The problem you report suggests that although there is a hard drive
in the system, it is not bootable.  That can be the result of a lack of a
valid partition, a valid partition not set to ACTIVE, the partition is not
properly formatted and/or there is no operating system on the drive, which
only requires COMMAND.COM to exist.

In other words:
    The hard drive must be recognized by the BIOS
    The hard drive must have a proper partition and be set to "active"
    The hard drive must be formatted, (or at least the primary partition)
    The hard drive must have an operating system or at least the command
        operator:  Command.com on the drive, (this is done by using a bootable
        MS Dos or Windows floppy, then using the command  SYS C:\

I hope this explains your possible problem.
