So, now, your grub.conf should have something like this: title Fedora Core (2.6.12-1.1372_FC3) root (hd0,1) kernel /vmlinuz-2.6.12-1.1372_FC3 ro root=/dev/hda3 rhgb quiet initrd /initrd-2.6.12-1.1372_FC3.img As explained in another email, the root line refers to the, usually, separate /boot partition and starts counting from 0, so /dev/hda2 is equivalent to (hd0,1).... Then on the kernel line you can either use labels or actual device names, I prefer to use device names, so we simply directly specify the /dev/hda3 there. Of course, I am assuming that /dev/hda3 is in fact your "/" partition. I suppose the other possibility is that the "/" partition is inside the LVM on /dev/hda5, but then we would need to specify the "LVM" device name, not the raw /dev/hda5 name.... You said you were receiving a kernel panic. Can you post the grub.conf line that at least gets you to a kernel panic and then a rough transcription of the errors just before the panic? --Rob
