Can not boot the SparkyLinux MATE x86_64 live DVD

[reshadnab]

Hi
Yesterday I downloaded SparkyLinux 3.4.1 MATE x86_64 disk image and burned it to a dvd, but despite my effort I can't get it to boot. I did the md5 hash check and it was ok.Funny is when I use dd and write it to a USB flash disk it boots alright.
I use a Laptop(Fujitsu Lifebook AH532) that has very bad EFI implementation so if I install any linux distro in EFI mode, it breaks the Setup and boot menu(it messes some NVRAM stuff, I don't really know) and I have to go to lot of trouble to fix that. Unfortunately the USB disk boots into EFI mode automatically, but if I use the optical disk boot it gives me an option to choose   which Boot mode I want to use(BIOS/UEFI). so the only way for me is to get the disk I burned to work.
During the boot process there is only an error about failing to start live-config service and some acpi warnings, which is identical to USB boot.
Any suggestions?

If USB is working fine why do you need DVD?

As I explained in my post if I use that for installations it breaks my laptop's setup menu(bios menu).It is described in this post(Notes section):  http://www.linlap.com/fujitsu_lifebook_ah532?s[]=ah532
