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

Question

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?

Solution

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.

It also worked for me to do all the above steps after installation.

I followed the instructions; for some reason I don't get the 'Select UEFI file as trusted' option; although I can create the new boot with shimx64.efi as boot file; but it doesn't start the OS nevertheless.

Installing with UEFI (without CSM) and SecureMode, and then disabling SecureBoot and switching to UEFI (without CSM) after install made it work for me.
