Red Hat Summit6장. Booting the installation media
You can boot the Red Hat Enterprise Linux installation by using a USB or DVD media and begin the installation process.
You can register RHEL by using the Red Hat Content Delivery Network (CDN). CDN is a geographically distributed series of web servers. These servers provide, for example, packages and updates to RHEL hosts with a valid subscription.
During the installation, registering and installing RHEL from the CDN offers following benefits:
- Utilizing the latest packages for an up-to-date system immediately after installation and
- Integrated support for connecting to Red Hat Lightspeed and enabling System Purpose.
In RHEL 10, the Defense Information Systems Agency (DISA) Security Technical Implementation Guide (STIG) and other security profiles do not automatically enable Federal Information Processing Standards (FIPS) mode at first boot. To remain FIPS compliant, you must manually enable FIPS mode before the installation begins, either by adding the fips=1 kernel boot option or by using a Kickstart configuration that explicitly enables FIPS. If FIPS is not enabled before installation, systems built using these security profiles might not be compliant, and users might unknowingly deploy non-compliant systems. To avoid compliance issues, ensure that FIPS is enabled during the boot phase, prior to launching the graphical or text-based installer. For more information, see Switching RHEL to FIPS mode.
Prerequisites
- You have created bootable installation media (USB or DVD).
Procedure
- Power off the system to which you are installing Red Hat Enterprise Linux.
- Disconnect any drives from the system.
- Power on the system.
- Insert the bootable installation media (USB or DVD).
- Power off the system but do not remove the boot media.
Power on the system.
You might need to press a specific key or combination of keys to boot from the media or configure the Basic Input/Output System (BIOS) of your system to boot from the media. For more information, see the documentation that came with your system.
The Red Hat Enterprise Linux boot window opens and displays information about a variety of available boot options.
Use the arrow keys on your keyboard to select the boot option that you require, and press Enter to select the boot option. The Welcome to Red Hat Enterprise Linux window opens and you can install Red Hat Enterprise Linux by using the graphical user interface.
The installation program automatically begins if no action is performed in the boot window within 60 seconds.
