After some manipulations with the fdisk utility, my Ubuntu system began to boot for a long time - everything was fine before. I can't figure out what happened and how to get back to the previous state. Also I should note that I don't have any other problems. Please explain me how I can investigate my problem and understand what is happened. Below is more info about my system, boot log and etc.
In my boot log I see : "A start job is running for /dev/disk/by-uuid/BA7A-9BA0 (10s / 1min 30s)". I seems to me that jos is related to /dev/nvme0n1p2(hard disk).
