Hi! I've moved my SSD with an (up to date) EndevourOS - from intel i5 3570 to ryzen 5 3600 - quite the jump. It's not surprising that it's not booting - it's saying that no valid boot media has been detected.
I have important data on a separate home partition, so that's not a problem, but - is there a way to "update" the system from a live USB without a complete reinstall of the boot partition? I don't have my config saved, and I'd really prefer to not have to reconfigure and reinstall everything from scratch.
Is there a way to do it painlessly? Do I just chroot and do update-grub? I haven't really tried anything yet to not screw up by accident.
