If it's not working in windows you can always run it via USB.  1. Download the exe, and save it to a blank USB drive.  2. restart (with USB still connected) and hit F12 on boot.  3.  Scroll down until you see bios flash update and select the exe file from the USB    
Hi thanks in advance, I saw an update at SupportAssist so I clicked the button but all that says is error.So downloaded BIOS file manually on dell site, but that file won't open. Any solutions are appreciated.
