The bootable USB media is now prepared for use in the installation of an operating system.
One of the PowerEdge Servers' front USB ports was used to connect this bootable USB drive. During POST, we chose F11 to access the Boot Manager.

Here Boot Mode is selected as BIOS Mode.
Select Legacy Boot option - Disk connected to front USB to start the operating system installation.
When the operating system installation selection appeared, we chose to start the installation by choosing Install Red Hat Enterprise Linux.
For demonstration purposes, we changed the BIOS from BIOS to UEFI Mode and follow the steps for operating system installation using the same bootable USB media.


Next, we disconnected the Bootable USB device from the Front USB port and inserted it into the PowerEdge Server's Back USB port. We then rebooted the server to begin operating system installation from the Back USB device.
