lenovo yoga 3

I think my yoga 3 has insydeh20 bios although not 100 per cent sure.  I bought this secondhand and put a bios password on it when i got it.  Old veteran here and its been a few yrs and my windows 7 crashed so wanted to reinstall 7 but alas i can not for the life of me remember the password so I can change boot order.   I am a rookie at this so if it is not insyde bios but pheonix I apologize.  I just would love to know if there is a way around it or do i have to buy a new motherboard or just have a big paperweight.
thanks in advance
