i performed a fresh installation of ubuntu 14.04 amd64 from a usb device as my only operating system, on a new hard drive device. i've tried many uefi combinations after reading Installing Ubuntu for Single Boot with a Random Boot Mode, and installing ubuntu in each combination but wasn't able to boot natively into ubuntu.

right now, secure boot and fast boot are enabled and disabled respectively on my machine. each time i boot, i have to launch the boot option, select ubuntu from the list of: os boot manager, boot from efi file, (and finally) ubuntu -- only then i am able to boot into ubuntu.

also tried boot-repair, which produced this log. by examine it, i decided to try and install grub again, by executing sudo grub-install /dev/sda, but it didn't help either.

i came across the following links, but non of which helped: Booting into Ubuntu after Fresh Install of Ubuntu 14.04 LTS ( No Dual Boot ) on Acer Aspire ES1-512 and https://askubuntu.com/questions/544823/problems-installing-ubuntu-on-hp-elitebook-840

can anyone shed the light on the issue?

Try this:

  1. Boot to Ubuntu using the ubuntu option in your boot menu.
  2. Open a Terminal window.
  3. Type sudo cp -a /boot/efi/EFI/ubuntu /boot/efi/EFI/BOOT
  4. Type sudo mv /boot/efi/EFI/shimx64.efi /boot/efi/EFI/bootx64.efi

If that doesn't work, please edit your question to include the output of the following commands:

sudo efibootmgr -v
sudo find /boot/efi -iname "*.efi"

the following worked for me:

  1. enter the bios setup, and head to the boot option -- disable secure boot, fast boot, and pxe boot. and set the boot mode to legacy. save and exit.
  2. install ubuntu (i did so from a usb drive).
