Was running Windows 2K Pro on drive C: and also wanted to use Win XP so I installed another drive D: and installed XP Pro on it. The dual drive worked fine but all the initiating files are on C drive. I changed the boot.in so XP Pro which is on D: starts, this runs fine Now want to remove the C: drive and the Win 2K Pro files and just have XP Pro that is on D drive for my system but am unsure of what files I need on D drive to let it run without the old C drive in place. I copied the ntldr, NTDetect.com, boot.ini, & cmldr files over to D: drive and tried to boot up without the old C: drive and made my D: the master with no joy. What do I have to do to get my Win XP to boot without C: drive being installed?
