So you did a dual boot ChromeOS + OE install, and that works, but you can't bring up the boot menu to boot an external drive?
Your screenshot shows me the dev boot screen, which is normal for a dual boot setup. It also shows me that you have set the boot flags to legacy boot default + 30s delay, which is fine.
As per the wiki, if you see the 'Press ESC for boot menu' text, but the boot menu does not appear when you press ESC, then it's a keyboard issue. If you don't see the text, then it's an issue with your connected media.
