NT Installation Failure

Here is a problem I’ve encountered several times and cant’ figure out. I am doing a clean install of NT 4.0 WS. The first part of installation(text-based) seems to fine. I create and format my partitions and create the default \WINNT directory. I amtold the first part is completed and the system will reboot to continue installation. After the reboot, I receive the error message “Missing Operating System” or a very similar message. I’ve tried swapping drives, playing with master/slave settings,changing IDE cables, changing BIOS settings. Nothing seems to help! Any advice on reason(s) this happens. It’s not the first time I’ve encountered this and never got past it.
