Now, select what apps you'd like to install on your Ubuntu system. You have two choices here.

  1. Normal Installation
  2. Minimal Installation

By choosing normal installation, you can install all applications required for a full-fledged desktop, including web browser, office suite, games and media players.

By choosing minimal installation, you can install a minimal desktop version that has only a web browser and a few basic utilities.

You can additionally choose to download updates while installing Ubuntu. This will save you some time after installation. And also choose to install third-party software for your Graphics and WiFi drivers and other required media codec formats.

Here, I go with Normal Installation.

Next, choose the installation type. If your system currently has no operating systems, the installer will provide the following two options. You can choose any option that suits to you.

  1. Erase disk - Choosing this option will delete everything in your system. There is also additional option called "Advanced Features" that allows you to choose the following three options.
    • Use LVM with the new Ubuntu installation - If you want to resize, add, modify, take snapshot partitions, choose this option.
    • Encrypt the new installation for security - This option lets you to encrypt your Ubuntu system. You will need to choose a security key in the next wizard if you choose this option.
    • EXPERIMENTAL - Erase disk and use ZFS.
  2. Something else - It allows you to manually partition the hard drive yourself. You can set the custom size for each partition. It is opt for dual boot with Windows and/or other OS.

I go with the first option - Erase disk.
