N.B.; Problem solved.
Thanks to the miracle of MSDN subscriptions, I’m privileged to be in the possession of a (legally licensed and perfectly legitimate) copy of the brand new release of Windows 7 …. not the RC, mind, the RTM made available so that manufacturers and the like can prepare computer for release on the 22nd and the like.
Seeing as I’ve spent a great deal of time getting my Windows Vista Ultimate machine tuned to perfection, I really wasn’t looking forward to starting from scratch, so I decided to try my luck with an upgrade…. The ISO was downloaded and burned to disk, and I was ready to go. With Windows Vista running, I inserted the DVD and began the upgrade process, only to come across…
Windows Setup experienced an unexpected error. To install Windows, restart the installation (…. along with the error code 0×0.)
Rummaging the web for advice proved quite fruitless, as the OS is brand new, and most of the comments in the Google search results related to Windows XP -> Vista upgrades.
To cut a long story short, I’ve discovered that the problem was two-fold … firstly, the presence fo a running copy of AVG managed to bring the process to a halt, though I suspect that this would have been the case had I any other third party AV running. So, using the process manager, I carefully bought all AV related process to a halt. Then I had to deal with the second issue, which was the fact that the install simply did not want to work from a DVD. The ISO itself was intact, and the disk was burned on quality media at a reasonable speed with reliable hardware and software.
The solution: Mount the ISO as a virtual drive using ISOmagic. The installation began without a hitch, and concluded seamlessly.
As a side note, here are some other things that I tried as a result of rooting about for solutions in forums, none of which made any difference.
** Turning off the DMA feature for the IDE channel of the drive you wish to install the OS on
** Burning the disk at stupidly slow speeds (this irks me – modern drives burn perfectly well at good speeds if you have half-decent media)
** Changing the order of the drives as they are physically connected to the motherboad (sigh)
I’m happy to answer any questions with regards to the install, should you have any… feel free to leave comments attached to this post.
Happy days….
ADDITIONAL; August 20. Those people not wishing to perform an upgrade might try re-downloading the ISO, running am MD5/CRC check, and burning the ISO to different brand media. Despite what you read elsewhere, my experience leads me to believe that burn speed is pretty much NEVER the root of issues … not with a quality optical drive and decemt media, anyway.
