 I guess the Dell Recovery Media just takes longer to boot and has a meaningless
prompt to select from a non-existent menu. It finally came up in recovery mode
from the USB. In Ubuntu 16 fdisk still does not like it... 

In any case it looks like I can make recovery media now so should be able to make 
something work with Beaver on all the machines now.  
I just need to try make a dual boot USB device as I have tied up the 64Gb
stick on a few Gb boot.  If I make the Beaver disk can I  make another partition,
put the Dell recovery image there and kexec into it from Beaver or something? 

How is the Beaver iso assembled? I guess I could get that code and modify
it as needed as it is easier to work that way than with dd and disasembly lol.
