I want to make a clean installation on Windows XP using a Dell Dimension 3000. It came with an installation disc. I accepted the license agreement, and chose the option to create a clean installation. Now I am on the part where I could choose a certain partition to make a clean installation on.

-: Partition 1 (FAT) 47 MB (39 MB free)
C: Partition 2 (NTFS) 34507 MB (6494 MB free)
F: Partition 3 (FAT32) 3585 MB (708 MB free)

I chose drive C the last time and it did NOT make a clean installation. If I choose drive C, I am afraid it will not make a clean installation. What should I do, and what drive should I choose?
When I chose partition 2: C, all my previous files were still there, so it was NOT a clean installation.
If I delete partition 2: Drive C, it will not let me do so, because a part of the drive is needed to make an installation of Windows.
I want to use drive C for a clean installation, but how can I do it?
