Thank you GreyGeek for your answer.
I'm sorry if I havn't been clear enough:
- The second to last time, I couldn't boot after the installation of Kubuntu 16.04 crashed.
- But after the last try which also crashed I can still boot. I have the choice between Kubuntu 14.04 and Windows.

I tried both times to install Kubuntu 16.04 on sda8. A swap should therefore have been automatically installed on sda7, but the computer might crashed before.
In both cases, the bootloader should have been installed on sda.

Do you mind, that my grub is not healthy?

[GreyGeek]

You have Kubuntu on sda6 with EXT4 whichonly occasionally boots.
You apparently have attempted to install Kubuntu on sda8 but it didn’t get successfully added to grub because you didn’t save grub to sda2, the only boot partition you have.

Redo your Kubuntu 16.04 (?) installation to sda8 and save grub to sda2

If that fails the use a boot repair isotope fix your boot issues

[nicrnicr]

Thank you very much GreyGeek.
I will apply fasck to ext4 and write the results. Then I will try to install Kubuntu 16.04 on sda8 and save grub to sda2.

[GreyGeek]

Why not just use 18.04 instead, that way you won't have to upgrade next year!

[nicrnicr]

Thank you GreyGeek for your advice, but
- I think that there are bugs at the begining in Kubuntu 18.04 on the contrary to an old software like Kubuntu 16.04.
- I don't understand why, but the people who create Kubuntu change the name of the applications. For instance Ksnapshot in Kubuntu 14.04 became Spectacle in Kubuntu 16.04. I don't need and I don't want to learn new names.
- I would have to update a few times this system. I think that each time you update a computer, it gets slower and some applications might no longer work.
- I see very little difference between Kubuntu 14.04 and Kubuntu 16.04 (More precisely I find Kubuntu 14.04 better because there is the software manager muon). Therefore I don't see the point in installing the latest version of Kubuntu, because I guess that the differences with Kubuntu 16.04 are negligeable for me.
- I will still have later the possibility the install Kubuntu 18.04 or later on an onther part of my HDD.

I have

kubuntu@kubuntu:~$ sudo parted /dev/sda 'print'

Disk /dev/sda: 500GB

Now I try to install Kubuntu 16.04 again.

[nicrnicr]

Thank you GreyGeek for having given me an advice but:
The screen showed me that "It was not possible to do "grub install /dev/sda2". It is is a big failure".

Thank you GreyGeek for your advice, but
- I think that there are bugs at the begining in Kubuntu 18.04 on the contrary to an old software like Kubuntu 16.04.

There are bugs in all software, but I doubt that bugs in 18.04's installation procedures are giving you the problems you claim.

- I don't understand why, but the people who create Kubuntu change the name of the applications. For instance Ksnapshot in Kubuntu 14.04 became Spectacle in Kubuntu 16.04. I don't need and I don't want to learn new names.

Sorry, but the folks who do the programming call the shots, because most are doing it without pay while using their own equipment and time. Most also have a life, family and friends. If you don't want to keep up with the changes there's nothing anyone here on KFN can do to help you. I'm 76, and have my own memory problems, but I am very appreciative of the work the Kubuntu & KDE Neon developers and helpers do creating the finest OS & apps in the world!

- I would have to update a few times this system. I think that each time you update a computer, it gets slower and some applications might no longer work.

Mine doesn't. In fact, my most recent update of NVidia from 378 to 390 has almost doubled my frame rate. The average speed of your system depends a LOT on what additional services you activate or add. The more processes running in background in memory the less time the CPU has for doing what you ask it.
That will especially be true IF you run a release past its EOL and it gets infected and hijacks your computer. You'll notice a speed slowdown on both your system and your network, HD space will get eaten up, and, perhaps, someday, you might get a knock on the door from your local law enforcement demanding your computer because they traced child porn to your IP. All because you wanted to stay with an EOL release.

- I see very little difference between Kubuntu 14.04 and Kubuntu 16.04 (More precisely I find Kubuntu 14.04 better because there is the software manager muon). Therefore I don't see the point in installing the latest version of Kubuntu, because I guess that the differences with Kubuntu 16.04 are negligeable for me.

Then don't upgrade or change. When the EOL is reached do you think you are qualified to do your own support, to patch apps, libraries and security holes that won't be patched by the update system because your 14.04 is at its End Of Life?

- I will still have later the possibility the install Kubuntu 18.04 or later on an onther part of my HDD.

That's very true. But the only thing that will have not changed is YOUR abilities, if you don't want to make progress in improving them, so I suspect that your success rate then will be little different than it is now.

[nicrnicr]

Ok GreyGeek, you convinced me. In deed I have to keep on being updated if I don't want to reach my EOL too soon...

Dear GreyGeek,
Thank you very much for all the time you spent with my problem.
I have the same problem with Kubuntu 18.04:
- At the begining of the installation, as I choose the keyboard, the screen showed: "ubi-console-setup crashed". "ubi-console-setup failed with exit code 1. Further information may be found in /var/log/syslog/. Do you want to try running this step again before continuing? If you do not, your installation may fail entirely or may be broken.".
I clicked on "try again", but than I received the same message.
- Therefore I installed Kubuntu 18.04 again on the USB drive.
For the second installation I got that it is impossible to do "grub install /dev/sda". This is a big failure".
For the third one I got that it is impossible to do "grub install /dev/sda2". This is a big failure".

[GreyGeek]

What to do ...
First, considering all the things you’ve done, or did and didn’t report, with everything your doing resulting in failure, I suggest that you do the following:
1. Delete all the partitions in the 4th primary partition, so that the only partitions left are your three Windows partitions and an empty raw 4th primary partition.
2 Reboot to make sure you can still boot into Windows. If you can, fine. If you can’t even boot into Window then boot a boot-repair USB stick and fix it.

3. With Windows booting and running OK you are now faced with three choices:
A- Run Windows and forgetting about installing Linux
B- Retry installing Kubuntu on the 4th primary partition. That involves downloading a fresh copy of the ISO AND MAKING SURE the checksum is valid for both the ISO and the USB. Booting the USB and installing Kubuntu without trying anything fancy that would lead to another failure
C- Do step B but instead of installing on the fourth partition let it install to the ENTIRE hard disk, overwriting Windows and all other partitions, making Bionic the sole OS on your HD.

My recommendation: Option A

[woodsmoke]

I personally
in over a decade of this have

NEVER

seen this message:

- At the begining of the installation,
as I choose the keyboard, t
he screen showed: "ubi-console-setup crashed". "ubi-console-setup failed with exit code 1.
Further information may be found in /var/log/syslog/.
Do you want to try running this step again before continuing?
If you do not, your installation may fail entirely or may be broken.".
