In general, it does _not_ work to copy a bootable CD using "dd". If you read README.copy you know that you should use "readcd" instead.

I'm not an expert but as I understand it: Could you please explain why you want to use mkisofs at all? What I understood from your 1st mail is that you want to make a simple copy of it. I.e.: simply write the data from the original CD to a blank CD-R. If you want to make changes to the file system, e.g. add/replace/change/delete files you need of course to make a new iso-image via mkisofs. For all these cases there are README files in the cdrtools package.

Well the mkisofs didn't work! I'm not an expert but as I understand it: When you mount a cdrom you can't/don't see the boot information. Therefore when making an iso, you don't get the boot information.

I can't understand what's your problem. Why do you use mkisofs at all? The data on the original cdrom is an ISO9660 image, isn't it? So if you can boot the original CD you will be able to boot a copy of it. Kind regards Carsten -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Why do you use mkisofs if you're just copying a cdrom? I usually use 'dd if=/dev/cdrom of=/tmp/filename.iso' to create an ISO image from the original cdrom and then 'cdrecord /tmp/filename.iso' to burn a new cdrom from that image. This method works well for data only and has no problems with bootable cdroms. D. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Copying a bootable cdrom
Copying a bootable cdrom. I have a cdrom that I am trying to copy. It is a bootable cdrom. I can make a copy of it, but I can't boot off of it. I am assuming that I need to do something different in the mkisofs command. I even tried to to point the iso creation process at /dev/hda, but that did not work either. -- Mike Cannon Infrastructure Systems Administrator Vice President for Information Technology Purdue University 1061 Freehafer Hall (FREH) West Lafayette, IN 47907-1061 office phone: 765.494.6357 office fax: 765.496.1380 email: [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
