A friend wants to go back to Windows98. He feels more comfortable with it, but his latest PC came loaded with Millennium. Ive tried to fdisk but keep getting error messages. I tried to restart with Windows98 boot disk and get as far as the startup wizzard, then stops the upload and informs me that I should use an upgraded version. Is it possible to restart in DOS mode, reformat the C drive, and then load windows98? And if so, whats the step by step. Any help would be greatly appreciated.
