Some answers (I was slow, as I do not use Unetbootin).

Like you, I have not used unetbootin for years. For some reason my copy of etcher will not run, and I have not yet found out why. I have etcher on both my desktop and my laptop, and it is refusing to run on both. (The desktop is running Linux Lite and the laptop is running MX Linux. Knoppix is only on the laptop.) I had to find and install unetbootin before I could use it.

I think I have found out what you have done, I investigated Unetbootin.
Question
"The first one is the default and tells me which
version of MX *[EM ???]  (this should read Knoppix Linux)* is
installed [EM 'on USB' ] and ready to start."

Does this start your normal hard disc with MX Linux? [And NOT Knoppix?]
I think it starts Knoppix!

Absolutely not. It is definitely Knoppix which is running

If so, then *that menu is a GRUB selection* for various versions of
Knoppix operating systems (32 bit, 62 bit, adriane ( a voice screen
reader option), knoppix64  (knoppix using a 64 bit kernel) etc. on the
bootable USB.

When you start Knoppix, you should never get your normal OS.
Only the Live Knoppix  system.

This is what I get.


My problem was how Unetbootin has loaded Live Knoppix to your USB.
As it is years since I used Unetbootin, I went for a YouTube Video on
it, and I now see what you get is the GRUB screen choices of Unetbootin
from *Unetbootin's GRUB menu*. [No picture attached, but you can se it
in video]

See YouTube Video:   https://www.youtube.com/watch?v=1xIR9KnLmvo
[Make a Bootable Knoppix/Linux Flash Drive]
about 2.22 minutes into video is the menu system.

Gives
heading "Unetbootin "  then

Default        [This is where Knoppix searches your machine and fits
                 its version to your hardware]
auto
knoppix
adriane
knoppix64
adriane64
debug
debug64
fb1024x760
fb800x600

The one you should use is knoppix64 as you have a 64 bit machine.
Now 'default' is ok as it will allow Knoppix to search for what fits
your machine. It should then chose what suits your hardware.

Playing the video, it goes past the boot adjustment line, without
showing how to select language.
However it shows in red on choice screen Press TAB to adjust entry.
I think this allows you to adjust boot line. It may be this that has
given you the F2  through F8 options. You only need the F2 (UK language)
and F3 to use as a LIVE LINUX *without persistence*.

F3 is actually the time zone.


As you have previously pressed F5 (with persistence) it will save
changes to Knoppix  for rebooting. Ok for Wifi settings etc, but it
means the safety of the Live Linux  as a non-writeable kiosk type
operating system is gone. Thus an attacker could write to the system, if
you can write to the system


The whole purpose of a LIVE LINUX Knoppix is NOT to put stuff on it as a
  "/home" but use it as  as a operating system which is 'frozen'  and
thus incorruptible. No persistence.
As a choice it allows persistence, but is less safe.

Without persistence, it is the best Linux for internet banking, buying
etc. as no 'bad guy' can write to or access your data on it. Its
firewall is set somewhat rigidly to not allow incoming-writing data.
I teach my pupils (seniors) to use it for banking.

If any work done in Live Linux Knoppix is to be saved it is saved OFF
the Knoppix USB to another  disc , usually another USB.
Quote
I have not yet found out how to copy my home folder over, or at least
some of it. Just some of the profile files would be useful.
Unquote

You should NOT copy over your "/home" folder
If Knoppix is operating from its own USB, you will find it has found any
other internal discs (i.e. you main operating system for that machine
and "/user/home") on that machine and can show them, and access and
write to or read from these other discs.

One problem I have is when it asks me for a password. In Thunar there is an item named livemx. When I try to look at it, it asks me for the root password. I do not remember setting up any password while installing Knoppix. I have tried several likely passwords, but to no avail. Any ideas please?



I think you have a workable Knoppix USB using Unetbootin's GRUB boot
loader. That is why 'default' without any adjustment of boot line (edit
line by tab) gave you a USA keyboard. (The default keyboard for EN
versions of Knoppix is USA keyboard).

Check your USBs
Once you have booted into Knoppix, you can into another USB slot and
insert your problem USB keys, if opened in file manager, UNMOUNT, then
start GParted  from Knoppix to examine the problem USB.
Gparted is in menu section preferences. It is the lowest menu line choice

I trust this helps.

Aside.
I have one laptop (experimental and old) 2-internal-hard disk machine
which dual boots Windows Vista or Knoppix from its two internal hard
discs, one on Windows , one on Knoppix, but the prior formatting of a
Knoppix hard disk is a serious matter [learn how to on a search engine]
(as it uses btrfs for OS), there is an 'experimental' "Knoppix OS to HD"
[hard disc]" choice in knoppix menus but sometimes it does not work.

Let me know how you get on.

Thanks for all the time you have spent with me so far. I am obviously only about half way there so far. Perhaps I should start by getting etcher to work properly. A newer version perhaps. Never had any problems until just recently.

Thanks a lot,

Neil
