A co-worker swapped SCSI RAID controllers on our system running RHEL 3.0 and lost the partition table of our boot disk. He was able to recover it (apparently) using gpart but the system will not boot. I can boot into rescue mode using a cd and mount all partitions and they all appear to be ok. Fsck marks them all as ok. I have run grub to be sure /boot was ok and grub-install /dev/sda to rebuild the MBR but we still get: No Operating System found when we try to boot the system. Isn't grub-install supposed to rebuild the MBR? Do I need (dare) to run fdisk /mbr? Any ideas will be gratefully appreciated.
