Hey Matt, there is no, "syslinux.cfg", file in the,"flash", directory.  Do I create one?  Do you mind posting the modified syslinux.cfg file here and where to put it? I am running Dual Boot on a Haswell Chromebox. 

I don't have a box configured for dual boot handy, so these instructions may need some massaging:

- boot ChromeOS, open shell
- mount LE system partition:
  -- mkdir /tmp/system
  -- sudo mount /dev/sda6 /tmp/system
- edit file:
  -- sudo vi /tmp/system/syslinux.config 
  -- go to end of file (should end in 'quiet'), hit i for insert, then type ' pci=nomsi', then ESC, then !wq <enter>
- unmount partition
  -- sudo umount /tmp/system
  -- note: umount, not unmount
- reboot into LE 

Thumbs up, Matt! The only change in your instruction, for me, is my file is called, "extlinux.conf", rather than, "syslinux.cfg", on my system.  Here are the contents of that file:

DEFAULT linux
PROMPT 0
LABEL linux
KERNEL /KERNEL
APPEND boot=LABEL=KERN-C disk=LABEL=ROOT-C tty quiet pci=nomsi

Thanks again for your help.
