"Try Ubuntu" menu appears after installation on Acer Aspire ES 11-131 - without live USB I get "no bootable device"

Question

I've installed Ubuntu 16.04 on my Acer Aspire ES 11-131 laptop.

I choose to Erase Windows 10 and install Ubuntu. My laptop was way too slow in Windows 10, so I just wanted to get rid of it.

My problem is that whenever I switch on the laptop the Ubuntu GRUB menu doesn't show the Ubuntu OS. It only shows

Try Ubuntu
Install Ubuntu
OEM install
disc repair

If I boot without the live USB I get no bootable device found.

I have installed in UEFI mode only and have run boot repair, clicked recommended repair but it didn't fix the problem. Boot repair said

Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/shimx64.efi file

Run boot repair again, and get the info summary, and [edit] your question to include it. See possibly Installed Ubuntu 17.04 and now can't boot at all: Failed to open \EFI\Boot\grubx64.efi - Not found Install Ubuntu on unbootable Acer Aspire E5-575 "Default Boot Device Missing or Failed." — Zanna, May 17 '18 at 07:01
According to oldfred's answer you need to enable the supervisory password first (don't lose it...) - after doing that you might be able to "Select an UEFI file as trusted" and boot repair wants you to select the shim one — Zanna, May 17 '18 at 07:47

Turn on Secure boot from under Boot Tab.

Go to the Security tab and look for Select an UEFI file as trusted for executing and select enter
Navigate to shimx64.efi and press enter.

Might be something like this.

Save changes and exit. Now you should be able to boot.
