I recently bought an Acer Swift 3 ultrabook preloaded with Windows 10, which I wiped out to install Ubuntu 16.04.1 in single-boot. In my case installs are generally a breeze, but not this time. Long story short, I ended up with a «No Bootable Device» message on boot. I fixed the problem with Boot-repair. The ultrabook now works perfectly.
After the repair, however, I kept getting at boot time a blue window with this message : « Default Boot Device Missing or Boot failed. Insert recovery media and hit any key ». Hitting a key would lead me to a Boot Manager with only one entry : 1- Windows boot manager. Selecting it would then get me to Grub, with the usual Ubuntu option.
I searched the net, found this post, http://Bootable device not found after clean install of Ubuntu 14.04 UEFI , modified the BIOS-settings as instructed («Select an UEFI file as trusted for executing» and so on), to no avail. The blue rectangle just won’t go away at boot. The only change is that there is now a Ubuntu entry in the Windows Boot manager.
Secure Boot is enabled.
The boot priority order is :
1- EFI File Boot 0 : Ubuntu
2- Windows Boot Manager
3- HDD : HF S256G39TND-N210A
The output of
sudo efibootmgr -v can be found here: http://paste.ubuntu.com/23535154/
By the way, when I modified the BIOS-Settings in the Security tab, I found three .efi files in HDDO - EFI - ubuntu. I selected the first one (as suggested), and left the other two untouched: grubx64.efi and MokManager.efi.
I could ot course reinstall Ubuntu from scratch, but since I've already installed a whole bunch of applications, I’d rather find a workaround. Besides, I might end up in the same predicament since I still don't understand what I did wrong!
