I have a Dell Insipron 1000 notebook computer that came with windows XP home edition on it. I really don't like XP so I formatted the drive (NTFS) and put windows 2000 pro on it. What's really annoying me is that when the computer boots up, it gives me a choice of what OS to boot from. Windows 2000 Pro or Windows XP. I don't understand this because Windows XP is not on the computer anymore. Any advice? Thanks!
