I would like to upgrade my HD in a DeLL XPS system running Home Premium
(upgraded from XP Pro). Is there a step by step available somewhere on how
to best do this without having to go through the re-registration process
once the OS is on the new drive?
The new drive should come with a copy utility to clone the old drive to the
new. If it's a white box drive, then download the utility from the drive
manufacturer's web site.
Another option is to use a commercial program to clone the old to the new,
such as Acronis True Image Home, version 10, as Richard said. It works well
in Vista with the added advantage that you now have an excellent backup and
recovery solution for use in Vista. Make sure you update it to the latest
version. Check the discount retailers for the best price (such as
Newegg.com), much better than from Acronis direct.
The key point, in the cloning, is after the cloning is done, before booting
for the first time from the new drive, remove the old drive so only the new
one is installed. After that you can reinstall the old drive, format it,
and use it as additional storage.
