Install 32 bit Version of XP Pro after x64

I upgrade my computers (2) ever 3 years or so. Last year I upgraded to dual
core ... and had xp pro x64 installed. This works good for me. However my
wife is having dificulty with some websites. I am going to try uninstalling
the NVida firewall and see if that works for her. I did buy two full copies
of the 32 bit XP Pro to install on both computers. My thoughts are that I
install a new HD and disconect the x 64 drive. Install the 32 bit o/s on the
new drive. Set the new drive as a slave, and reinstall the x64 drive. Now
from there how do I get the dual boot to work?

btw I am a not an IT professional, just a hobbiest.

I read post "How to restore dual boot of xp 32 and win 64". Will this work in
this case?

You can tranfer files and settings only. Apps have to be reinstalled.

If it concerns the location of the boot files, probably - yes. If it was
authored by John Barnes - most assuredly!

As I have it, your BIOS has more clout than the 'master'/'slave' connection.

You want 1 MBR on the system to handle both OS's - ordinarily you install
the oldest first, but in your situation, I think you can do it one way or
the other, but you have to put the boot files from the 32bit OS onto the
system drive - or, if you change system drives, put the boot files from the
64bit OS onto what will then become the new system drive?

Thanks,

As I understand it the 64 bit o/s boot files are backward compatible with the
the 32 bit o/s. So... If my system drive has the 64 bit boot files and I boot
to the 32 bit o/s it should work. Or am I way off here.

That may depend what you mean, but as seen from the booting sub-system they
should be compatible, they just have to all be on the system drive so that
the system can see them and arrange for a boot-menu that you can choose
from. This means the compatibility happens before any OS has booted, the
BIOS is still in command.

The BIOS programs generally don't have to be very intelligent - they must be
small, fast and to-the-point, so install several OS's in parallel, and you
could easily confuse the BIOS about the number of systems and which one is
it that you like to boot at any given time? (It doesn't read your mind very
well!) You may have to do some tricks - like editing, to have the combined
knowledge in place in order that the BIOS can see what is going on, and the
different systems do not confuse each other. This inconvenience, the
installer takes care of for you, if you install in the recommended order -
oldest first.

If you are in a NewsReader like OE-e (much recommended) you can search for
contributions of the real experts here: 'Darrell Gorter', 'John Barnes'
and 'Charlie Russel' (just to name a few) what the rest of us know about
this issue, we more-or-less picked up from them.

Don't forget that you must first install the nVidia firewall if you passed
that step when first installing. Then remove from Add/Remove programs.

I would not change the Master/Slave order of the drives. If the current
drive is Master, install the new drive as slave.

With the Master out of the system (unplug the power), most BIOS's will
automatically set the slave as first HDD in boot priority. If not, you may
need to set this. Install your new system on the slave. Replug the master.
Reset boot priority to have the master the first HDD.

Easiest way from there, you should boot into x64. Go into System
Properties, Advanced / Startup and edit your boot.ini from there.
Duplicate the entry under (operating systems) change your description and
change rdisk to 1
Save the boot.ini and then you can change the timeout and default os to your
desires.

This assumes that both drives have 1 partition each. Also if you are
uncomfortable editing the boot.ini, make a copy of it first. You can always
change boot priority and boot into the other system to fix it if necessary.
Good luck.

I am puzzled. Why don't you simply install the new drive as slave, then
use the Disk Manager of the present installation to set up the new
drive. Next, install XP Pro 32 with the old drive connected. That way
the installer will set up the dual boot for you.

Usually, one would try to install the OSs in order of release; however,
I believe the 64 and 32 bit versions of XP use the same boot loader.
Now, mix in Windows 9x, older NT up to Windows 2000 or Longhorn/Vista
and, the situation changes.

There are only two reasons I can think of for disconnecting the original
HS before the install of XP Pro 32: 1) you have fear that somehow the
installation procedure for the 2nd OS will corrupt the first; 2) you
want to use something other than the XP boot manager.

