After a power failure, it became impossible to boot. fsck found several problems on the / partition and I tried many things to repear, without success. So, I decided to reinstall, but the system hangs while launching gparted (I want to keep my /home partition and a Windows one).
I remember that I had already some difficulties about that when I installed the first time. I was obliged to use another CD to create my partitions and after that all was Ok.
How can I do now to reinstall keeping my partitions and reformating only / ?
