Slow Boot Time

[txm0523]

I did try the recommendation you posted, but it did not help. Vbox service still active, even after unchecking in the Startup options.
On my PC I dual boot Linux Lite and another Linux distro.I deleted that distro off the partition and utilized the Boot Repair function of Linux Lite, then rebooted.Boot up time is a little bit faster, so I ran the Systemd-analyze Blame from the command line againHere is what came up:
systemd-analyze blame
        17.881s vboxadd.service
        12.986s plymouth-quit-wait.service
        12.083s keyboard-setup.service
        11.809s ufw.service
        11.565s dev-sda5.device
        11.019s systemd-journal-flush.service
          5.484s motd-news.service
          4.611s NetworkManager-wait-online.service
          3.564s grub-common.service
          3.417s accounts-daemon.service
          3.208s ModemManager.service
          3.170s NetworkManager.service
          2.415s networkd-dispatcher.service
          2.106s systemd-udevd.service
          2.081s udisks2.service
          1.760s thermald.service
          1.759s apport.service
          1.755s console-kit-log-system-start.service
          1.721s systemd-logind.service
          1.697s alsa-restore.service
          1.692s lm-sensors.service
          1.692s avahi-daemon.service
          1.691s rsyslog.service

So, it appears that somehow dual booting was causing the problem ?  I don't know.Also, don't know why vbox service still pops up, although with a much shorter time limit even after running those commands and unchecking vbox service in the Startup options.Does this mean it's resolved or is there something else going on ?
Thanks,
