how to make copies of selfbootable and nonbootable copies...

[amol00]

I know this question has been asked for a lot of times, but i just got a writer yesterday and i want to know how to make copies of the dc backups i have got. Some of them are self bootable and some of them are non bootable. SO please tell me how to make the direct copies of the games. BTW i use nero burning rom and clone cd. So which command shall make direct copies of the cds.
THank you very much.,
