Chapter 10. Installing RHEL using an ISO image from the Customer Portal

Use this procedure to install RHEL using a DVD ISO image that you downloaded from the Customer Portal. The steps provide instructions to follow the RHEL Installation Program.


When performing a GUI installation using the DVD ISO image file, a race condition in the installer can sometimes prevent the installation from proceeding until you register the system using the Connect to Red Hat feature. For more information, see BZ#1823578 in the Known Issues section of the RHEL Release Notes document.


  • You have downloaded the DVD ISO image file from the Customer Portal.
  • You have created bootable installation media.
  • You have booted the installation program and the boot menu is displayed.


  1. From the boot menu, select Install Red Hat Enterprise Linux 9, and press Enter on your keyboard.
  2. In the Welcome to Red Hat Enterprise Linux 9 window, select your language and location, and click Continue. The Installation Summary window opens and displays the default values for each setting.
  3. Select System > Installation Destination, and in the Local Standard Disks pane, select the target disk and then click Done. The default settings are selected for the storage configuration. For more information about customizing the storage settings, see Section 12.4, “Configuring software options”, Section 12.5, “Configuring storage devices”, Section 12.6, “Configuring manual partitioning”.
  4. Select System > Network & Host Name. The Network and Hostname window opens.
  5. In the Network and Hostname window, toggle the Ethernet switch to ON, and then click Done. The installer connects to an available network and configures the devices available on the network. If required, from the list of networks available, you can choose a desired network and configure the devices that are available on that network. For more information about configuring a network or network devices, see Section 12.3.4, “Configuring network and host name options”.
  6. Select User Settings > Root Password. The Root Password window opens.
  7. In the Root Password window, type the password that you want to set for the root account, and then click Done. A root password is required to finish the installation process and to log in to the system administrator user account. For more details about the requirements and recommendations for creating a password, see Section 12.7, “Configuring a root password”.
  8. Optional: Select User Settings > User Creation to create a user account for the installation process to complete. In place of the root account, you can use this user account to perform any system administrative tasks.
  9. In the Create User window, perform the following, and then click Done.

    1. Type a name and user name for the account that you want to create.
    2. Select the Make this user administrator and the Require a password to use this account check boxes. The installation program adds the user to the wheel group, and creates a password protected user account with default settings. It is recommended to create a password protected administrative user account. For more information about editing the default settings for a user account, see Section 12.8, “Creating a user account”.
  10. Click Begin Installation to start the installation, and wait for the installation to complete. It might take a few minutes.
  11. When the installation process is complete, click Reboot to restart the system.
  12. Remove any installation media if it is not ejected automatically upon reboot.

    Red Hat Enterprise Linux9 starts after your system’s normal power-up sequence is complete. If your system was installed on a workstation with the X Window System, applications to configure your system are launched. These applications guide you through initial configuration and you can set your system time and date, register your system with Red Hat, and more. If the X Window System is not installed, a login: prompt is displayed.


    If you have installed a Red Hat Enterprise Linux Beta release, on systems having UEFI Secure Boot enabled, then add the Beta public key to the system’s Machine Owner Key (MOK) list.

  13. From the Initial Setup window, accept the licensing agreement and register your system.
