Ok so I have a Dell Inspiron 17 7720 laptop that had a bad mother board.I replaced it with another one and all works fine now. I installed Windows 10 Pro and noticed that I get my screen flashing on so I went to the dell Website to make sure I have all the right drivers. It recommended a few updates and also showed A17 BIOS that could be used also. I downloaded the files and then tried to do the flash bios program and got the above error. Found software PC Scan and repaitr that was recommended and it did not resolve any issues, instead found some malware and wants my CC card to repair software errors (not happening). So my issues are flashing screen which I did not have with Lunix Mint and the command line error when trying to upgrade my BIOS. Thanks
