(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.

Note that this is not just about the dummy grub install location
selector that is not used in EFI mode, but configuring one partition as
do not use, and the other as ESP in the manual partitioning screen.
