RE: Need bios latitude files(NOT APPLICATION TO GAIN FILES, IT WILL GIVE ERROR)
What you likely have is an OEM copy of Windows 8 from some other manufacturer - Acer, Lenovo, etc.
It's looking for the Acer, Lenovo, etc., information - it's not looking for a BIOS update from Dell.
You either need to purchase a set of recovery media from Dell or a full retail copy of Windows 8 with a valid license key.
This situation has absolutely nothing to do with a BIOS update on your current system.
