Thanks, k.jacker! I think you got it to work!
I just went through the install. One question: Would it matter if I removed the USB stick when I was at this screen before hitting ENTER on Reboot?
That's what I did (removed the USB stick first) and some message then appeared on that screen, but I was still able to hit ENTER to Reboot. Then when it was trying to reboot it kept scrolling the same text for about 10 seconds (infinitely), so I just hit the power button. Then I hit the power button again and was greeted with the FreeBSD Boot Loader Menu:
I waited for it to count down and then entered my username and password. The only thing is in the handbook (at the bottom of this page:
https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/bsdinstall-post.html), it says: "If sshd was enabled in
Figure 2.46, “Selecting Additional Services to Enable”, the first boot may be a bit slower as the system will generate the RSA and DSA keys. Subsequent boots will be faster. The fingerprints of the keys will be displayed, as seen in this example."
I don't believe I ever saw this and I do believe I had sshd enabled. Do you think I did something wrong by removing the USB stick BEFORE hitting Reboot and then manually powering down the computer and turning it back on when it got stuck in some weird loop?
If not, I would like to know how to go about installing Xorg and Xfce. Can I just skip chapters 3 and 4 of the Handbook and go straight to Chapter 5: The X Window System?
