|You might be able to re-start the system restore process by launching safe mode.|
Just after the BIOS screen appears, press F8 repeatedly until the "Advanced boot options" menu appears.
From there select "Safe Mode". If the computer successfully boots into safe mode, you should recieve a dialogue stating "windows is running in safe mode, do you wish to proceed or run system restore".
Run the system restore and see if it managed to complete it this time (assuming that it will let you get this far).
