After upgrading to v4.1.0, I can see the nbi after option booting but as soon as I select it, the mac sits in a frozen state for about 20 seconds before it decides to boot to the already installed OS on the internal hard drive. Any clues on what the problem could be? I even tried downgrading back to v3 and the issue appears to be here to stay. There were no issues before the upgrade to v4.1.0. Has anyone else experienced this?
Thanks
