So I was trying to follow the guide provided on these forums, however, I hit a snag when trying to download the Bootpack for my laptop. Every thing I have read states to just use the file for the Dell E7440, however, when I follow the guide here and try to download the file for my processor model it says the attachment is unavailable. I found another EFI folder, but can't get the sound working so I was hoping someone here might be able to help me track down the correct Bootpack. Any help would be greatly appreciated.
