Well, no that's not really the problem. A drive already formatted NTFS should work fine (it always has for me). But in any case I just think it's still a good idea to reformat the disk using the Windows 7 DVD.
The problem is your computer doesn't seem to like booting from the DVD. I've had that problem before too. Many things can cause it. Faulty hardware or firmware, incorrect BIOS config or drive jumper settings, etc.
