I just installed win 2000 on my second partition (drive D) and have NT4 on Drive C. I kept NT4 just in case Win 2000 did not work. Now, everything is running fine and I would like to delete NT4. Can I just get into win 2000 and under "My Computer" do a right click and do a quick format on my C: drive? Will I have any problems running my OS off my D drive? Thanks
