I'm trying to format my hardrive so i can do a completely fresh install of XP and it wont let me. I just ran the setup but all the unwanted files are still on the hardrive. On the second attempt I tried to delete the partitions but it says I cannot as some of the setup files are contained in there, even when I change the BIOS settings to 'boot from cd'. Can anyone help with this? I just wanna delete it all. Also I tried using 'format c:' from the command prompt but I am unable to dismount from the drive. I miss DOS Thanks for any help!
