winlogon error on Windows 8 Release Preview

I have updated Windows 8 from Consumer Preview to Release Preview. When I shutdown the Windows I get a message as "winlogon.exe - No Disk"!

Solution is to turn off fast startup.

- Search "Shutdown Settings" from Settings, and click to run "Change what the power buttons do".



- "Change settings that are not currently available".



- Scroll-down and uncheck "Turn on fast startup (recommended)" and Save changes.
