I have tried every possible solution I can find to try to resolve this error. From a repair install to the last resort which was a fresh re-install of windows 7. Every time I try to install it upon reboot it fails at configuring: 7% and reverts changes.
There is no antivirus or any other software that could interfere so I wonder if a driver could be causing the problem. Microsoft have been useless as usual, so hope someone here can help?
