Hi Ron, thank you for the heads up on Rufus as I was able to boot to a USB.  I use a different ISO boot program and it didn't work. To sum things up disable secure boot in the BIOS to be able to boot to a USB device or CDROM.  Create your image with RUFUS that will contain your ISO and when you boot in post by hitting F12 constantly you will see your device in the list. Thanks again!        
I just purchased a Dell Inspiron 3880.  I would like to be able to boot from USB or CDROM but I can't and when I looked closer at the Bios I don't see any options for it.  I also placed a circle in the area which I had seen previously on other Dells Uefi options.  Can someone please advise how I can add my USB and CDROM for the Dell Inspiron 3880?  I have contacted support today and was transferred three times and in my opinion is very weak technical support as they have no knowledge what bios is and they want to dismiss me right away, very frustrating...
