XPx64 and XPx86 on same PC

Hi all

We have one PC at work with x64 on it, however due to lack of drivers our
IT man has put XP pro on it so it dual boots between x64 and x86, both
versions of XP have been installed into the same partition and from studying
this newsgroup I get the impression this could cause some problems. Can
someone confirm this? or is this a supported configuration ?

Last week I tried to boot into x64 and could not log in as the IT man has
not set up the Domain so re-booted into plain XP, now when trying to use
Internet explorer (which worked fine) I am told that the .exe file in
Program Files/Internet Explorer is not a Win32 application, can this have
been caused by the attempt to run x64 ?

Thanks for any help, as our IT man is currently not available.

Re: XPx64 and XPx86 on same PC

Operating systems should always be installed in separate partitions. The
older operating system should be installed first unless you know how to
configure the boot order.

x64 XP uses WINDOWS\system32 and Program Files for 64-bit files.
32-bit components are in WINDOWS\SysWOW64 and Program Files (x86).

32-bit XP uses WINDOWS\system32 and Program Files for 32-bit files, so if
both versions of XP are on the same partition there will be confusion.

Re: XPx64 and XPx86 on same PC

This is absolutely NOT a supported configuration. And a really bad idea. you
need to wipe that partition and start over. If you're going to dual boot,
use two partitions. Install 32-bit XP first, then install XP x64. See my
blog posts on multi-booting for details.

Re: XPx64 and XPx86 on same PC

Hi all

After further investigation it appears that the IT man has installed XP into
a folder other than the default so as not to overwrite the x64 installation.
I have passed on your advise and it looks like the current workaround is to
remove the dual boot option till he rebuilds the PC.

Thanks

Martin

Re: XPx64 and XPx86 on same PC

Even in a non-default folder it's a BAD IDEA. There are other folders
involved, and the view of the file system is different between 64-bit and
32-bit. The system needs a wipe and rebuild.

Re: XPx64 and XPx86 on same PC

I agree! Somewhere in the NT4 documentation, if I'm correct, this method was
listed as a (bad) option - I have never seen it mentioned again. Not
officially.

Do you have some documentation on what difference there should be?
 
Re: XPx64 and XPx86 on same PC

amongst other things, 32bit applications don't see the same
%windir%\system32 as 64 bit. And application installation directories are
different (32bit installs to "program files", 64bit does to - but installs
32bit apps to program files (x86) creating issues with 32bit and 64bit code
residing in the same putative directory.
