This really should have been covered on the main download page for the BIOS update. I'm trying to update my BIOS on a Yoga 2 Pro but alas Lenovo has made BIOS updates OS dependant. Here I am used to just going to the BIOS putting the .img file on a usb stick and select flash. That would be too easy and I'm sure confused alot of Windows users. The problem I am having first of all is I cannot find a changelog file. Why would I want to flash something that I have no idea what it does? I need to know what I'm flashing first. The second problem is I cannot even extract the downloaded .exe file, its not a .cab, .zip or .rar. If I could extract it, all I should need to do is make a bootable usb with the .img file right? Anyone in Lenovo support whatching this thread?

Answering my own question here but here is a solution. Download this Windows 8.1 live usb/cd:
I'm using a Yoga 2 Pro and it was kind of picky how the usb was "burned" was unable to use dd and or suse studio image writer had to use rufus on a windows box choosing gpt for uefi with 4096 block size. Then I just ran the exe. Something Lenovo tech support should know about.
