I apologize to everyone, but I was very angry when the system crashed.
That's quite understandable.
It takes a great character to reflect and to apologize.
Only the fewest are great enough of doing this.
So, kudos for apologizing.
Apology accepted.
Removed you from my ignore list.
I don't think I did anything wrong; I'm just an enthusiastic, inexperienced newbie who, when things go wrong, complains and asks for help like this.
Well, obviously something went wrong - what and for which reasons, we will see step by step.
You need to work on your way how to complain and ask questions. You already saw that yourself and started working on it. Good.

Since here we are no Linux forums. See
Sysadminotaur #151 for details.
So, now, let's get your feet on FreeBSD.
You will agree, it's worth it.
Maybe in a few weeks you will help newbies to get into it.
As you already realized, FreeBSD ain't no tinkertoy.
You are dealing with something on a professional level.
Even if many here using FreeBSD not for professional purposes, while a lot many others do, the system itself requires some professional ways of looking at and dealing with things.
Still in general terms this means two things:
1. Eyecandy can be added optional, if wanted. But by default the barest minimum for UI is delivered just to be capable to do the job needed to be done as comfortable as possible. It is comfortable.
You shall not confuse things of what you are used to with comfy. Personal tip by me: Don't compare too much. Start freshly new all over. You save yourself lots of, 'Why ain't the shit not more like...' Well, it's not. Just use it as it is. It's highly probable you will find out: You simply was not just not used to it yet. But once you are, you will say, 'That's better.
WAY better!'

You'll learn in many ways FreeBSD is way less complex and more reliable than many Linux, maybe even better. It depends on, what you want and expect. At least many FreeBSD newcomers had this experience, like myself, when I switched completely from Windows to FreeBSD app. 6 years ago.
Looking nice is of no importance. Silly example: If you need to know what 3 * 4 is, you just need to know it's 12. how the 12 is presented, doesn't matter. If it is some simple UTF-8 characters in a shell output or some GUI toy looking like some 1990's LCD desktop calculator gives you neither more nor less information about what you actually all you want to ḱnow, namely it's 12.
2. Learning is mandatory. FreeBSD ain't not autoinstalling turn-key OS. Such is only suitable for single user desktop machines with a prepicked and preconfigured desktop environment. You will comprehend that this wasn't a good idea for a multipurpose OS like FreeBSD, which means it can also be used for embedded systems or headless servers. So you are free to pick X, Wayland or none GUI at all, and if which DE or WM you wanna use.
For that, learning is required. At least the learning what choices there are, what you want to pick, and how to install and configure it. FreeBSD is meant for tailoring individual systems. Perhaps think of it like 'creating your very own personal "distro".'
And because of GUI is only one single point about the whole show, doesn't make the things more trivial. But once you grasped the idea how to add moduls in general, which ain't rocket sciences, you can add any modul.
For that FreeBSD comes with an exemplary handbook, which covers everything at least a common user needs to get a personal desktop computer up and running. What's missing there is covered here in this forums And other sources, like man pages, books, how-tos, personal websites etc. Tip: Not only the
man pages under FreeBSD cover all what's needed - it's worth to search them also for general topics, but
file:///usr/local/share/doc/ on your system is a goldmine.

(copy paste it into your browser's address bar, since I cannot create a link here to a directory on your computer

.)
Coming new to Unix first means to learn what documentation there is, where to get it, and which to use when for what. (Another point why Linux ain't no true Unix, because they often refuse to do documentation.


)
And of course, read it.
My recommendation was you start by at least skim the
FAQs (actually worth a peek). Cost you ten minutes at most, and gives you a lot ideas about the whole show.
Then start reading at least the beginnnig (abstract, introduction, chapter 1,...) of
The Handbook until at least how to install FreeBSD with a GUI.
You want to install FreeBSD as second or third OS on a disk. That's already quite a challenge for the start. So search the forums. You are not the only one booting more than one OS from one drive.
I'll bet you will have FreeBSD up and running with a DE and some Apps installed in a few hours.
I wrote some posts for newbies to FreeBSD (so did others, of course. You will find when you search the forums. Tip: use
duckduckgo.com for searches like, 'FreeBSD dualboot'. Most of the times you get better hits there than using the forum's internal search.)
You can find and browse the stuff I wrote on this forums,
when you click on my avatar, go to my personal site under "About". But you don't have to read all that junk, of course.
And if you learned how to ask right - and it seems that's now the case

- you will get your answers here.
Enjoy FreeBSD, and again, Kudos for apologizing!
