I just bought anew msi z97 gaming 7 motherboard and i7 4790k . I have been trying to update the bios using the m-flash option in the msi uefi bios . I downloaded the latest bios to my usb flash drive and I extracted the bios in to a folder . I then booted back in to the uefi bios and clicked on m-flash I then clicked on update bios and chose my usb flash drive . I then get a message saying there is no bios file on the usb flash drive . what am I doing wrong ? I downloaded the updated bios to my usb flash drive and extracted it to a folder . can you please help ?
