I have no DOS or Windows on my machine. I only use linux, one distro, SuSE 8.1.
The first time I installed linux, certain icons in KDE default were in the taskbar. I removed them eventually and added some of my own. Later, I reinstalled (not restore) linux and noticed KDE wasn't back at default config because my icons that I had added from the old installation were still there and the default ones I had removed before, were gone as well. How would I go about completely erasing everything on my hard disk and then trying a clean install of linux again?
