ok i had a computer that messed up a long time ago and i couldnt find my system restore cd's that came with it (Windows ME) then i uploaded it with windows 98 , but it stills reads as windows ME when i use it and it starts up. But the problem is i just found the system restore cd's that came with it and now they wont work. so i made a start up disk and wanted to know what command to use with the startup disk to use the system restore cd's. thx to anyone that helpes
