Hi Jitendera,
When the router boots, it looks for the boot command stored
in NVRAM which is By default "boot system flash" means boot
from flash
then the router loads the IOS from flash.
If it is unable to load IOS from Flash, then it goes for
TFTP server then ROM etc
So during boot, Router goes to -
NVRAM > Flash > TFTP > ROM.
I think i made it clear.
