Hi

It looks like a problem with the image or it could be a corrupted/damaged image. Have you verified if the IOS is on the flash:

dir flash:

Hi,

Yes when i issue dir flash i can see the image file name and when i issue from switch: mode boot the image it is booted from the the IOS and i can access the switch and do all configuration but when the switch turned off it goes to switch: mode.

i have used the suggested ios file name from cisco.

Hi

There are 2 ways to correct it, one if you are over rommon and the the other option if you are over the proper image running. 

If you are in rommon (switch:) mode, execute this command:

confreg 0x2102

http://www.cisco.com/c/en/us/support/docs/routers/10000-series-routers/50421-config-register-use.html#anc13

If you are running the proper image and you can execute your configurations, you need to change the register to 2102

conf t

config-register 0x2102

write memory

*Once you have execute the command you can reboot the switch and verify the proper functionability.

Hope it is useful

In Catalyst WS-C2960G-24TC-L  configuration register command invalid even confreg 

^ % Invalid input detected at '^' marker.

Hi

Did you try over Switch mode (stop at step 6) Clic?

confreg 0x2102

then 

press reset

Hi

Actually the switches dont support nat.

Without a console log, we are shooting in the dark.

If you can issue" boot flash:path-to-image.bin", this probably means the image is fine but the boot var isn't set correctly.
I think the syntax is set BOOT flash:path-to-image.bin in ROMON
