select from different bootable device like flash drive or CD-ROM / DVD-ROM.
If you want to disable hybrid shutdown, you may lanuch [Power Options] from [Control Panel]. On the left side bar, choose [Choose What the power buttons do]. Click [Change settings that are currently unavailable] and remove the tick on [Turn on fast startup (recommended)] then [Save changes].
If you have problems to shutdown your computer, try to disable hybrid shutdown.
