I have totally no experience with Windows, must check it out
I found this tho on dual boot:
There have been many Windows 8 users complaining about various restart and shutdown issues when Fast Startup (aka: hybrid boot or hybrid Shutdown) is turned on. They report that their computers restart themselves as soon as the sign in screen appears, and some that their computer systems hang while rebooting or shutting down the system.
If you experience any of the issues, then you might turn off "Fast Startup" to see if it was the cause.
If you dual boot Windows 8 with a previous version of Windows (ex: Windows 7, Vista, XP), then it is recommended to turn off Fast Startup to avoid the issues above.
