Hi Tamer,
you should check the value of the config-register - You can check this using the show version command. The value is shown in the last line of the show version output. It should be set to 0x2102.
2610#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
2610(config)#config-register 0x2102
2610(config)#^Z
Perhaps you have other files on the Flash - If the first file in the Flash is not the Cisco IOS Software image, but a configuration file or something else, then you need to configure a boot system statement in order to boot the specified image. Otherwise, the router will try to boot with the configuration file or the first file in the Flash; this will not work. If there is only one file in the Flash which is the Cisco IOS Software image, then this step is not necessary.
2610#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
2610(config)#no boot system
2610(config)#boot system flash c2600-i-mz.121-14.bin
2610(config)#^Z
regards
Peter
