PS. If I install ontop of OS3.5 its ok,but that means 3.1>3.5>3.9
Why do you have 3.1 in this list ? The correct way is empty hdd -> 3.9 or empty hdd -> 3.5 -> 3.9 if you insist on upgrading.
Both 3.5 and 3.9 allow you to create a boot disk (a.k.a. emergency disk). Once you have created such, you can through away your 3.1 disks. In 3.9 it's even the first step of the installation and it says "do this first" (at least the german translation does). Why did you skip it ?
If you really don't want to boot from a 3.9 disk and insist on using your old and dated 3.1 disks, including a painful lot of disk changes during installation, you can install 3.9, reboot and install 3.9 again. Then the icons are ok.
