Microsoft have Modified their Standard boot menu feature with Windows 8, in order to apply new Modern UI recovery environment. Microsoft also reduced the amount of time normally Windows waits for an Interrupt in a booting Sequence to nearly Nothing. To enable Classic F8 shortcut back to work, we have to restore Legacy Boot menu policy, now, to do that
Press WINDOWS key + X , launch Command Prompt.
Now when Command Prompt is Launched, Run
bcdedit /set {default} bootmenupolicy legacy
That 's It, Now you have enabled your F8 key shortcut for boot menu Classic style so when your PC boots up you can use your classic style F8 to view 'classic Advanced Boot options'.
And, in case if you want to revert back your Normal Boot Menu again , you can use command mentioned:
bcdedit /set {default} bootmenupolicy standard
