第4章 Creating a bootable installation medium for RHEL


You can download the ISO file from the Customer Portal to prepare the bootable physical installation medium, such as a USB or DVD. Starting with RHEL 8, Red Hat no longer provides separate variants for Server and Workstation. Red Hat Enterprise Linux for x86_64 includes both Server and Workstation capabilities. The distinction between Server and Workstation is managed through the System Purpose Role during the installation or configuration process.

After downloading an ISO file from the Customer Portal, create a bootable physical installation medium, such as a USB or DVD to continue the installation process.

For secure environment cases where USB drives are prohibited, consider using the Image Builder to create and deploy reference images. This method ensures compliance with security policies while maintaining system integrity. For more details, refer to the Image builder documentation.

4.1. Installation boot media options

There are several options available to boot the Red Hat Enterprise Linux installation program.

Full installation DVD or USB flash drive
Create a full installation DVD or USB flash drive by using the DVD ISO image. The DVD or USB flash drive can be used as a boot device and as an installation source for installing software packages.
Minimal installation DVD or USB flash drive
Create a minimal installation DVD or USB flash drive by using the Boot ISO image, which contains only the minimum files necessary to boot the system and start the installation program. If you are not using the Content Delivery Network (CDN) to download the required software packages, the Boot ISO image requires an installation source that contains the required software packages.
