Hi, your OS image file is missing. you need to install/copy image file back to the switch. check below for newest OS upgrade

If the switch is in ROMMON, post the complete output to the following commands: 

dir flash:
set

Please refer to attachment for the Emergency-Install procedure.

Hello DO5, 

This error means the BOOT variable is not properly set and|or the device is trying to boot from .bin file that is not storage in flash.

 Using the "set" command from ROMMON mode you can identify how the BOOT variable is set. In addition form the output of dir flash: command you can double check if the .bin file is saved in flash: 

You can look  also for a pacakeges.conf file in the flash memory. If this file is there you can check which IOS XE code is expanded on it:

switch:more flash;packages.conf 

Finally, based on which file is available in flash: either .bin file or packages.conf you can try setting up the BOOT variable:

BOOT = flash:packages.conf 

or

BOOT = flash:<file.bin>

HTH
