How do I remove the second copy of Windows from my computer?

by on March 7, 2009

Q: I own a hard drive that had many critical files removed and windows could not start. The first error was missing NTLDR I reinstalled it from the windows disk. I then installed another copy of windows on the same partition. Since the original copy is not working properly yet, only the new copy of windows starts. I need to know how to remove the new copy of windows so I can restore the old copy and remove important data before it’s too late.
