Partitioning is the process of dividing a hard drive into smaller sections or partitions. Each partition can be used to store data, programs, and other files. This is an important step in installing an operating system, including Ubuntu. In this article, we will dive deeper into the partitioning process in Ubuntu, including the different types of partitions, how to create and manage them, and some best practices to follow.
Types of Partitions
Before we dive into the process of partitioning, it’s important to understand the different types of partitions you can create in Ubuntu:
Primary partition: A primary partition is a type of partition that can be bootable, meaning it can contain an operating system. Each hard drive can have up to four primary partitions, or three primary partitions and one extended partition.
Extended partition: An extended partition is a special type of partition that can contain one or more logical partitions. Logical partitions cannot be bootable and are typically used to store data and files.
Logical partition: A logical partition is a partition that is contained within an extended partition. A hard drive can have multiple logical partitions, and each logical partition can have its own file system.
Creating Partitions in Ubuntu
When you install Ubuntu, you will be prompted to create partitions for the operating system. If you choose to create partitions manually, you will need to follow these steps:
Boot from the Ubuntu installation media and select “Install Ubuntu”.
Follow the on-screen instructions until you reach the “Installation Type” screen.
Select “Something Else” and click “Continue”.
You will see a list of your hard drives and partitions. If you want to create a new partition, select the unallocated space and click the “+” button.
Enter the partition size, file system, and mount point. You can also select whether to make the partition a primary or logical partition.
Click “OK” to create the partition.
Repeat the process to create additional partitions as needed.
Managing Partitions in Ubuntu
Once you have created partitions in Ubuntu, you can manage them using the Disk Utility tool. Here’s how:
Open the Dash by clicking the Ubuntu icon in the top left corner of the screen.
Type “Disk Utility” in the search bar and click on the application to open it.
You will see a list of your hard drives and partitions. Click on a partition to see more details, such as the file system, mount point, and available space.
You can perform various actions on a partition, such as formatting it, changing its mount point, or resizing it.
Best Practices for Partitioning in Ubuntu
Here are some best practices to follow when partitioning a hard drive in Ubuntu:
Separate the operating system and user data: It’s a good idea to create separate partitions for the operating system and user data. This can make it easier to back up and restore data, and can also improve performance.
Allocate enough space for the operating system: Ubuntu requires a minimum of 25 GB of disk space, but it’s recommended to allocate at least 50 GB to the operating system partition to allow for future updates and installations.
Create a separate swap partition: A swap partition is used by Ubuntu as virtual memory when the physical memory (RAM) is full. It’s recommended to create a swap partition that is at least the size of the RAM on your system.
Use a file system that meets your needs: Ubuntu supports several file systems, including ext4, which is the default file system. However, you can also use other file systems, such as NTFS or FAT32, depending on your needs.
Consider using LVM: Logical Volume Manager (LVM) is a powerful tool
