I have just installed a new Magento and add some new categories. However I could not find it from my Magento frontend
Its common question from those who have installed new Magento. All categories have to be added under the default category. To make ensure it is correct. Click on the default category section from Magento backend – Select proper “Store”, and then click Add subcategory. Make sure it is “Active” and set “Is Anchor” as enabled.
