[REQUEST] Lenovo B50-45 BIOS Advanced menu unlock

Hi.
Today when I was entered the BIOS it's apper with few other tabs and options (debug, and lot of advanced options in other tabs)
Probably when I pressed the buttons (Fn+F2) to enter bios by mistake I pressed one more button witch allow me to open extedend bios - but really I dont know how I did that and after many tries to do this again I give up...

Mayby someone here with more knowlege in this matter will be able to ulock this options and make it appear all the time?
Or someone just know that trick how to open bios with advance menus?

Here is link for BIOS:
