The DOS environment variable COMSPEC is set at boot time to
point to the command processors file so that it may be reloaded
if needed.  Since you are booting from a floppy it will 
default to point to the copy found on your floppy or

COMPSEC=A:\COMMAND.COM

in order to allow DOS to reload COMMAND.COM from your C drive
place to following command in your AUTOEXEC.BAT file

Set COMSPEC=C:\COMMAND.COM

This assumes of course that the file actually resides in the
root rirectory of your C drive.
