Need to restore XP boot files

[Michael]

I know that it is supposed to be done the other way around, but I installed
W2K after XP. Well, the XP was already on the machine. W2K loaded fine and
the OS select system displays and I can select W2K and it boots fine. If I
select XP it does not boot and there is an error message.

I know that this is because the XP boot files have been overwritten by the
W2K boot files. What I would be grateful for is advice on putting the XP
boot files back. What shall I put back - just ntldr? If I copy the ntldr
file from another XP machine and put that in the same place as the current
ntldr, will everything be just fine again? Or will I end up with a machine
that does not boot at all? Does it matter if the replacement ntldr file
comes from a machine without dual boot? I think no problem - only boot.ini
is controlling the dual boot - correct?

TIA

This article says ntldr and ntdetect.com files.

What I would do, to make sure, is to Boot the XP CD and, instead of
Setup, take the immediate R for Repair. Assume any password requested
is blank, and TAB over.

There use
COPY D:\i386\ntldr C:\ntldr
(The CD will almost certainly be seen as D
COPY D:\i386\ntdetect.com C:\ntdetect.com

which are the two boot-code files needed, and hope that they work with
the existing boot.ini. If there is further trouble, boot that way again
and use
ATTRIB -H -R -S C:\boot.ini
REN C:\boot.ini boot.2k
(so as to retain it)
BootCFG /Rebuild
