After a migration of my home server to a new mirrored 500GB sata setup from my old 160GB pata system, I encountered some problems with booting the server. Intially booting stopped at:
This was fixed by booting from the FC6 DVD and selecting "linux rescue". I then chrooted to my install with "chroot /mnt/sysimage", followed by a "grub-install".
This fixed my first problem but now boot was hanging at:
GRUB loading stage 2
So again, back into the rescue boot and my chroot environment. Now I ran "/sbin/grub" which took me into the grub shell. I ran "root (hd0,0)" to use the first partition of the boot disk, then ran "setup (hd0).
Next boot all was well.
