Hello,
Since the flash does not have an image, the router is booting to ROMMON
mode. To address this you have couple of options:
Option 1: If you have a spare router (any router that accepts the flash
card), then you can put the flash card in there, then connect that router to
the tftp server, copy the image (ignore the warning) and then put the card
back in router.
Option 2: If you do not have a spare router, then you can load the image via
tftpdnld option. Here is the procedure for tftpdnld recovery.

Please make sure that you are using a TFTP server that supports image size
greater than 16 MB (I would suggest using tftpd32).
Hope this helps.
