I sometimes encounter this issue too. Try holding down the option immediately after the screen goes blank when you do a restart. If not use the Cmd+R to boot into recovery and choose the startup disk there.

You may also launch the control panel using cmd 


C:\Windows\System32\AppleControlPanel.exe
