Lenovo Ideapad 500 15ACZ Boot issue

I wanted to install a fresh copy of windows 10(via usb) in my Lenovo Ideapad 500 15ACZ, but cant seem to get the laptop to boot from the usb device. All the devices are 100% functional, and after thorough research (google -_- ) I found out that Lenovo Ideapads require one to press Fn+F11 or Fn+F12 at loadscreen. Tried both but still doesnt boot from the USB. Note: Lenovo forums mention about a certain 'Novo button' that works as a shortcut button for access to BIOS but mine doesnt have this button. Please help

its hard to say how to access boot rather trying it f2f but did you try f2 and f8 ? or fn+ ?if not then try that
