How do I get Samsung Galaxy A3 to stop booting into recovery mode

Hello,
I am new to rooting. I rooted my Samsung Galaxy A3. Now I have exclamation point on turning on and the I get "Android System Recovery <3e> KTU84P. A300FXXUIANU." with the following options:
reboot system now
apply update from ADB
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
I have selected "reboot sytem now" and everything works fine.
My question is how do I get the fone to stop booting into recovery mode and having to select "reboot system now" everytime I switch it on?
