Ubuntu installation failure - Vaio Nvidia and RAID connected to the problem

[Gui Badoux]

At first, impossible to install Lubuntu 15 on a Sony Vaio PCG-31111M.
By suppressing the RAID0 of 4 SSD 64Gb, I could install on the disk0. But still very unstable system.
Then by acting on the TPM in the BIOS, a first installation was done. The TPM actions where first a CLEAR, then a ENABLED.
In the internet comments, some people were speaking about the Nvidia processor. So I installed the Nvidia pilot (a Nvidia native pilot, but approved by Ubuntu) and finally, a first installation of Lubuntu 15 was done.
But It's impossible to install something better, like Ubuntu 20 for example. The installation keeps crashing at the end.
For unknown raisons, the wifi pilot was lost, and impossible to restore it.

What is "Lubuntu 15"? This is not a version number used by Ubuntu or any of its flavors.

What is an "Nvidia pilot"? Do you mean an Nvidia driver? The Nvidia drivers supported on Ubuntu are the packages which are provided through the Ubuntu repository.

What exactly do you see when the Ubuntu 20.04 installer crashes? The installer logs attached to your bug report don't appear to show any crashes.

Hi Steve,
The version is Lubuntu 15.4. When I tried to upgrade this OS, a message appeared saying "to old for upgrade. Install the version 15.10". So I will download Lubuntu 15.10 and give a try.
"Nvidia pilot" means "Nvidia driver", yes indeed.
I took some pictures of the error messages appearing during the installation.
The only working installation was the Lubuntu 15.4. To get there, I erased the four SSD disks (after removing the RAID0 from the BIOS). Then I formatted the SSD disk0 with the option "bootable" activated.
Each other installation (like the Ubuntu 20.04) done on top of this first installation failed. I tried the two options: "install aside of the previous OS" and "Replace previous OS".

This is another error message

Problem solved!
Apparently the problem came from Windows OS: impossible to fully replace Windows by Ubuntu.
So I decided to go for a dual boot. I reinstalled Windows 7 on the Vaio. Then I installed Ubuntu as a second OS. I resized the disk so as to attribute a minimum of space to Windows (60Gb) and a maximum (190Gb) to Ubuntu.

Thanks for your comments in #5:
> Apparently the problem came from Windows OS:
So not an Ubuntu issue.
