resetting my Bios (insydeh20 rev 3.7) without any OS on it? (FreeDos)

Hey there! I have the Lenovo Y50-70 with the 256 gb ssd and an i7 chip with the GTX 860M and 16Gb ram! I have no idea if you need that to help out actually! So my Problem is that i wanted to install Windows 8 on it and i had several Problems!
Now I want to fix these Problems (FreeDos isn't starting automatically anymore but there is written Cheking media_ and then failed to boot EFI from IPv4 and so on) by resetting the Bios or that new UEFI (insydeh20 rev 3.7)!

My Problem is that I litteraly can't find that button anywhere!! And I have no OS on it to reset it from there as a guy wrote in another thread!! And that woudln't work, too because he always says that Checking Media_ and then that Bios message: failed to boot from IPv4 and so on! Because I tried to install Windows 8 from an external DVD driver and selcted Legacy support and Legacy first and then I put that External storrage on first place to boot! But now my SSD and external storage and so on are not written there anymore! Just that Ipv4 and IPv6!?!! Can you please out there!! It is really exasperating!!!!

So again because I don't really have structure there ^ : I need to reset my Bios (insydeh20 rev 3.7), but I don't have any OS on my Laptop(Just FreeDos but it doesn't work (failed to boot always))

Thank you!!!
