The installer should offer to either install or upgrade your existing system, and if you choose upgrade at this point, it uprades the set of packages that you already have installed. If it says "do you want me to initialize the drive" - this is a bug - do _not_ initialize the drive! This would erase all information. Info at: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=236743 For the clean "-ish" install - remember your user account folder could contain incompatible settings, when you get to the installer screen above, choose install, then in the partitioning screen there is a drop-down with 4 options: - erase all and use full disk - erase linux partitions and use full disk - {forgotten} - custom You need to choose custom. On the disk layout screen, you select each of your partitions, edit, and set only the mount point to where you want the partition mounted {eg /home for the /home partition}. For LVM lv's you click edit, select the individual item, then edit again. To make the install "clean", set the partition that is for / to be formatted. Review your changes in the list at the bottom of the page, then double confirm the request to format {only} the / partition after you click next. DaveT.
