I am new to using Darik's Boot and Nuke but have heard a lot of great things about it. When I try to run this CD it gives me the following error:
"[1.735864] sd 2:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA"
and then just hangs. I have burned the .iso to several different cd's, some do not boot to the cd the rest give me this error. Is there a specific type of cd media that is better, I am currently using a dvd-r. Thanks in advance for the help.
