Hmm, it appears that your hard disk has no heads; that would be a problem : ). Sorry, couldn't resist. More likely, something is reporting that your hard disk has no heads, or returning a negative number to indicate an error. Your FC2 still works, I assume. Try doing an "fdisk -l" as root to see what it thinks your hard disk geometry is. Or do something similar with parted as that is what is used by the installer. > I did a google search and found some prior references to FC2 and FC3 test 2 > but nothing about the final release. Aha, there is a bug. It was marked as a duplicate of this bug: http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=138419 Looks like there are instructions there for a work-around. Jonathan
