I wanted to reformat my HD so I typed 'deltree C:\windows' at the command prompt. It deleted and I used a boot disk and installed WinME. when it brought me to my desktop......I noticed the drivers to my video card were still installed .........I looked in the window\system and all the old files were still there......it wasn't DELETED. I don't know alot about reformatting..........so did I do anything wrong? Is their some dos commands I should type to make sure the windows\system was deleted? any help would be greatly appreciated.
