Horribly long boot on LL4 on SSD

[Roy]

Hello

I've installed a couple of week ago a fresh LL4 OS on my SSD
Everything was find and boots and startup was super fast
But now the system's load very slow.. it takes for it something like 02:20 minutes from pressing enter in GRUB until the first desktop sight
I tried running systemd-analyze blame as suggested on old post here to see what takes so long.. but the output wasn't satisfying

Also.. what is that vboxadd.service? I remember deleting virtual box as I don't really need it right now
I also tried to reformat my swap partition as it was suggested in some post
I did move my home partition to another hard drive
Can someone help? the internet isn't helpful that much this time...  :-\
