Hello, I tried to add a DVD to boot sequence but I couldn't find an option for this. I tried Dell's recommendation but they indicate that hardware might not be recognized by the system. I did use the DVD to install Win 10 initially, but now it doesn't show up. Can someone explain how to add a DVD to boot sequence for a Dell Inspiron 15 using Win 10 with UEFI or Legacy if that is an option? Thanks
