Re: changing OS
If your going to install winXP pro then yes u will have to format the drive and stick in the installation cd and follow the instructions. Its actually really easy, i have done it many times without anyone showing me. U may be able to get away without formatiing, but do urself a favour, format. It cleans the drive and starts u off fresh! Its the proper way to do it. Once again, only do it if its winXP pro. No need to go from XP media centre to xp Home.
