BIG Computer Problem
I have a used computer I bought yesterday and I have a problem. I was adding parts for a computer that "died" and I ran into a problem. I added some RAM and it worked fine. The problem came when I tried to add the hard drive. I pluged it in and while it was starting it said it couldn't find the boot file. I shut it down, removed the hard drive and now in says " NTLDR is missing". WHAT HAPPENED???
