I reinstalled a functioning hd + o/s to the origonal pc, but get above error.(I had planed to use it on another pc, but did'nt in the end.)
Booting from Win2K floppy recovery disks to Consol, then repair shows an undefined error,unable to repair.
Map the drive shows;
?             0Mb         \Device\HardDisk0\Partition0
C:NTFS   12974Mb  \Device\HardDisk0\Partition1
Using Delete shows ony C: etc, not '?'
Boot.ini shows;
Default= multi(0)Disk(0)Rdisk(0)Partition(1)\Winnt
I have Partition Magic7 on another pc so used the recovery floppies to boot into PM7, this shows only the single partition.
Am not sure how to overcome, other than Format

I don't really understand how that 0Mb partition got there, but I suggest you delete that partition using Fdisk and set the 12974 one to active, now edit the boot.ini to Default= multi(0)Disk(0)Rdisk(0)Partition(0)\Winnt

Don't know why partition 0 of 0MB is there.  But that's what your partition table in the MBR shows.  You can try to trick the OS before deleting and possibly kill it all together.  Do the following:

1) Check your BIOS settings for the drive geometry (CHS or LBA).
2a If you need to change drive geometry - change it and reboot.
2b If you don't need to change the drive geometry then:
3  Edit and change the Boot.ini to point to the next partition Partition(0) to Partition(1)
4  Save and reboot - it should fix your problem and give you a better chance.

cheers

FDisk doesnt appear to be available from Consol.
DiskPart shows only C:
PM7 boot disks shows C: as active partion

Fdisk is available when you use a winME bootdisk wich you can get from http://www.bootdisk.com Be sure not to mess with the other partition as it will probably be NTFS formatted.

Then I suggest you edit boot.ini to:
Default= multi(0)Disk(0)Rdisk(0)Partition(0)\Winnt
and see if that works, you can't damage anything doing that.

If you have another harddisk near (at least 12974Mb big), and you can get your hands on Norton Ghost, you can also try this:
Create an image of your big partition on to that other hd (wich you can slave on that machine for this purpose)
Remove all partitions using Fdisk and create one big new one and set it to active. Don't format it.
Now put the image you created back to your drive. Boot.ini must be set to Default= multi(0)Disk(0)Rdisk(0)Partition(0)\Winnt then.

p.s. don't perform this if your harddisk is a dynamic disk.

The change to your boot.ini should be:

Default= multi(0)Disk(0)Rdisk(0)Partition(2)\Winnt

The partition should be TWO - it's not zero relative.....it's one relative.

Start | run | boot.ini | press the ENTER key, make the change and save.

cheers.....

Tried various changes to boot.ini without success.
Chkdsk shows unrepairable error
I'm afraid I decided to bite the bullit,and installed the o/s to the slave drive, as I could'nt afford any more time. Boots OK now off the slave. Have run various hd utilities on problem drive, which now reports no errors! - weird
Thanks for imput.
