I have that many system problems that I need to format my hdd and re-install windows on a clean slate. I have ntfs, so I cannot do what I used to do and load win 98 boot disk and format c:. My version of xp is upgrade. What do I have to do to format my drive? If I do a re-install of windows inside the GUI, will it wipe out existing installation including folders? Help, as I am totally confused!
