Kubuntu 19.10
I deleted a different distro on the same disk as Kubuntu, it was before Kubuntu (i.e., to the left) and now I have a longer boot time. The perceived delay is after I see the Kubuntu logo. The system is i5 running on SSD with 8 Gb RAM.
Maybe something with fstab, and UUIDs that changed? I will post some info that might help

The solution requires two steps.
Remove from fstab the partition(s) that no longer exist. To do this, run
blkidin the terminal. Then open/etc/fstabwith root privileges and look for the UUID(s) that were not listed byblkid. Delete the line(s) that contain those UUID(s). Save and close.Run this command in terminal:
That should fix it. AFAIK this second step is required only in the Ubuntu-type distros.
