Ethernet Connection: If using a wired connection, it will likely be detected automatically.

Installation Type

This is a crucial step where you decide how Ubuntu will be installed on your hard drive.

Install Ubuntu alongside [Existing OS]: If you have another operating system (like Windows) installed, this option allows you to create a dual-boot system. The installer will suggest a partition size, but you can adjust it manually.
Erase disk and install Ubuntu: This option will wipe the entire hard drive and install Ubuntu as the sole operating system. Use with extreme caution, as all data on the selected disk will be lost.
Something else: This option provides advanced control over disk partitioning. It’s suitable for users who want to manually create, delete, and resize partitions, or when installing Ubuntu on a specific drive without affecting others. This is particularly relevant for specialized deployments where custom partitioning is required for performance or data management.
- Manual Partitioning (for advanced users):
  - Create a Root Partition (/): This is where the main operating system files will reside. A recommended size is at least 20 GB, but more is better for future software installations.
  - Create a Swap Partition: Used as virtual RAM when your physical RAM is full. A common practice is to make it equal to your RAM size, or at least 2 GB.
  - Create a Home Partition (/home): This is where your personal files and user data will be stored. Separating /home from the root partition makes it easier to reinstall Ubuntu later without losing your personal data. The remaining free space can be allocated here.
  - EFI System Partition (if using UEFI): If your system uses UEFI, you will need a small (around 100-500 MB) FAT32 partition flagged as EFI System Partition.

User Account and Settings

Your Name & Computer’s Name: Enter your full name and choose a name for your computer.
Username & Password: Create a username and a strong password. You can choose to log in automatically or require a password.
Install Third-Party Software: It is generally recommended to check the box for installing proprietary drivers for graphics, Wi-Fi hardware, and media codecs. This ensures better hardware compatibility and playback of various media formats.
