PartitionMagic prevents boot

What I did:

I accidently hid the default boot partition of my hard drive with PartitionMagic.

 

Message during boot:

"Current operation (1 of 1)

Hiding partition: C: (NTFS, Primary volume, 238464.8 MB on disk: 2)

Entire Progress: 99%

Error 4. Bad argument/parameter

Entire progress 100%

Errror 4 while executing batch.

Error 4. Bad argument/parameter

Will now reboot.

Press any key to continue"

 

Result:

System can't boot hard drive and looks for floppy.

 

What I did next:

I boot a DOS6.22 floppy and run FDISK.  It says:

"Warning! No partitions are set active - disk 1 is not startable unless a partition is set active"

Flashing: "Unable to access drive 2."

 

So I set disk 1 partition 1 to Active.

 

Result:

Now the bootup fails after the Windows XP banner with:

"XMNT2002 Program not found -- Skipping autocheck"

"Autocheck program not found -- skipping autocheck".

That's probably normal if the partition is still hidden and those programs are in that hidden partition!

 

What I do next:

I boot the PartitionMagic rescue disks.  PartitionMagic runs and finds some errors in partion lengths. I OK the error fixes and unhide the boot partition and set it Active again.  Then I reboot -- but the text from the batch file looks just like the original, setting the partition to hidden again!  Did the previous "Error 4" errors cause the original batch to be saved and run again each time I boot?

 

Result:

System can't boot hard drive and looks for floppy.

So I again boot DOS6.22 and set the partition Active.

 

Result:

The bootup always fails after the Windows XP banner with:

"XMNT2002 Program not found -- Skipping autocheck"

"Autocheck program not found -- skipping autocheck"

and then automatically reboots.

 

Question:

How am I going to make this computer boot again?
