Hi, Davien.
Sure. As the others said, many of us have been dual-booting the two
versions of WinXP since x64 first became available.
And you sure don't need 2 HDs. What you need in any Windows dual-boot
system is multiple VOLUMES. We often say "drives" or "partitions", but
those terms are not quite correct. A volume can be a primary partition or
it can be a logical drive in an extended partition - on any HD in your
computer. Windows doesn't care how many HDs or how many volumes you have,
so long as you put each Windows installation into a separate volume.
Just remember the Golden Rule of dual-booting: always install the newest
version of Windows LAST. Each version of WinNT4/2K/XP/2K3 includes the 3
"system files" NTLDR, NTDETECT.com and Boot.ini, but each version of those
NT* files is bigger than the one before. That's because each one knows how
to handle earlier versions of Windows, but can't know about whatever
versions may come later. Those 3 system files must always go into the
Active (bootable) primary partition on the HD designated in the BIOS as the
current boot device. This partition (typically C:, but not always) becomes
the "System Partition". Each reboot starts in this partition with these
three files, then branches to whichever volume holds the \Windows folder for
the Windows version you choose from the opening menu. So, even if you
decide to install WinXP x64 into E:, for example, the boot will start in C:
and then branch to E:\Windows to load WinXP x64. If you later decide not to
keep x64, just reformat E: - or delete E:\Windows - and also delete from
C:\boot.ini the line under [operating systems] that points to that option.
It sounds like you've been dual-booting other Windows versions, so you
probably already know all this, but...just in case. ;<)
