SUMMARY

The NEC Versa 4050C computer allows you to inter-exchange or swap between a floppy disk drive and an IDE CD-ROM drive. Windows NT does not allow you to start with any media component. For example, you cannot start Windows NT with a floppy disk drive and then immediately restart your component with a an IDE CD-ROM drive. A "STOP: 0x0000007B: Inaccessible Boot Device" blue screen appears if you start with a component that has not been configured in Windows NT.

This article explains how to start Windows NT on a NEC Versa 4050C computer.
