The simplest, most direct way would be to use an external USB DVD drive. You will need to access the Boot Options in the BIOS to set the computer's boot order to USB as the first choice. Once you do that you can boot from the recovery disk and proceed with the restore.
Have you tried to do a restore from the hdd using what Samsung refers to as "Recovery Solution 4"? From the Samsung website here: http://www.samsung.com/us/support/Su...224&fm_seq=392
(scroll down to the sections describing how to do a restore) It seems that you should press F4 when you first see the Samsung logo to access "Recovery Solution 4".
