I have an Acer Aspire E 11 E3-112-C6YY which shows the same probably-
buggy firmware behaviour.
As Peter found, it'll boot from an Ubuntu USB mass storage device
without a problem, but will never show an Ubuntu installation on the
same EFI system partition as Windows Boot Manager. But it will reliably
show the "Unknown Device" in the same menu when it is reentered
awkwardly from GRUB: F12, select USB HDD, c, exit, <boots into USB GRUB
automatically>, c, exit, <same boot option menu, but this time with
"Unknown Device" which boots to the HDD GRUB>.
Putting ubuntu in BootOrder doesn't work, but BootOnce does. I haven't
completely verified that BootOrder is respected properly in general, but
it seems to be (eg. putting USB HDD above Windows Boot Manager). I also
haven't yet tried adding/removing RC, renaming ubuntu to Windows Boot
Manager, removing Windows Boot Manager from the EFI system partition,
using a separate EFI system partition, or removing Windows entirely.
When all boot options are exhausted it will automatically enter some
Windows repair thing. I'm not quite sure how that works yet.

Title:
I can't boot ubuntu after installing it dual-boot from kubuntu 14.10
CD prallel to windows 8.1, UEFI secure boot, on an Acer Aspire E15.
Status in efibootmgr package in Ubuntu:
Incomplete
Bug description:
However I can boot into the newly installed Kubuntu 14.10 folling the
followinf procedure:
-> starting with installation cd
-> swiching into boot grub boot promp
-> typing exit.
--> then i can select booting from the hard-disk.
Booting without live CD directly boots Windows, pressing F12
gives me a lelection where i can only select Windows.
Any help?
Best regards,
Peter
