Yes you can dual boot the x86 and x64 versions of Windows XP.

Hi, is it possible having winxp 32 and 64 on the same hd or system have to
be only x32 or x64 with no possible dual boot?

I triple boot XP Home, 64-bit XP Pro beta, and 64-bit Linux, so yes it is
possible for 64-bit XP to coexists with other OS's (and it runs 32-bit
Windows apps fine). XP64 included a 2D video driver for my video, and I
found an unsigned 64-bit nVidia 3D driver. It had no driver for my sound,
but I found an unsigned 64-bit AC'97 sound driver on realtek.com.tw. I
have not found a 64-bit driver for my controllerless modem (Windmodem),
but I have adsl anyway. The 64-bit XP Pro beta version I have expires 360
days from installation, but its partition can be read by other Windows
XP/2k versions.

CAUTION: Make sure you back up anything essential before installing 64-bit
XP. You may be safe if your partition table geometry is already
translated to 255 heads, but mine was 240 heads and 64-bit XP changed it
to 255 heads (which also changed cylinders), so 64-bit XP could not reboot
itself or XP Home until I repaired the partition table (recreated it with
240 heads and matching cylinders).

Note that I did not have Linux installed at that time. But Linux also
ignored existing partition table geometry and wanted to change it from 240
heads to 255 heads. But I recognized it, and prevented it from being
changed again.

So I am just curious if 64-bit XP Pro and some recent Linux versions use
the same openly available disk partitioning software, or just coincidence
that they both made the "incorrect" assumption that a large drive would
already be configured for 255 heads?
 
How did you reconfig you hard drive to 240 and how did you recognize it was
doing so. I have built my first machine with AMD Athlon 64 3400 on a epox
8KDA3I mother board. So in part I am just begining. Thanks for your Posts.
