Boot time

Boot time

   
Hi,
I recently installed Ubuntu 20.04 and it is super fast on my PC. It is not the dual boot. My PC specs are:
CPU: Intel Pentium [email protected]
Graphics: Intel G41(Onboard Graphics)
HDD: 250gb
Ram: 4GB + (4GB Swap)
But the boot times are very slow it takes about 1min to boot. At first it was about 30sec but now it is almost 1 minute. I checked boot time with systemd-analyze time it gave the results like this :
systemd-analyze time
Startup finished in 5.929s (kernel) + 51.893s (userspace) = 57.822s
graphical.target reached after 51.826s in userspace

And I did check with systemd-analyze blame and it showed like this:
$ systemd-analyze blame

Here the critical-chain results also:

The time when unit became active or started is printed after the “@” character.
The time the unit took to start is printed after the “+” character.

So how can I reduce my boot speed?
