Hi, i cannot access bios using F2 or even F10 settings function with Samsung notebook. When i push F2 repeatedly it will go to a black screen after the samsung boot logo. Likewise, when i select settings using F10 function - boot loader does load, however. My PC boots into windows fine however will still not even allow me into UEFI bios using the advanced function in windows. Do i need to re-flash the bios? has something corrupted? Model is NP900X3E-A02US Thanks
