The location is of course /cdrom/boot/grub/grub.cfg.  Other research may confirm this is a firmware issue.  The firmware version is EFI 1.1 rev 2 which rEFInd sees as UEFI 2.1.  Due to not being able to boot any grub options from grub list (grub boot manager loads but grub bootloaders will not boot) when booted using EFI mode the grub.cfg is when booted using Non-EFI mode.  Which is BIOS on this system due to not having CSM as this is an emulated EFI layer!(opposite of CSM which is full UEFI with emulated BIOS)
Canonical BIOS/UEFI Requirement documentation explains Ubuntu is geared to use UEFI 2.3.1 as described in the first paragraph of section 9 in this [Canonical Document]( http://hwe.ubuntu.com/docs/ubuntu-bios-uefi-requirements.pdf)

Title:
  "You need to load the kernel first" when trying select any option from
  grub list when using EFI

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  This affects Precise, Quantal and Raring on ga a75 ud4h  hardware.  This is not a Secure Boot capable system .  
  Trying to install using EFI mode when Windows installed using GPT already.
   EFI has to be switched off to allow installer or live session to run.  Both default and fallback installers not working when EFI is on. No options from grub list boot - get "can not read cd0/files" and "You need to load the kernel first" errors.  

  Have asked this http://askubuntu.com/q/208405/102029 question and
  tried to list some observations at
  http://ubuntuforums.org/showthread.php?t=2149013.

  After installing using the workaround of switching EFI off and then
  creating grub_bios partition to allow installtion bios mode. Then
  installing of grub-efi needs other modification to existing boot
  loader for Ubuntu to boot.  This is due to firmware hardcoding by
  vendors.  Boot-Repair fixes things to get going but through time
  system deteriorates and becomes unrecoverable or bootable due to
  mountall errors.
