Windows 7 Upgrade fails to complete
Posted on 2013-06-16
Anyone know how to recover from a Widows Vista -> Windows 7 Home Premium upgrade that failed to complete?
The upgrade was on the last step, then stopped at 72% for an hour or so - I assumed the process was 'hung' and rebooted the PC, thinking it would resume upon booting.
However, instead of proceeding / completing the upgrade - it gives me an error message immediately after the Setup is Starting Services' message:
"The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. To Install Windows, click "OK" to restart the computer and then restart the installation"
When i try that (Boot from the Win 7 upgrade DVD) and choose 'Upgrade' - i get the following error message in the 'Compatability Report' screen
"The computer started using the Windows installation disc. Remove the Windows installation disc and restart your computer so that Windows starts normally. Then insert the Windows installation disc and restart the upgrade. (Do not select "Custom (advanced)" to perform an upgrade. "Custom (advanced)" installs a new copy of Windows and deletes your programs and settings.)"
Doing what they suggest above does not work as it just repeats the "The Computer restarted unexpectedly error message listed above and the process (Catch 22) repeats
At this point, I don't have an OS to boot clean to - is there anyway to continue the upgrade process via command prompt or something???
Additionally, Booting from the DVD and trying 'Startup Repair' does nothing either.
Any help is greatly appreciated!
