I am trying to get a dell power edge 1550 to boot off cd or USB so I can install CentOs. I created a CD with a CentOs ISO on it but the system won't recognize it. Even when I set the settings to only boot from CDrom. I then used UNetbootin to create a USB thumb however that didn't work either because their is no way to set the system to boot from USB.
The USB is turned on under integrated devices but it won't allow me to select it in the boot from menu.
