Can you follow the "Boot options" instructions on the following wiki to
enable additional output on boot:

https://wiki.ubuntu.com/DebuggingKernelBoot

As mentioned on the wiki, it would be great if you can attach a log file
which may have captured any messages you see. If you are unable to
capture a log file, a digital photo will work just as well. As a last
resort you can even copy messages down by hand.
