Hello everyone I will explain my story, as a premise I tell you that I am a novice person:
Today I wanted to install ubuntu on a secondary disk I had and to partition the disk I used fdisk.
The problem is that I made my various partitions on the main disk where I had installed Windows...
Searching the internet I was advised to use the testdisk tool to annualize the partitions.
I will put below the result of 'Analyze' (I am using it with a second Ubuntu partition I had on the secondary disk):

I tried selecting the ones I put in green (advice from ChatGPT), but when I go to the next screen I see it gives me this message

Can you please help me? (Please keep in mind in your answers that I have never used this tool before).

Please convert your shouting style capital letters in the title into netiquette-compliant small letters!

Use the most recent version of TestDisk instead of an outdated one.

As a TestDisk beginner you should cross-read

and read

Prepare a storage device (can as well be a USB pen drive) with some partitions whose content you can afford to loose.
Delete your partitions on that designated storage device and then try to recover those partitions using TestDisk.
The safest way is to use a separate computer where wrongdoing does not result in data loss.
Take your time.
This should make you familiar with TestDisk.

The next step would be to apply that method to your current case.
