Are you certain your boot disk is hd0,0? Could it be that hd0 is actually the extended partition, and hd0,1 - hd0,8 are the logical partitions.
Use a boot disk, LiveCD, then mount each partition under the LiveCD, then you should be able to determine which part is actually your boot part.

Once you boot up the system with a LiveCD, you can then mount your filesystem, then chroot to your filesystem, fix your boot loader.

FDISK(8)						      System Manager's Manual							  FDISK(8)

NAME
fdisk - partition a hard disk [IBM] SYNOPSIS
fdisk [-hm] [-sn] [file] OPTIONS
-h Number of disk heads is m -s Number of sectors per track is n EXAMPLES
fdisk /dev/hd0 # Examine disk partitions fdisk -h9 /dev/hd0 # Examine disk with 9 heads DESCRIPTION
When fdisk starts up, it reads in the partition table and displays it. It then presents a menu to allow the user to modify partitions, store the partition table on a file, or load it from a file. Partitions can be marked as MINIX, DOS or other, as well as active or not. Using fdisk is self-explanatory. However, be aware that repartitioning a disk will cause information on it to be lost. Rebooting the sys- tem immediately is mandatory after changing partition sizes and parameters. MINIX, XENIX, PC-IX, and MS-DOS all have different partition numbering schemes. Thus when using multiple systems on the same disk, be careful. Note that MINIX, unlike MS-DOS , cannot access the last sector in a partition with an odd number of sectors. The reason that odd partition sizes do not cause a problem with MS-DOS is that MS-DOS allocates disk space in units of 512-byte sectors, whereas MINIX uses 1K blocks. Fdisk has a variety of other features that can be seen by typing h. Fdisk normally knows the geometry of the device by asking the driver. You can use the -h and -s options to override the numbers found. SEE ALSO
