Hi arulpandiyan.vadivel,
Your topic is in Jetson Nano category but it seems there’s not UEFI for Jetson Nano.
Are you using Orin Nano rather than Jetson Nano?
Are you using the devkit or custom board?
What’s your Jetpack version in use?
It seems you hit the similar issue as Cannot boot after Reset Settings on UEFI, which should be fixed in the latest Jetpack release.
