I have pentium 3 p.c. that has got a hard drive that has been formatted. There is no operating system on it and I am trying to install Win98. When I turn the computer on the screen shows a C:\> prompt. I have no experience with DOS and wonder what to do. A neighbour tried various commands such as E:\SETUP.EXE and got "invalid drive specification". We also tried using other letters from A to F and had no joy. The floppy drive tried to read but a message saying "Not ready reading drive B". Please can anyone help? It must be a relatively easy operation when you know how! It is driving me mad as I desperately need a back-up p.c.
