Justin, Any idea why anaconda in FC4 can't find my boot partition to upgrade? Also do the commands... grub install --stage2=/boot/grub/stage2 (hd0,0)/grub/stage1 (hd0) \ (hd0,0)/grub/stage2 p (hd0,0)/grub/grub.conf install --stage2=/boot/grub/stage2 (hd1,0)/grub/stage1 (hd1) \ (hd1,0)/grub/stage2 p (hd1,0)/grub/grub.conf look correct to you? I guess I could at least try reinstalling my grub partitions. Before I used... boot device (hd0) /dev/sdb root (hd0,0) setup (hd0) device (hd0) /dev/sda root (hd0,0) setup (hd0) ...previously to install grub on both drives which have the RAID-1 boot partition. It would be nice if there was a consensus on the proper way to install a RAID-1 boot partition....to use... root (hd0,0) in grub.conf and the second set of grub commands with only (hd0,0) or to omit the 'root (hd0,0)' from grub.conf and use the commands Aleksandar recommends. Of course none of this explains yet why anaconda can't find the boot partition to update. Jack
