Dell PowerEdge Systems Red Hat Enterprise Linux 9 Installation Guide

Installing or reinstalling Red Hat Enterprise Linux 9

Important information before installing

Select the boot mode to be used for the system during installation. There are two boot modes available on Dell PowerEdge servers.
  • BIOS
  • Unified Extensible Firmware Interface (UEFI)
CAUTION Back up all the data from the system before installing or upgrading RHEL 9.
NOTE The boot configurations of UEFI and BIOS are different. Therefore, the installed system must boot using the same firmware that was used during installation. You cannot install RHEL 9 on a system that uses BIOS and then boot from a system that uses UEFI.

To install or reinstall RHEL 9, use one of the following media or methods:

  • Install with Lifecycle Controller (LC)
  • Install on iSCSI storage
  • Install using software iSCSI initiator
  • Install using hardware iSCSI initiator
  • Install on Fibre Channel over Ethernet (FCoE) enabled storage
