[Bug 1100247] Re: Unable to install Ubuntu on laptop without enabling Legacy mode

The error shows that it's trying to boot grub-efi, and can't find the
modules for it.  If the installer was booted in CSM mode, this /should/
cause the installer to install grub-pc, not grub-efi; so I wonder if one
of your other install attempts installed grub-efi, creating an EFI
system partition, and the post-install reboot is loading this grub-efi
from the EFI partition instead of grub-pc from the MBR.  You could try
deleting EFI/ubuntu/grubx64.efi from the machine's disk, and see if that
makes a difference?

  In order to confirm that USB key visibility was not a hardware issue,
  I created a Win8 recovery USB key which is correctly seen by the
  laptop and can be booted from. An image of the key can be  made
  available.

  FInally, the laptop is an Ubuntu certified laptop (pre-load only) :
