Hello, I have removed the "accepted solution" banner for you when you click it by accident you can remove it by clicking the three dots and selecting "not the solution".When the stick is working on another device obviously i am wrong and it is properly formatted however i did find something that might help you read this step 2 mentions you need to temporarly disable secure boot .
So after many of various issues i decided to do a clean install. I made a Dell OS Recovery Tool(usb bootable image). booted it to make sure it worked removed it. then wipe the internal drive through bios. it wiped fine whatever.... shut down, attached the usb, boot, f12, no option to select the usb to boot from. what gives? i dblchk the bios  to make sure the bootable usb are enabled, uefi enabled, secured boot enabled, and have toggled all. HELP!!  
After wiping data from storage drive can't boot from usb (Inspiron 7373)
