Someone has erased the contents of the bootflash.

The fastest way to get the router running is to load the IOS into a USB flash drive and force the router tr boot via USB.

If you have, say, a Samsung Bar 16 Gb (image below) then this brand (and size) is supported by the router.

Samsung Bar 16 Gb

I had 2/3 different IOS on bootflash but boot was configured with only new IOS . It was issue with bootflash, after plug out/in this bootflash asked for formatting and then by the help

xmodem and following this link , we restored IOS and had fun to do it.
