Hi Parvinder

Do make use of TFTP copying to copy the required IOS code onto your flash.

Once you are done with that do define the boot loader(boot system command) statement pointing the ios code file saved in your flash.

After doing the same make sure you have both the ios code in flash as well as your boot system command appears in your config.

Also make sure that you have correct config register value set in your config..

The loaded IOS image is running from RAM

Current boot field value is 0010 (default).

This causes the system to boot the image from default boot filename "cisco2-3600" if boot from flash fails, in your case there is no IOS inflash:

Enabling the boot system command override the default filename for booting over the network from a TFTP server.

As mentioned in earlier post, you need to upload IOS in flash from TFTP and then set the boot system command to allow router to boot from flash:

hope it helps .... rate if it does ...
