How do I install Linux on a desktop, laptop, or server?
Installing Linux on various devices involves several steps, which may slightly vary depending on the Linux distribution you choose. Here’s a general guide:
- Choose a Linux Distribution: First, decide which distribution (distro) you want to use. Popular options include Ubuntu, Fedora, Debian, and CentOS. Each has its strengths and target users.
- Prepare Installation Media: Download the ISO file of your chosen distro from its official website. Use a tool like Rufus (for Windows) or Etcher (for Windows, macOS, and Linux) to create a bootable USB drive from the ISO file.
- Backup Data: Before proceeding, back up any important data on the device where you intend to install Linux. Installing an operating system usually involves formatting partitions, which will erase data.
- Boot from the Installation Media: Insert the USB drive into your device, restart it, and enter the BIOS/UEFI settings (usually by pressing a key like F2, DEL, or ESC during startup) to set the USB as the first boot device. Save the changes and restart the device to boot from the USB.
- Start the Installation Process: Once booted into the live environment, launch the installation program (it usually starts automatically). Follow the on-screen instructions to select your language, keyboard layout, and other initial settings.
- Partitioning: You'll be prompted to partition the hard drive. You can choose to use the entire disk, use existing partitions, or manually set up partitions. For beginners, automatic partitioning is recommended.
- Installation and Configuration: The installer will copy the necessary files to the disk and set up the system. After this, you'll be asked to set up a user account and configure network settings.
- Finalize and Reboot: Once the installation is complete, remove the installation media and reboot the device. You should boot into your new Linux system.
- Post-Installation Setup: Update the system and install any additional software you need.

How can I dual-boot Linux with another operating system on my device?
Dual-booting Linux alongside another operating system like Windows involves the following steps:
- Backup Data: As with any major system change, back up your data first.
-
Shrink Windows Partition (if applicable):
- Open Windows Disk Management, right-click the Windows partition, and select "Shrink Volume" to create unallocated space for Linux.
- Prepare Installation Media: Follow the steps mentioned earlier to create a bootable USB drive with your chosen Linux distro.
- Boot into the Live Environment: Restart your device, enter BIOS/UEFI settings, and set the USB as the first boot device.
- Start the Linux Installer: Once booted into the live environment, start the installation process.
-
Partitioning: During the installation, choose "Something else" or "Manual" partitioning.
- Create a new partition in the unallocated space for Linux. Typically, you'll need at least three partitions: root ("/"), swap, and optionally, home ("/home").
- Ensure the Windows partition is not touched or formatted during this process.
-
Install the Bootloader: The Linux installer will ask where to install the bootloader (GRUB). It's usually recommended to install it on the same drive where Windows is installed (e.g.,
/dev/sda), not on a specific partition. - Complete the Installation: Follow the remaining steps to finish the installation. After rebooting, you should see a GRUB menu allowing you to choose between Linux and Windows.
-
Update GRUB (if necessary): In some cases, you may need to update GRUB to ensure both operating systems are recognized. In Linux, open a terminal and run
sudo update-grub.
By following these steps, you can successfully set up a dual-boot system with Linux and another operating system, allowing you to choose which OS to use each time you start your device.
