Hi.Am trying to do new installation (clean install) of windows xp pro and cant seem to get the option of formatting the drive.All it seems to do is rewrite over the previous installations(even though I choose new installation option).Since trying to reinstall I also keep getting the error "cant find c:\windows\system32\tools\delfolders.exe." It doesnt seem to be causing any problems as such as I can still use my computer but I would really like to format and get rid of any crap.Any ideas?Also clicking on C drive in My Computer and then clicking file and then choosing format, also says that windows cannot format this drive.Please close any utilities ................. and try again.No luck.Thanks.Darren.