That aside, nothing wrong with what you outline but why complicate
matters? Is there something I have overlooked in all of this?

Win XP Pro 32-bit cannot set up a dual boot with Win x64
already installed because it cannot recognize the newer
operating system. If Win XP Pro 32-bit is already installed
(the older OS) and you then install Win x64 (the newer OS)
on a separate drive or partition, Win x64 does recognize the
older OS and configures the Boot.Ini for dual booting.

Thank you for your reply. This reply reflects the usual advice on the
topic, contains only assertion; it is well-intentioned and well-founded
assertion but assertion nonetheless; and is only partly correct.

I suspect you have not actually tried to do what you claim is not
possible _with _ _Windows_ _XP64_ _and_ _Windows_ _XP32_. If you had,
you would have discovered that you can install Windows pro 64 and then,
when that installation is complete or at some future time, install
Windows XP Pro 32 bit. As part of that procedure, one must select a
drive (real or logical) that does not contain another operating system.
When you have finished the installation of the 32 bit system, you will
have a dual booting system using the Windows XP boot manager.

I have done it more than once.

To forestall misunderstanding, I repeat that this is an exception to the
usual best-practice recommendation of installing OSs in order of
release.

Sorry Tom, but when you install XP86 after X64 with X64 still visible to
allow dual booting, the ntldr and ntdetect.com files are overwritten and the
ntldr file from the X86 install does not recognize X64 and therefore you
cannot boot into X64.

How foolish of me to believe the evidence of my own eyes.

So, when I took some time yesterday to:

1) delete every partition from the three drives of one of my computers;
2) used Acronis Disk Director to create one primary partition on each
drive;
3) installed Windows XP 64 bit with disk 1 as system (startup/boot
files) and 2 as boot volume (OS files);
4) installed Windows XP 32 bit with disk 3 as boot volume and 1 still as
system;

and ended up with a dual-booting system using the Windows XP boot
loader, I was actually living in a not-so-parallel universe where the
"usual rules", those you and others have stated, did not apply.

As I have written twice before-it does work. I have done it.

Is it that you simply do not believe me?

I suggest you try it.

I guess you're just really lucky. While the Beta was
available and after RTM, there were many who tried
installing x64 first and then x86 who ended up without the
capability to dual boot initially. Charlie Russel posted a
web page about dual booting that includes information on
order of installation.

And I did try it, but it didn't work your way!

Not to doubt your success, let's speculate why you are able to do so and
most are not.

Perhaps Microsoft started including the newer version of ntldr on X86 disks
at some point after the release of X64. Those with older versions of XP
won't work. Mine version of XP86 was released in December of 2004 with SP2
included and version of ntldr is dated Wednesday, â??August â??04, â??2004,
â??â??4:00:00 AM.

What is the date on the ntldr file on your XP86 in the I386 folder?

The other possibility is Microsoft in later versions included a date check
in the install program that would bypass rewriting the ntldr file if the one
present is a later version. This I would assume unlikely, but possible.

If it does it, perhaps he also used Acronis to create a partition manager.

Except that he has XP dual boot when done. If he used Acronis to make the
older ntldr install on another than the system drive, the boot.ini on the
system drive wouldn't be updated with both systems.

I have read the subsequent replies from Theo, John, Colin, and John
(second reply). Here I add some information that might be useful in
understanding what is and is not happening.

Windows XP 32 bit is SP 2, Windows XP 64 bit is SP1. So, as I am
confident you all know, both are at the same "patch level" despite the
different SP designation.

After installation of XP 64 bit, ntdetect.com and ntldr are dated
3/25/2005. After installing XP Pro 32 bit, the dates are the same.

Not only do both systems appear on the XP boot menu, each will boot
properly when selected. If you later install Vista (either 32 or 64 bit
or one after the other), Vista will set up its boot loader with a
reference to earlier OSs. Selecting that during boot will cause the
Vista boot loader to pass control to the XP loader just as happens if
you set it all up installing strictly in the order of issue.
