that's correct. the bootmgr knows nothing of it and it will be just allocated space (but ALL programs will not be usable)The HD that I am adding has OS I should not have to take it off right?
You don't need to, but can it you so choose. With the drive connected to the new system, you can drag-n-drop files or folders to the system HD, or just access them where they are.Is there a way I can wipe clean the Drive with XP home. would that slove me problem?
