Hate to say this, but you are *not* correct. Most OEM computers that
come with a preinstalled copy of Windows have that copy BIOS-locked to
the motherboard, as unclegrumpy said. If you change motherboards, the
copy of Windows will no longer install.
If you were able to do this, then either you don't have an
preinstalled OEM version, or yours is from an OEM that doesn't use a
BIOS-locked version.
Let's bring this back to the OP's situation:
<quote>
I have an HP system with a hidden recovery partition on it. I purchased
and
built a new system from scratch, and I want to transfer my copy of XP
onto
it. I plan on installing a version of Linux on my old system which
currently
has XP on it. I understand that I can use any XP installation disk to
install on the new system, and that I can use my key (which is legit and
I
own it). I don't have a disk to use, however. Does anyone know how I
can
create an installation disk?

If, for whatever reason, OP had a *retail* version of XP installed on
his HP (which I'm sure he doesn't; he surely has an HP BIOS-locked OEM
version), then he could install Linux on the HP and install XP on the
new machine he built. But if it is indeed an HP OEM version of XP, then
the license states that it cannot be transferred to another computer.
If the hard drive on the HP were erased for whatever reason, then OP
could obtain (borrow) a generic OEM XP installation disc and do a clean
install using his HP product key. But suppose he were to try to use this
same generic OEM disc and wanted to install XP on the new machine?
Legally, he needs a license, of course. But if he tried it anyway, is it
right to assume that the product key shouldn't work since it is
associated with HP? What is actually BIOS-locked: a particular file or
set of files on the HP OEM installation disk? The product key? Both?
And what's with the Subject: old by any of?
