How to exit Nandroid backup

[Samtheman7]

i have an ATT galaxy S3, and I just finished a nandroid backup. However, CWM Recovery is now giving me the option to restore the ROM I just backed up (which is a stock ROM, its my first time) or just reboot. What should I do? All I want is to return to my Stock Rom and continue using my phone. any help is appreciated.

You should select 'reboot system now'.
After it says the backup has completed.
