Re-install MOBO problem

[fogstratus]

First-"Thanks" to those who helped me overcome a new MOBO install - a new hard drive solved my problems!

However, I discovered that I needed to access the two hard drives I removed (Yes! I didn't do all the back-ups, because I didn't consider that I would be unable to access them from the new MOBO). I have re-installed the old MOBO, with the old CPU, and everything else. Now I am getting an error message, "NTLDR Missing." I do not know what the "NTLDR" is, although it sound familiar. Can anyone enlighten me?

Thanks,

Steve

Did you delete any files on the drive, or do you have a floppy still in the floppy drive when you boot up?
