Re: vista Ultimate 32-bit to 64-bit
Time out.
Forget everything you ever knew about Vista x86 Setup. It does not apply to
Vista x64 Setup. They just don't work the same way. DO NOT, repeat, DO NOT
work the same way. A quiz follows, so pay attention!
This is how Vista x64 Setup works with an upgrade edition product key:
On a computer with a 32bit Windows installed:
You must boot the computer with the x64 dvd. You enter your upgrade edition
product key. Setup then searches the computer for an existing Windows that
is eligible for upgrade to Vista, which is any edition of Windows in the
Vista Upgrade Matrix. When it finds an existing Windows then Setup simply
proceeds. There is no message that you must run Setup from existing Windows
like there is with x86 Setup.
On a computer already running a 64bit Windows:
The user may boot with the x64 dvd or may run Setup from the desktop of the
existing Windows. A custom installation of Vista may be required, depending
on the existing Windows.
Details:
There is no requirement to run x64 Setup from within an existing Windows
like there is with x86 Setup for the simple reason that x64 Setup is a 64bit
program and cannot run within an x86 desktop. MS assumes that users
electing to install x64 Vista with an upgrade edition product key will be
replacing an x86 edition of Windows (probably XP) or installing in parallel.
As to doing a clean installation, keep the following in mind. Vista's disk
tools are not available when you start Setup from a desktop because Setup is
starting at Stage 2 of install. The disk tools are only available when you
start Setup with Stage 1. That means to use the disk tools to manipulate
partitions, format, and so on you must boot with the dvd to start Setup.
Since you can run x64 Setup by booting with the dvd, even when using an
upgrade edition product key, the disk tools are in fact available.
Here is the key point. Once x64 Setup verifies the existing Windows on the
computer the user is perfectly free to wipe out that existing Windows using
the disk tools and perform a clean installation.
It is not necessary to use an initial keyless installation in order to do a
clean installation of Vista x64 with an upgrade edition product key. Just
boot with the dvd.

Colin,
Are you certain you are correct here? I distinctly--but perhaps
incorrectly--remember that I read on my Windows Ultimate Upgrade
paperwork--that the upgrade will *only* install from an existing
installation of Windows. The Upgrade DVD will *not* boot the machine
cold, rather the Setup.exe must be run from within Windows. (That did
not *sound* correct to me, but I do remember reading it.)
I was able to boot my machine into x64 and then to run the Ultimate
Vista 64-bit installation from it, but I never reformatted my drive
and I never started "totally clean." I am using the new version of
the Retail Vista Ultimate Upgrade 64-bit with SP1 installed.
I am particularly interested in this question, because I have wondered
what would happen were my entire operating system to fail. Would I
then have to reinstall x64 before I could reinstall Vista?
I would like to believe you are correct here, and I hope I am wrong;
but my reading suggests that one must have a working version of an
eligible version is necessary for the Upgrade DVD to work.
Please tell me I am wrong. <g>
