Can`t install the latest version of BIOS on Legion Y520-15IKBN

So I got this Legion Y520-15IKBN, had some problems when I bought it, sent it to warranty, reinstalled windows a couple times, etc.

 I haven`t been updating my windows for like a long time untill a week ago I strated doing some updates and yesterday I saw that I had one more update that I can do.So like I do from time to time I go to pcsupport.lenovo to check if all my drivers are good and I saw that I got one driver that I need to upgrade BIOS 10 but when I try to install it id doesn`t work, I tried to do it manually but when I do that I get an errror saying: "mount the efi system partition fail". Any suggestions?

Does Disk Management indicate that you have an EFI partition?  Was your Windows reinstall in legacy mode by any chance?
