Hello,
it means something wrong with filesystem - flash is empty or filesystem corrupted. Try to reload an image and make sure you use the right one for your router.
Here is software upgrade procedure:
Thanks.

Your Flash is Full... Squeeze Previous IOS .. make some room for New IOS.
In rommon Mode give command " Sh flash "
