Hi,     Can you verify flash

Hi,

     Can you verify flash is opening up properly and displaying IOS you wish to boot in it.  Please use below command in romon to verify.

rommon 1 >dev                    ### Lists the available disk ###

rommon 1 >dir flash:            ####verify your file is getting displayed and it is not in form of directory

Finally u can attempt manual boot attempt after u verify your file is present.

 

rommon 1 >boot flash:/c2800nm-adventerprisek9-mz.151-4.M7.bin

 

 

Thanks and regards
