I understand this now.  Unfortunately I didn't
understand it at the time.  :(

After seeing the three or four responses to my
question, I now believe that the line above is
probably not responsible for what has happened.  I'm
inclined to believe that this line didn't really do
anything (or created some other problem I'll find out
about later).  :|

I think I must have copied /boot/boot0 from the FBSD
CD into the C:\ directory on XP (from inside XP), and
then renamed it C:\bootsect.bsd.

Then when the option came up on the NT loader's dual
boot menu, I selected it.  If I understand this
correctly (and if I'm making an accurate assessment of
the situation), the boot/boot0 (which is the null
value one from the FBSD CD -- NOT the one from my
primary slave FBSD drive) had nowhere to go, and just
sends me to the default screen:

 F5        1
 Default   F5

...where I can't hit any key without getting beeps and
nothing happening.  This, then, re-sets the default
boot information to itself which creates the endless
loops, so that rebooting just goes the same place, and
Microsoft OS and/or recovery tools can't even see the
contents of the disk, rendering any sort of repairs
apparently inoperable, at least from DOS or XP.

Thanks to Luke's suggestion, I'm currently attempting
to load Linux over FBSD to then attempt to mount the
NTFS drive, which may allow me to see the contents of
that drive, to either copy them elsewhere to salvage
the data, or to determine whether restoring it is

If you (or anyone on the list) have additional
suggestions or ideas in light of this new scenario,
please let me know urgently.  Thanks!!!

How can I do this when I can't read or get into the
disk?  Maybe someone has a boot floppy from which I
can do this, you can email me?  Or do I need to hook
it up to a different machine with Norton loaded on it?
