Re: no magic number

You may have a problem with the flash card in your router. Try these suggestions taken from the following link:

The Flash card is removed or badly inserted. Verify the presence of the Flash card by running the show flash command:

router(boot)#show flash

%Device in REMOVED state

Insert or reseat the Flash. If the problem persists, replace the Flash card. If that doesn't resolve the problem, replace the router.

The Flash is empty or the filesystem is corrupted. Copy a valid image on the Flash, and while copying, you will be prompted to erase the old Flash (if one exists). Then reload the router.

Refer to Software Installation and Upgrade Procedures for instructions on how to copy a valid image onto the Flash.
