Hello @Tahir Munir,

The error message you're encountering during the boot process of your Cisco router indicates that the router is unable to determine the first executable file name on the "flash:" device. In otjer words, the router is unable to locate the appropriate IOS image to load from the flash memory.

You might need to enter the router into ROMmon mode and attempt to recover the system.

Because password recovery is disabled, then you have a very short interval after the image is loaded to hit break and get a prompt that asks if you want to recover the router. 

Note that 2821 should have a flash card. If you eject the flash card and reboot, the router will boot into ROMmon.

Tell us when you are in ROMmon.
