    Yesterday I started to notice a failing hard drive on my freebsd server.

    In my haste to back up the existing hard drive to a new hard drive, I
    forgot to make sure that the partitions match on the new hard drive (ie, /
    on the original hard drive was /dev/ad0s1a, the new root partition is on
    /ad0s1e).

    Once I realized my mistake, I was about to mount the new hard drive
    manually using the emergency fix shell from the FreeBSD cd. So, I mounted
    the new partition and edited the new /etc/fstab file, and recreated the
    devices (just to be sure) in /dev.

    However, now whenever I boot, I get the following:

    Invalid partition
    No /boot/loader

    >>FreeBSD/i386 BOOT
    Default: 0:ad(0,a)/kernel
    boot:

    At the "boot:" prompt if I enter "0:ad(0,e)/kernel", it boots fine.

    Apparently I just need to rewrite the new boot block information. I've
    gone through the /stand/sysinstall "fdisk" and "Label" menu options and
    rewritten the new layouts to the drive, but no dice.

    Does anyone know of a way to fix this ? It's not a big deal, I'd just
    like the machine to boot automatically without having to have someone
    enter the new boot path every time.

    Thanks in advance,

    James Schmidt
