The point I wanted to make is that there isn't a single version number for KDE 5 anymore, the three parts (and maybe others) get updated and versioned independently.

So KDE 5 is "all of the parts", but a 5.x version only applies for Plasma or Frameworks (and they've got two different 5.x versions).

I tested KDE Neon on my Lenovo X380 laptop from the USB and it works without any problem, even if was a short test.

My PC (old HP 8100 Elite CMT) seems to have well recognized problems in booting from USB, so no test possible in this way.

Researching I discovered need to be possible to boot from a ISO file on my C drive using Grub2Win.
Installed I managed to change the boot configuration in this

Code:
#
#            This is sample code for booting from an iso file
#            via the Grub2Win g2wisoboot function
#
#            See the Grub2Win help file advanced topics section for more information
#
     clear
    set isopath='/neon-useredition-20181227-0531-amd64.iso'
     set kernelpath='/casper/vmlinuz'                 # Example '/vmlinuz'
     set initrdpath='/casper/initrd.lz'                 # Example '/initrd.img'
     set bootparms='boot=/ iso-scan/filename='$isopath' noprompt noeject'          # Example 'boot=/ iso-scan/filename='$isopath' noprompt noeject ---'
#
     g2wisoboot                                          # Run the g2wisoboot function
#
But attempting to boot I get stuck in a cycle error "Retrying nfs mount ... nfsmount: need a path".

Any suggestion to solve this so I can proceed with my test. Or there is another path maybe to install KDE Neon on a HDD partition I can later delete, without using USB istaller.

The "Retrying nfs mount ... nfsmount: need a path" message means it's looking for a NFS (Network filesystem) server to find the ISO image on for KDE Neon, so unless you have a NFS server, this won't work anyway. I can't tell from the code you posted above why it's looking for an NFS server, but I can only assume it's a part of the "g2wisoboot" function to look for one. And therefore it cannot find the ISO image on your local machine.

I'd suggest you just follow these instructions instead, to install it on your hard drive/SSD/whatever.

ehartman, I once again knew what you meant before, but it's beside the point once again. I think I'll just start ignoring what you say from now on - you're once again NOT helping anyone, please once again think of the OP, and future readers of this thread, and please grow up.

Thanks jsbjsb001.
Regarding that link he consider for installation a USB or DVD, neither of them I can use.
Grub4Win appear to be a solution but if I can't boot from ISO I can't also proceed with the installation.
About the error, the only thing I'm not sure about Grub4Win configuration is the bootparms, I have no clue what's need to be inside and didn't find documentation, so I just copied the example, maybe not relevant at all for my case.
Any suggestion about boot parameters for Linux?

Is this for your machine that can't boot to USB?

If so, you could try burning the ISO to a DVD and boot from that instead. The ISO's for the "User Edition" Edition of KDE Neon are here, and it does say on the downloads page that they are both the "install", as well as the "live" ISO's. So I can't see any reason why you cannot burn the ISO on to a DVD, and then run it as a "live" system from that.

I just tried to find the documentation for it (Grub2Win), and it looks like it only has a "discussion forum", and that's it.

I think burning the ISO on to a DVD would be the best option for you in all honesty.

I discovered in fact I can boot from USB drive, I only needed to enable MBR mode and not GPT as I have done before in Rufus.

KDE Neon load in my PC with just some errors but I was able to arrive to desktop and operate, but got another problem: since it's a Live USB any installation I've done needing a reboot will not show up the next boot.
I.e. I tried to install Nvidia drivers from "Software & Updates" app, but even if the app tell I'm using the custom driver in fact OpenGL utility tell me I'm still on Nuveau.

Enabling a persistent storage using Linux Live USB only work on supported distro, KDE Neon not being among them.
Currently preparing USB disk with Kubuntu, will see how will work.

