We see the installation summery field and need to change some setting according to our location and situation. In localization field, I will change the location which I live and keyboard which I use but there is a place into Date & Time field that we need to change after we set the network connection on because I want to use global NTP resources which located on CentOS servers. If you have NTP Server in your location, you can use it also. I’m going to mention it when the time comes.

Now I set my password and I need to apply twice because I set a weak password and system wants me to press on the Done button twice to accept the weak password. You should choose a strong password if you use it on real systems. This is a demo installation and I’m using a weak password.
