Detailed description:I deleted the Boot Option in Setup Utility when I tried to change to boot from CD/DVD. How can I change it back so I can add the Driver Option Priorities and Boot Option Priorities back.
The Laptop could not boot up after I dropped it!

I got the UEFI boot entries up under Boot Option Priorities but there was no Add New Boot Option to add CD/DVD drive! How can I add the entry to boot from disk?
