I Try to update Windows Vista SP1 towards Windows Vista SP2 (KB948465).
The installation ends with error 0x80004005. I also tried already a "Clean install", same error happens.
The following article explains the reason: http://support.microsoft.com/kb/971204
Cause: When you install Vista SP2, the Vista SP2 installer must update the system boot files. If third-party disk management tools are used to "clone" disks or partitions, the SP2 installer will be unable to uniquely identify the correct system boot files.
Resolution: To work around this issue, turn off the computer and physically unplug all drives that are not required for starting Windows. Power up the computer and restart the service pack installation.
If the workaround is not successful, the alternative is to perform a clean-install.
The only third party product in this area, I use is Acronis True Image 10 and I remember, that I cloned the system partition with Acronis True Image 10 to a new disk about a year ago. I'm still using the old disk with new partitions at the same system as data store.
I'm not very happy to run through this disk unplug stuff ending up with different drive letters and so on.
Now my question: Is there any idea from Acronis to solve the problem without unpluging disks.
