Add yet another issue to this mess. When I try to start 4.0 it stops at the MS-DOS screen and won't go further. I can't load Tools and I've tried a few of the other steps thru the "black screen" search, such as going thru Transporter but no dice (says it can't find the .hdd). So it hangs at the startup screen with these lines: "Trying to boot from Primary Master IDE drive.." and "NTDLR is missing". After that it says, "Press Ctrl+Alt+Del to restart". What to do next?
