It is my experience that the error message is often not
exactly what the problem is. That is, the OS is confused
by not finding the right files or data in expected place
and spewing its wild guess. Most likely, it is a result
of looking at the wrong partition for the file.

I am still very curious whether or not your target volume
can be successfully booted from the floppy disk option.
It will give us some clue as to whether the problem is
confined to the initial steps or not. That is, if the
target volume can be booted, it proves that the problem is
one of the following areas:

1. MBR's boot code
2. Boot sector's program
3. NTLDR
4. BOOT.INI

since all of these are supplied by the diskette, we
can positively say the problem is one of this. It is
my hunch that this is the case.

To determine the real culprit of this problem, I would
like you to run the following command:

XXCLONE /DIAG

this procedure will create a hex dump file, C:\XXCLONE.DAT
which shows the contents of the key sectors (MBR, bootsectors).

Please run this command when your target disk is bootable
(after you run the recovery console - fixboot) and also
after you make the XXCLONE operation (which makes it
unbootable). Please send the two files (make sure that
you rename the XXCLONE.DAT file after the first run
because the second run will overwrite the first one.
Please send the files to me for our examination.
