Bug description:
* Ubuntu 12.04.2 LTS "Precise Pangolin" - Release amd64 (20130108)
precise-desktop-amd64.iso from http://cdimage.ubuntu.com/precise/daily-live/current/ .
* Package Version
grub2-signed 1.9~ubuntu12.04.2+1.99-21ubuntu3.7
* Reproduce Steps
1. Use `usb-creator-gtk` to create a bootable USB drive by precise-desktop-amd64.iso
2. Use this USB drive to boot "Try Ubuntu without installing" on an UEFI secure boot enabled laptop.
3. Create only one 1GB primary fat32 partition on the disk of the laptop with GPT-based disk layout.
4. Mount fat32 partition on /mnt
$ sudo mount /dev/sda1 /mnt
5. Manually copy all contents from the USB stick into the fat32 partition.
$ sudo cp -av /cdrom/.disk /cdrom/* /mnt
6. Set up the EFI boot entry.
$ sudo apt-get install efibootmgr grub-efi-amd64-signed shim-signed
$ sudo grub-install --removable --uefi-secure-boot --root-directory /mnt /dev/sda1
$ sudo efibootmgr -c -d /dev/sda -p 1 -l "\\EFI\\BOOT\\BOOTx64.EFI" -L recovery
7. Append 'from recovery partition' to every menuentry title in /mnt/boot/grub/grub.cfg .
8. Reboot and select the boot entry 'recovery' from UEFI boot option menu.
* Expected Result
We can see every menu entry of grub with the suffix 'from recovery partition'.
* Actual Result
There is no suffix 'from recovery partition' on menu entries of grub.
P.S. The USB drive is still plunged in the laptop. After we unplug the
USB drive and select the boot entry 'recovery' from UEFI boot option
menu, we can see every menu entry of grub with the suffix 'from
recovery partition'.
