I don't subscribe, so I can't post this response there. When I upgraded from FC2 to FC3, I saw the same error messages you saw about: "Assertion(heads>0) at disk_dos.c: 485 in function probe_partion_for_geom() failure." A web search found an explanation and a solution at: <http://lwn.net/Articles/86835> Apparently, the initial installation of FC2 damaged the disk geometry due to a bug in FC2. This interferes with upgrading to FC3. I applied the fix described in the LWN article and was able to upgrade successfully from FC2 to FC3. Hope this helps. -- ========================================================================= Bob Parnass, AJ9S GNU/Linux User http://parnass.com
