No bootable device error message on UEFI after installation
In my case some UEFI params needed to be set in the BIOS. I followed these instructions:

Here is a short description of the steps.
Step 1: Go to BIOS (with F2)
Step 2: Turn ON Secure Boot (You might need to set BIOS password before doing this)
Step 3: Select an UEFI file as trusted for executing: HDD0 -> EFI -> ubuntu -> shimx64.efi
Step 4: Add a description and confirm. Save BIOS settings and reboot.
BTW, later I discovered that when Secure Boot is turned ON that Linux won't recognize WiFi hardware, so I needed to turn it OFF.
