Where will a router first search for a valid IOS image to load when powered on?

Explanation:
When you power a router on, the bootstrap in ROM looks first in flash memory for a valid IOS image to boot. Flash is the primary storage for the IOS image, so if a valid image is found there, the router loads it and proceeds with the startup. If flash doesn’t contain a usable image, the device can fall back to ROM’s minimal IOS or other recovery methods (like booting from a network source), but the initial check is always flash memory.
