I found errors in my log which i've attached and went to reboot the server. Now i'm unable to boot and shows the following output. I've tried different USB 2.0 ports and still receive the same error.

 

It's says to 

Please append a correct "root" boot option; here are the available partitions:

 

But then doesn't show any options after that. I'm at a loss so any help would be appreciated.

 

This is usually a flash drive problem, try recreating it or using a different one.

Thanks, I did end up having to flash to a new usb drive and it's working now.
