If you are installing Linux using Oracle System Assistant, and you have configured the system to use UEFI Boot Mode, after you select the target drive, the installation might fail.
Workaround
Log in to the Oracle ILOM web interface.
Select System Management > BIOS > Settings > Reset to Defaults > Factory.
Reboot the server.
The system boots and resets the BIOS settings to factory defaults.
To change the boot mode back to UEFI Boot Mode, select Boot > UEFI/BIOS Boot Mode, and then select UEFI from the drop-down menu.
Alternatively, if you have backed up your BIOS settings, you can restore the BIOS settings from the backup.
Boot to Oracle System Assistant and retry the Oracle System Assistant assisted Linux OS Installation.
