Ubuntu – Bootable device not found after clean install of Ubuntu 14.04 UEFI on Acer


I have a single boot Acer laptop where I performed a clean installation of Ubuntu.

After boot it shows a bootable device not found error.

I tried running boot-repair and when it finishes it says that repair was successful, but the error persists.

The laptop did not have any operating system previously installed on it.

I also tried to deactivate UEFI, but the desktop would not load correctly making it impossible to install.

Any ideas on how to fix it?

I got it work at Acer Aspire ES1-111-C827. Should be working on other devices, too. Probably the BIOS-entries are a bit different. All you have to do is to register the newly installed UEFI-file as trusted for executing in BIOS-security options.

Before installation goto BIOS-Settings, make sure to have this:

  • Security: set supervisor password;
  • Boot - BootMode: UEFI;
  • Boot - SecureBoot: enabled;

After installation again go to BIOS-Settings

  • Security - Select an UEFI file as trusted for executing, press Enter;
  • HDD0 appears, press Enter;
  • EFI appears, press Enter;
  • Go to <ubuntu> and press Enter;
  • Choose the first entry with .efi (shimx64.efi on my device) and press Enter;
  • Give it a name and press Enter;

Save changes on exiting BIOS and restart. That's it.

Some people report that they still needed to change the boot order.
