A Lenovo tech came yesterday to replace the motherboard on my Thinkpad T440. I have Ubuntu 16.10 (or is it 16.04, can't remember) installed on a LUKS encrypted SSD. It was working fine before the motherboard replacement but now it won't boot. It won't even get to the GRUB screen.
I can mount the SSD on another Ubuntu computer and access my files so I know it's still there. The boot partition still exists as well but I'm not sure if it's somehow been damaged. I booted from an ubuntu livecd and tried running boot-repair but it didn't seem to have any effect.
When I turn on the computer it just keeps asking which drive I want to boot from, as if it can't find any bootloader or OS.
Any ideas? I have heaps of uni work on the SSD and although I've already backed up individual files there's no way for me to export data from my programs without booting it.
Please help!
