[Bug 1213119] Re: "You need to load the kernel first" when trying select any option from grub list when using EFI

[Shaun Turnbull]

Sorry for slow response; keep on getting lost here in the  depths of
Launchpad. I posted a picture to another Ask Ubuntu question.
http://askubuntu.com/q/298819 and trying more recently gives similar
results with main difference being cd0,apple1 and cd0,apple2 are found.
I will see about borrowing a camera to get a better representation of
what is actually happening currently. The only thing that i have done
that may have had any influence on this is installing rEFInd (which
installs its own efi iso.9660 drivers) and burnt a new disc (due to cat
taking a walk on my disc when it was left lying about).  The same .iso
was used so this should not be relevant.  checksums have been checked on
.iso and veryified disk when burning.  This is all using 13.04 Desktop
amd64.iso.

Getting to the black grub screen indicates liveDVD has booted EFI mode
but iIt is when a kernel is selected i get the "can not read file" or cd
and "you need to load the kernel first" errors.

Using lsefisystab also confirms system is booting live DVD EFI mode.
Will do this again and try to report actual outcome.

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.
