On NVRAM.
NVRAM Stores startup-config. The IOS (Internetwork Operating System) is stored in the flash. Both flash and NVRAM are non volatile storages but there is a major difference.
wr or copy running-config startup config
When a router boots up, it follows a default order to search for startup configuration information. First, it checks the non-volatile memory (NVRAM) for the startup configuration file, typically named "startup-config." If it doesn't find a valid configuration there, it may look for a configuration file in a TFTP server, and if that fails, the router will proceed with its default settings, often leading to a mode where no configurations are applied.

Boot Configuration Data (BCD)
NVRAM is that router component in which start up configuration file is stored.
When a Cisco router is booted up for the first time, or is reloaded, the router will look into its Non-Volatile RAM (NVRAM) for the startup configuration file. Setup Mode is usedto configure a Cisco router or switch after start up to create a startup configuration file.
NVRAM
It will boot into ROMMON mode. It will ignore the start-up configuration file. It will look for the start-up configuration file on the TFTP server. It will attempt to load the start-up configuration file that is stored in NVRAM.
