I've got a strange problem where the router won't boot with the startup config. When I type 'sho start' I see my config displayed but when I type 'sho run' it shows the generic config with none of the changes I made. Also, every time I power cycle the router it comes up with the following:
Would you like to enter the initial configuration dialog? [yes/no]:
When I type 'copy start run' and then 'sho run' I see my configuration changes in the running config. However when I power cycle the router it comes back up wit the initial configuration dialog and none of my configuration changes are in the running config????
I tried going through the initial configuration dialog, choosing the basic setup and assigning just a hostname and ip address to e0/0 but when I power cycle the router it still comes back up with the initial configuration dialog and doesn't have any of my changes in the running config.
What the heck is going on here?

Do a SH VER, and check the config register value.
For most routers it should show 0x2102
If it doesn't, you can change it from global config with "confreg 0x2102"
It may be set to ignore the startup config, that is a common step in doing a password recovery.
Good Luck

Hi,
Issue the show version command and check the last line where it says config register.
If it is not set to (config-register 0x2102) then your router will not load startup-configuration file.
To resolve this go to configuration mode and change the value to be config-register 0x2102.
then copy startup-config to running-config and
then write memory (or copy running-configuration to startup-configuration) and reload the router.
your router should now load the startup-configuration.
Hope This Helps
