Linux Mint 18 was installed on an Intel NUC5i7RYH computer. That PC has a hardware problem so I moved the Samsung EVO 960 SSD to a new NUC7i7BNK, but the second NUC does not boot from the EVO SSD. It does see it in the BIOS as a boot device, and I can boot from an Live USB Flash Drive with Linux Mint installed. How can I boot the second NUC from the EVO SSD?
This fixed my problem. I installed and ran
sudo apt-add-repository ppa:yannubuntu/boot-repair sudo apt-get update sudo apt-get install -y boot-repair boot-repair
