Write to Physical CD/DVD with Xorriso

Introduction

I recently discovered that burning hybrid ISOs onto a physical CD/DVD on Rocky Linux using graphical tools poses a challenge. Thankfully, Xorriso is a simple to use CLI app that handles this task well!

Problem Description

Burn an ISO onto a physical CD/DVD.

Prerequisites

• Internet connection
• Familiarity with terminal
• CD/DVD RW drive

Procedure

Install Xorriso:

sudo dnf install xorriso -y

Write ISO to Disk:

sudo xorriso -as cdrecord -v dev/=/dev/sr0 -blank=as_needed -dao Rocky-10.1-x86_64-boot.iso

Additional Information

Xorriso relies on a C library libisofs. You can learn more about the libisofs on Fedora's package watcher.

Conclusion

In this gemstone you learned how to write an ISO to a physical disk with Xorriso! Keep in mind that Xorriso can be used to write other filetypes to physical disks, but I found it especially handy for hybrid ISO format that graphical tools didn't know how to deal with.
