Are you able to boot from other external media on your UEFI laptop? Ie. have you made the necessary adjustments in your UEFI "not a bios BIOS"? You have to disable secure booting and enable CSM, IIRC. Then, when you go to the boot priority menu in 'BIOS' it should list the CD among the bootable partitions. Then you need to either put it in position #1, or go to the boot override menu (a long-winded version of F12) put the cursor on the burner and hit ENTER.

BTW I have this information on the tip of my fingers because I just acquired an ASUS N550JV, and had to figure out how to boot Linux myself, since the technical gurus at Staples, where I bought it assured me that it was absolutely impossible without first wiping everything off the hard drive, including Windows 8 and all the Asus apps.

I've now got about 9 days left in which to decide whether to keep this machine or return it for refund. The critique of UEFI on Wikipedia is pretty discourageing.
