Hi Paul, that is corrects, /dev/sda1 is /boot and /dev/sda2 is /.
I know that both are ext3, actually in my /etc/fstab it shows that both are mounted as ext3. However with the rescue disk it, it tells me that /boot is fine but that /dev/sda2 is ext2 with issues. I was wondering, is using the rescue disk from FC4 or FC6 a good idea to run fsck with and try to fix sda2? thanks (also for the link!!) Ron Paul M.
