+
+## 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**:
+
+   ```bash
+   sudo dnf install xorriso -y
+   ```
+
+**Write ISO to Disk**: 
+
+   ```bash
+   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](https://packages.fedoraproject.org/pkgs/libisofs/libisofs/index.html).
+
+## 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.
