During the installation, you will be prompted to the disk partitioning process of your hard drive. Once you finish partitioning your hard drive, select which package you want to install, including standard system utilities.
It is important to note that if you choose to install the entire disk, this installer will erase all data on the disk and install Debian as the sole operating system.
During the installation, you will be prompted to create a user account. This user account will not have root user privileges, so you must use the "sudo" command or enter the root user name and password to perform certain administrative tasks.
Creating a strong root password for your user account would be best to help protect your system.
