I got a new laptop today, a Toshiba with Windows 7 installed on it. Once all the Toshiba setup stuff had run I did the usual windows updates and played with it a little etc. Every time I boot it though, I get the same message, that Windows is preparing for it
It turns out the installation didn't actually complete properly. Probably because I was (stupidly) installing and uninstalling stuff (norton) while the rest of the installation was actually happening. Turning off my PC and holding 0 while turning on the power launched the recovery mode and I simply ran the setup again without touching anything.
The installation completed properly and the machine now runs great.
