I have used windows 7 for some time now and am qjuite happy, however... I just recently upgraded to the latest verson and now my HP tablet 64 bit amd turion wont boot.
You need to "repair" your installation. Go to the bios and set boot from DVD/CD. let the computer boot from your Windows 7 install disk. You will then see a screen which has a "Repair your computer" option. Click on that and see if it works
