Dual Booting Windows XP 32 and 64
 

I have a machine with XP Pro 32 bit installed. I bought a new hard
drive and installed XP64 on it. I unplugged the drive with XP 32 bit on
it during the installation. Now when I boot up, I don't get the choice
of which OS to start up in.

What do I need to do to get the option?

Thanks in advance for any help,
Jeremy

Make sure that your system drive %systemroot% has the x64 ntldr NTDETECT.com
and boot.ini on it
You can probably solve this by making the drive with x64 on it the first HD
in your boot order.

The drive with 64bit installed on it isn't one of the choices... *sigh*
Why can't this ever be easy?

Any other ideas?

Thanks,
Jeremy

Also, since you only had the one drive when you installed x64, you will need
to add the other system to your boot.ini either from System Properties or
using the Recovery Console

Then, boot to x86, copy the files from the x64 install to the x86 drive
after moving the old files into a new folder to save them. Fix the boot.ini
to show the two systems as recommended above. System Properties or Recovery
Console (easiest if you aren't comfortable with modifying the boot.ini with
notepad)

1. What's the syntax to combine the boot.ini file?
2. Once I combine the 2, do I use it as the .ini file for both driveS?

Here is what is in my 32 bit file:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP
Professional" /fastdetect /NoExecute=AlwaysOff

Here is what's in the 64 bit file:
[boot loader]
timeout=1
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windo ws XP Professional
x64 Edition" /noexecute=optin /fastdetect

Thanks again,
Jeremy

You have two options:

1) Install WXP x86 then WXP x64 as other poster already suggested.
2) Get hard a disk utility such as Partition Magic 8, create a new
primary partition, and install WXP x64 there.
If you opted for 2), switching between WXP x86 and WXP x64 can be done
using "PQBoot for Windows" , utility which comes with Partition Magic.

The following will fix the problem:

Note that assumption here is that WXP x86 is installed in the Primary
Master HD and WXP x64 is in the Primary Slave HD.

1) Boot to WXP x86(32Bit) and replace ntldr and NTDETECT.COM with those
in WXP x64 CDROM.

2) Modify boot.ini as follows:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP
Professional" /fastdetect /NoExecute=AlwaysOff
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Windo ws XP Professional
x64 Edition" /noexecute=optin /fastdetect

Don't worry - you did it right - I always unplug the drive
with the first OS on it before installing the second - this way
both run installed "on and as" C:\
Just fix the boot.ini like "honjo" says and if that doesn't work
you will have to do a bit of research based on how your drives
are connected.
You'll have to learn what all this gobble - d - goop actually means.
multi(0)disk(0)rdisk(0)partition(1)\

Actually, it would have been "easy" -- entirely automatic, in fact --
if you hadn't disconnected the other hard drive before installing WinXPx64.
