I recently moved, and turned my computer off and disconnected it. When I went to set it up at the new place I got a message saying NTLDR is missing, I called Dell And they told me to insert my windows disc, I did that but my cd rom wouldn't start. I went to f2 at start up and cannot find any cd roms, I have two burners a NEC 3550 and A Samsung 16x with lightscribe, neither one of these show as working. Any suggestions? Please help if you can. Thanks in advance.
