Spectre x360 Convertible
Microsoft Windows 10 (64-bit)

I recently purchased the HP DVD 600s external drive to attach to the HP Spectre x360 Convertible laptop but am unable to get the laptop to boot from a CD or DVD.  I've disabled secure boot in the bios and moved the CD option to the top of the list in the UEFI boot order but booting up bypasses the CD/DVD drive, goes straight to the hard drive, and starts Windows instead.  The DVD disc boots fine on another computer.  My laptop product number is T629UA#ABA.  Please help.  Thank you.
