Delay is likely caused by hardware limitations, since a classic hard-drive is used. For a more detailed diagnosis, more information on the application in question and other relevant stuff is needed.
For example the output of
systemd-analyze blame
systemd-analyze critical-chain
in a decent formatting might be helpful.

Please use 3 backtics(```) before and after the code to format it, the preview can be seen on the right-hand side.
Also, your systemd-journal-flush.service is taking time, try to clean your journal logs using:

sudo journalctl --vacuum-size=64M

Also, boot times close to 2 mins are to be expected in HDD( I use HDD too!). And be ready to see the bouncy animation a few times.
