When I run Kali live it works but when I try to install as OS on harddrive it says missing firmare files and asks do i want to add them from a removal device. The pc is an Acer Aspire E15 currently running ubuntu. I downloaded kali 19.4 iso and burned on usb using rufus. I need help getting these firmware files to complete installation I think. When I continue install and choose to add firmware files later it goes all the way to configure network and just stays there. Nothing happens. Any tips?
