I have a computer that WinME was installed on, however, it was not installed with the option to return to previous OS and I want to put Win2k on it. I can't goto Add/Remove Programs and fix this. I have tried installing Win2k from ME, doesnt work, I've tried installing 98SE from ME, doesnt work. I have used a startup disk and the computer locks up before it starts installing Win98SE, and as you know, Win2k wont install from DOS. I have renamed win.com and it still started up normal. Maybe Microsoft hides win.com in another file, like they do logo.sys so if u delete it, it'll get logo from io.sys. If anybody could help me with this or knows anything of what I should do, without reformating, please help me!
