Hi! I have upgraded to Fedora Core 3 successfully after the fresh install which means deleted all old partition and reinstall. But when I choose "Language" and keyboard Language. A window which "BUG" title displayed with content "Assertion (heads > 0) at disk_dos.c : 485 in function probe_partition_for geom( ) failed" displayed and also displayed in partition making. Luckily, I can click "Cancel" three to four times then the installation continue. Also a LVM was installed after the installation finish but I remember that Fedora Core 2 didn't do that. Do the BUG window displayed is really a BUG ? Did the LVM is automatically installed in Fedora Core 3 by default ? Ringo
