An ISO file contains not only files and folders but also the disk file system metadata. This includes boot code, structures, and attributes. This is why burning an ISO image is different from writing files from a CD or DVD.

To burn an ISO image, you need a CD or DVD burning program that can allow you to write on the disk.

How to Burn an ISO under Linux

Linux OS has Cdrtools, a set of command line applications that enables users to burn CD/DVD/BluRay media. To burn a CD using Cdrtools, first scan all your SCSI devices using this command:

cdrecord -scanbus

After determining the name of your device, use this command to write the ISO files you want to burn into the CD: "cdrecord -v -pad speed=1 dev=0,0,0 filename.iso". 0,0,0 is your device name while filename.iso is the image you want to write on the CD/DVD. You can also change the burning speed according to your preferences.

You can also use Graphical User Interface (GUI) Front-Ends to burn disk images into a CD/DVD. GUI Front-Ends are ideal burning tools for inexperienced users. Listed below are some Linux-compatible GUI Front-Ends that are available for download:

* X-CD Roast has a Drag&Drop feature that makes file burning easy. It copies and creates data, audio, mixed-mode, and multisession. It has a bootable CD support and experimental DVD-Video support.
* gcombust allows you to burn data without making an image (CD-to-CD data copy on the fly). It tells you which directories/files to use to maximize disk space. gcombust is not recommended for Audio CD creation.
* GNOME Toaster also features drag-and-drop burning method and can burn and encode mp3 files to a disc on-the-fly.
* Disc-O-Matic can be used for burning and archiving multiple CDs.
* KisoCD has features like burn on-the-fly, disk image creation, and multisession and bootable CDs creation.
* BurnIT is programmed in Java and combines cdrecord, mksiofs, and cdda2wav-0.95 to make it a CD burning package for Unix platforms.
