In the resulting file selection dialog, navigate to and select the RHEL 8 installation ISO image and click on the ''Open'' button. After selecting the image, a dialog will appear within which the image can be written to the USB drive. Select the target USB drive from the device menu before clicking on the ''Write to Disk'' button:
Figure 13-2
Once the image has been written to the device, the device is ready to be used to perform the installation.
Figure 13-3
Use the arrow keys to navigate between the options and make a selection with the <Enter> key. If the ''Troubleshooting'' option is selected the screen shown in Figure 3-4 will appear including options to boot from the current operating system on the local drive (if one is installed), test the system memory, or rescue an installed RHEL 8 system. An option is also available to perform the installation in basic graphics mode for systems without a graphical console:
Figure 13-4
Select the option on the main screen to install Red Hat Enterprise Linux and, after a short delay, the first screen of the graphical installer will appear:
Figure 13-5
Select your preferred language on the first screen before clicking ''Continue'' to proceed to the main installation screen as shown in Figure 3-6:

Begin by selecting the ''Network & Host Name'' option, enable a network device on your system and enter a host name before clicking the ''Apply'' button:
Figure 13-7
If your network connection requires additional settings, click on the ''Configure..''. button to access the advanced network settings screen illustrated in Figure 3-8:

Once the host name has been defined and a network connection enabled, click ''Done'' to return to the main screen.

Use the left-hand panel to select a basic configuration and the right-hand panel to add any additional packages you know you will need after the system starts up. If the RHEL 8 system is intended to be used with a graphical desktop environment, choose either the ''Workstation'' or ''Server with GUI ''option. Otherwise, it is generally recommended to start with a minimal system and install additional packages as needed once the system has booted. This avoids installing any packages that may never be needed.

By default, the installer is configured to automatically install the operating system using the available space on the currently selected disk drive and to configure standard partition sizes. If the disk previously contained another operating system, these existing partitions will not be deleted, potentially leaving unused space on the drive after RHEL 8 has been installed. To remove any existing partitions so that they can be reclaimed and used by RHEL 8, enable the ''I would like to make additional space available'' option and click on the ''Done'' button to display the dialog shown in Figure 3-11.
Figure 13-11
To reclaim space, select a partition that is no longer needed and mark it for removal by clicking the ''Delete ''button. Once all the partitions that are to be removed have been selected, click on the ''Reclaim Space'' button to perform the deletion. The reclaimed space will now be used automatically by the RHEL 8 installer.

The manual partitioning screen provides the option to configure the disk using LVM) or standard partitioning. LVM is the recommended option because it provides flexibility in terms of managing partition sizes once the system is up and running (LVM is covered in detail in the chapter entitled ''“Adding a New Disk to a RHEL 8 Volume Group and Logical Volume”'''').''

Once the disk has been configured, click on ''Done'', review the summary of the changes to be made to the disk (Figure 3-14) and click on the ''Accept Changes'' button:

RHEL 8 also allows the contents of the disk to be protected by encryption. This will require a passphrase to be entered each time the system boots. To enable encryption, select the'' Encrypt my data'' option on the main ''Installation Destination'' screen and, after clicking the ''Done'' button, enter the passphrase in the dialog shown in Figure 3-15:

The root, or super-user account, is a special user that has administrative privileges on the system. While you will generally use your own account to log into the system, you will need to gain root privileges in order to configure the system and to perform other administrative tasks. Enter a root password, create a user account and wait for the installation to complete.

At the prompt, use the ''su'' command to gain root privileges:
