Hi, JP.
HOW did you install x64 onto D:?
What you describe should have worked the first time...IF you simply booted
from the WinXP x64 CD-ROM and let it update the startup files on C: as it
installed x64 on D: (or wherever). When it finished, C:\NTLDR and
C:\NTDETECT.COM would have been the x64 versions, as John Barnes said. And
C:\boot.ini would automatically have been updated to point to both the x86
and the x64 versions of WinXP.
But, if you used a third-party boot manager, it might have handled the x64
installation differently. Or, if you changed the boot device in CMOS to the
other HD, then the x64 installation would have written its startup files
onto that HD, rather than to C:. And there are other installation methods
that might have frustrated WinXP x64's attempt to keep it simple. :>(
When using WinXP's default method of dual-booting, there's only a single
System Partition (typically C:) for the whole computer, but a separate Boot
Volume (one of which may or may not also be C:) for each Windows
installation. Each boot starts in C:, then branches to wherever C:\boot.ini
points to load your chosen installation.
What steps did you use to install WinXP x64? How many versions of NTLDR do
you have? How many boot.ini files do you have? Where are they? What do
they say?
