I am currently trying to do a completely unattended Ubuntu install with preseed, following AskUbuntu automated install instructions.
Everything works fine on VirtualBox (I am simulating a DVD) but when I try to burn my ISO on a USB stick and boot it on a computer (UP Squared with Intel CPU), it doesn't boot !
I'd like to add : I have no problem with my bootable key when using a standard ubuntu installation. On the discussion I linked above, best answers says to "burn it on a DVD". Is there a difference between a burn DVD and a bootable USB key ?
Thanks in advance.

to make it a hybrid iso file? In that case it should work to clone it to a working USB boot drive. See this link.
