Default [Q] Pb ROOTING E330S

Hello,
I'm a French Newbie with this phone and I'd like to root it to save it before flashing it with a French ROM instead of the Korean I have.
My phone is on android 4.3

I tryied the following method:

I'm supposed to select "install ZIP" in the recovery mode but I only have:
reboot- apply update from ADM - apply update from external storage - wipe data/factory reset - wipe cache partition - apply update from cache
If I select apply update from external storage, I can see the ZIP file I've pasted on my SD card but I did not go further becaus I'm not sure of what I'm doing because the options are not the same "install ZIP" vs "apply update".

Could youhelp me please?
