I have Ubuntu 18.04 (Bionic) installed on 1 partition (ext 4) using whole disk. I want to downsize it with GParted running from live USB, but after resizing, 18.04 does not boot, showing lots of errors.
I was able to try several times, because I have an ISO image of the system and I recreate it after with Clonezilla.
What should I do?
