When I power up my laptop I get a choice of booting to a previous version of windows, windows 7, and F12 for more advanced options. It has been doing this for 2 years since upgrading to windows 7. I only want it to boot directly into windows 7. Since I have been getting this options from the time of windows 7 installation, is it possible the installation was done incorrectly? Windows 7 does operate correctly.
