[Bug 1396379] Re: grub2 does not install in the correct partition on efi system

[francesco florian]

i filed the bug exactly because i did so: i chose "efi system partition" in the 
partition selection section; it was already formatted as FAT and labelled EFI, 
but grub was installed in the wrong partition. (note: i'm quite sure i did the 
right thing because the same partition and process works in fedora)
i also noted that after changing the fstab, grub configuration files are saved 
in /boot/efi, but something else (i don't know what) in still installed in the 
wrong disk, as the bios (uefi) says ubuntu is in the first disk, not the second 
(the one where my /boot/efi is located).
thanks for you work

Title:
  grub2 does not install in the correct partition on efi system

Status in “grub2” package in Ubuntu:
  Invalid

Bug description:
  (k)ubuntu 14.04.1
  package version: 2.02~beta2-9ubuntu1

  i installed ubuntu on my external hard disk, where i also have a previously installed fedora system. i also have a windows 
  (efi-booted) system in the internal hard disk.

  at install time via ubiquity i get all grub configuration files in the first EFI-labelled partition (i.e. /dev/sda2 in my case) instead of the one i selected (/dev/sdb1).
  later i changed my fstab mounting /boot/efi on /dev/sdb1 and tried to reinstall grub package (apt-get install --reinstall grub-efi-amd64); now all grub configuration files are in the rigt place, but booting from the external hard disk still shows the fedora grub installation, while selectin the internal hard disk from the bios menu shows a submenu listing ubuntu and windows.
  explicitly installing grub in the correct disk (grub-install /dev/sdb; grub-mkconfig -o /boot/efi/EFI/ubuntu/grub.cfg) has no effect, nor it has running efibootmgr (efibootmgr -c --disk /dev/sdb --part 1).

  expected results: grub shoud have been installed in the disk/partition i chose;
  actual results: ubuntu always chooses the first disk to install grub on.
