7.2. Creating a boot ISO installer image by using RHEL image builder in the GUI
You can build a customized boot ISO installer image by using the RHEL image builder GUI. You can use the resulting ISO image file on a hard disk or boot it in a virtual machine. For example, in an HTTP Boot or a USB installation.
The Installer (.iso) image type does not accept partitions customization. If you try to manually configure the filesystem customization, it is not applied to any system built by the Installer image. Mounting an ISO image built with RHEL image builder file system customizations causes an error in the Kickstart, and the installation does not reboot automatically. For more information, see Automate a RHEL ISO installation generated by image builder.
