This is because Windows will already automatically create a new correctly configured NTFS Partition. Do Not Format, by formatting as opposed to re-partitioning you are in effect using the original partition Original Windows Setup discs already have this option, during the setup of Windows, to remove the Partition (linked below) But in some cases even the Windows Setup has trouble removing the existing partition and a 3rd party disc must be used. Member LookinAround has provided excellent info here on Gparted Partitioning Tool, to help remove existing partitions http://www.techspot.com/vb/post720766-3.html To be absolutely clear on how to re-install Windows clean, here are some excellent guides already provided on the web: Microsoft's Windows XP Professional Repair Install step by step (* Including Delete Partition) http://www.windowsxpprofessional.windowsreinstall.com/sp2sp3installxpcdoldhdd/indexfullpage.htm Microsoft's Windows XP Home Repair Install step by step (* Including Delete Partition) http://www.windowsxphome.windowsreinstall.com/sp2sp3installxpcdoldhdd/indexfullpage.htm * Warning deleting the Partition will remove all User data and Windows system files Windows Vista, guides here: http://www.windowsreinstall.com/winvista/index.htm Windows 7, info here: http://windows7.windowsreinstall.com/ Restore Discs Many computers now come with Windows Restore Discs. These are not the original Windows Setup Discs These "Restore" discs always remove the old partition and install Windows on a brand newly created partition Therefore, removing the original partition is not required. But obviously all users still need to backup data first ---------------------- I hope this information helps others, I actually created it so as I could quote or link to it, in relevant threads :grinthumb .
