After filing a new bug #973789, I came to the result, that the causes for my trouble (Precise install additionally to Lucid only through the alternate CD, now it runs only in rescue mode) is the graphics driver (I have a GeForce GT 240), for details see https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/973789
Maybe there is an additional problem, as my trial to install the proprietary NVidia driver, working in graphical rescue mode, failed.
Now I don't know how to continue: repeat the install from scratch according to Eduard's recommendations, or replace my actual driver by an appropriate one? But what is the actual driver, and which one to use now? nouveau is said to be not working on boot (#21), but it is recommended to install nouveau (#21), and the final target is apparently to end up with VESA (which I think is the driver in my rescue environment). Sorry for my beginner's kidding, but I have tried to install the xserver-xorg-video-nouveau driver by several ways.
For the time being I still work on Lucid, but I am eager to update to Precise.
