How to retrieve my bookmark folders in Google Chrome on a Macbook Pro?

Hi, yesterday I did a clean install on my Macbook Pro Retina to install Mavericks since I had bootcamp it was causing some trouble to let me update to Mavericks.

But after my clean install now I’m on Google Chrome I’ve just noticed all of my bookmark folders are gone. Does anyone know how can I retrieve them? Help please :c It’s a lot of bookmarks that I had.
