I actually succeeded in performing the installation, with the media I had.
I already check the integrity of the iso I downloaded and it was OK.
The onlly thing I changed in the way of installing is that I used gparted prior to launching the installation to erase all partition I could have on my disk. (booting on the Live CD)
Then the installation occured without any issue.

What may caused the problem is that the 1st partition was actually a "backup" one, used by the manufacturer
