I need disablepassword.efi file to unlock my bios

I have an acer aspire v3771g. I was trying to remove my bios password coz it became a pain entering it all the time. So i entered bios and entered the old password then pressed enter twice for a blank password. I for some reason pressed f9 then f10 and when it turned on i was prompted for a password. From then on iv tried it all, cmos battery, jumper shorting. Etc. Failed. Cant boot into windows nor bios. The manual says use disablepassword.efi file and put it in an empty flash disk and press ctrl alt and tap enter repeatedly on startup. Problem is i dont know where to get disablepassword.efi file. Someone out there help
