Thank you to all people who answered.

It turns out that the first machine I picked over thirteen have a
problem either on the disk itself or on the disk controller. I have
successfully installed the others. I put the faulty computer apart for
the moment.

I will probably come back to this later and try to understand.

A live CD with gparted shows a LVM partition with a locker
symbol next to it. I tried to erase the first 512 sectors with dd
but it was not sufficient. Also I constantly get the message "F1 to
continue, F2 to BIOS" at every boot. I find it suspicious.