Yeah, if you don't enable persistence, everything will be loaded into RAM, therefore any changes you make will be wiped out as soon as you restart or shutdown the machine. Good to hear you got USB booting to work. Just keep trying different distributions, then when you find one you like more than the others, install it onto your hard drive/SSD drive.

Tested KDE Neon, Linux Mint 18.04, and Kubuntu 18.10, all booted without problems.

Mint is nicer for the newbie, but in fact apart a more GUI based configurations this didn't changed the problems for the critical topics, aka Nvidia GPU. Also Kubuntu is definitely better than KDE Neon for the newbie, considering also KDE forum topic for Neon appear to be a bit dead.

I wasn't able to make any of them to use custom Nvidia drivers, but the point is I suppose without being able to reboot and maintain the config the new proprietary driver will not be used. I need to find a way to install it on a different partition on my old PC for testing.

Also tried to install KDE on Mint, but using the standard instruction

Code:
$ sudo apt install kubuntu-desktop kde-plasma-desktop kscreen
I got a compatibility error. So I tried to install it from the Software Manager, even if KDE Plasma version is outdated.
Problem is after the logout I choose the KDE DE, and the system asked me for a login. Tried root/kubuntu/mint / <blank> user / password combination with no luck. So I got more questions

1. There is a specific login/pwd for standard KDE installation?
2. I need to reboot to make the system use the proprietary Nvidia driver?

The problem with KDE on Linux Mint is that Mint's developers dropped their support for KDE, because apparently it was too hard for them to maintain support for KDE on Mint. So I checked for you, and as I was thinking, you would need to use Ubuntu's KDE packages to install KDE on Linux Mint. So it looks like you are on the right track, but may have missed a few packages/steps, try this guide. I think the easiest thing you could do to save yourself the trouble, would be to just use Kubuntu instead, which is basically Ubuntu with KDE instead.

How are you trying to install the NVIDIA drivers? From packages or from NVIDIA's website via their .run installer?

As the easiest thing to do would be to use packages, the added bonus is that you won't need to reinstall the NVIDIA driver when you update the kernel, which you will have to do if you use the .run installer from NVIDIA themselves, each time you update the kernel. I would strongly suggest you actually install the distribution you like the best to your hard drive/SSD drive before attempting to install the NVIDIA drivers.

Planning to install second SSD on the old PC so to properly install Kubuntu,and prepare for the new hardware properly.

About different versions I didn't understand if adopting 18.04 LTS I will get during the time the new features "tested" first in the 18.10, or I will need to wait for the 19.04. Reading appear this second is the case, the LTS receiving just bugfix but no new features. Need to familarize with backports as soon I will become more used to Linux.

Even if I appreciate DE more sleek features I'm worried mostly about elements useful for hw compatibility. Having the relatively new Ryzen Pinnacle Ridge cpu and chipset I suppose will be better supported during the time, want possibly to achieve this better hw support installing newer packages, if useful.

Installed Kubuntu 18.04 LTS and all worked, just needed to postpone updates after the installation to avoid problems.

Next step being testing Nvidia driver and Cuda compatibility I think my search is done and will also install Kubuntu 18.04 LTS on the new PC when arrive.

Thanks for all the useful information, was nice beginning in this way my Linux adventure.

18.04 will be supported longer for both bug fixes and security problems. 19.04 will be newer but only gets support for about 9 months, so in just a half a year or so you will have to update to 19.10 (and again half a year later to 20.04, which will be a LTS release again).
*ubuntu only has a Long Term Release every two years, which should be supported for 5 years (the KDE desktop itself for 3), all the other ones are short time (6 months plus a few for overlap to the next release).

Current kubuntu LTS releases are
Code:
14.04.5 (5th update) = Trusty Tahr - which will run out of support this year
16.04.5 (5th update too released) = Xenial Xerus
18.04.1 (had its first update recently) = Bionic Beaver - supported for at least 3 years
and 18.10 is the latest short term release, it is called Cosmic Cuttlefish and will be supported to july (this year)
