Well, a few days ago I thought that it was end of my adventure with FreeBSD, but now I'm happy to report that I seem to have a stable installation of FreeBSD running on my computer again, I think that I understand why my desktop failed the other day, and I think that I now have a better back up method than what I had just a few days ago. Also, I'm too lazy to replace my FreeBSD installation with Linux Mint, or Zorin, so I think that I will continue using FreeBSD for the meanwhile. Also, I learned a little bit from this incident, and I now think that if a similar incident were to happen in the future, I'm pretty sure that I could handle it without have to do a reinstall and restoring from a backup. Looks like I'm married to FreeBSD for at least the near future.
