Linux Mint 18.3 has been released in wild by the Linux Mint project developer team as a new long term support edition which will receive support and security updates until 2021.

This tutorial will guide you on how you can install Linux Mint 18.3 in dual-boot with a variant Microsoft Operating System, such as Windows 8, 8.1 or 10, on machines with EFI firmware and a pre-installed version of Microsoft OS.

If you’re looking for a non dual-boot installation on Laptop, Desktop or Virtual Machine, you should read: Installation of Linux Mint 18.

Assuming that your laptop or desktop system comes pre-installed with Windows 10 or Windows 8.1 or 8 you should enter UEFI menu and disable the following settings: Secure Boot and Fast Boot features.


If the computer has no pre-installed OS and you intend to use Linux and Windows in dual-boot, first install Microsoft Windows and then proceed with Linux Mint 18 installation.

Download Linux Mint 18

  1. Linux Mint 18 ISO image – https://www.linuxmint.com/download.php

In case you own a UEFI computer stay away from the 32-bit version of Linux Mint because it will only boot and work with BIOS machines, while the 64-bit ISO image can boot with BIOS or UEFI computers.

Step 1: Shrink HDD Space for Dual-Boot

1. In case your computer comes pre-installed with Microsoft Windows on a single partition, logon to Windows system with a user who has administrator privileges, press [Win+r] keys to open run prompt and type the following command in order to open Disk Management tool.

diskmgmt.msc
Open Windows Disk Management

Open Windows Disk Management

2. Right click on C: partition and select Shrink Volume in order to resize the partition.

Close Disk Management utility, place Linux Mint DVD or USB bootable image in the appropriate drive and reboot the computer in order to start with Linux Mint 18 installation.

In case you’re booting Linux Mint for installation from a USB dive in UEFI mode make sure you’ve created the bootable USB stick using a utility such as Rufus, which is UEFI compatible, otherwise your USB bootable drive won’t boot.

Step 2: Installation of Linux Mint 18

5. After reboot, press the special function key and instruct the machine firmware (UEFI) to boot-up from the appropriate DVD or USB drive (the special function keys usually are F12, F10 or F2 depending on the motherboard manufacturer).

Once the media boots-up a new screen should appear on your monitor. Choose Start Linux Mint 18 Cinnamon and hit Enter to continue.

Select Start Linux Mint Cinnamon-Install

6. Wait until the system loads into RAM in order to run in live-mode and open the installer by double clicking on Install Linux Mint icon.

Choose the language you wish to perform the installation and click on Continue button to proceed further.

7. On the next screen hit on Continue button to proceed further. Third-party software can be automatically download and installed on this step by checking the check-box.

The recommendation would be to leave the box unchecked for the moment and manually install proprietary software later, after the installation process completes.

8. At the next screen you can choose the Installation Type. If Windows Boot manager is automatically detected you can choose to Install Linux Mint alongside Windows Boot Manager. This option ensures that the HDD will be automatically partitioned by the installer without any data loss.

The second option, Erase disk and install Ubuntu, should be avoided for dual-boot because is potentially dangerous and will wipe-out your disk.

For a more flexible partition layout you should go with Something else option and hit on Continue button to proceed further.

9. Now let’s create the partition layout for Linux Mint 18. I would recommend that you create three partitions, one for / (root), one for /home accounts data and one partition for swap.

First create the swap partition. Select the free space and hit on the + icon from below. On this partition use the following settings and hit OK to create the partition:

Size = 1024 MB
Type for the new partition = Primary
Location for the new partition = Beginning of this space
Use as = swap area
Select Free Partition Space

Select Free Partition Space

Create Swap Partition

10. Using the same steps as above create the /(root) partition with the below settings:

Size = minimum 20 GB
Type for the new partition = Primary
Location for the new partition = Beginning of this space
Use as = EXT4 journaling file system
Mount point = /
Select Free Space

Select Free Space

Create Root Partition

11. Finally, create the home slice with the below settings (use all the available free space to create home partition).

Home partition is the place where all documents for user accounts will be stored by default, except the root account. In case of a system failure you can reinstall the operating system for scratch without touching or losing the settings and documents of all users.

Size = remaining free space
Type for the new partition = Primary
Location for the new partition = Beginning Use as = EXT4 journaling file system
Mount point = /home
Create Home Partition

12. After finishing creating the partition layout, select Windows Boot Manager as the device for installing the Grub boot loader and hit on Install Now button in order to commit changes to disk and proceed with the installation.

Next a new pop-up window will ask you if you agree with committing changes to disk. Hit on Continue to accept changes and the installer will now start to write changes to disk.

17. After reboot, the system will first boot-up in Grub, with Linux Mint as the first boot option which will be automatically started after 10 seconds. Form here you can further instruct the computer to boot in Windows or Linux.

On computers with newer UEFI firmware the Grub boot loader won’t be displayed by default and the machine will automatically boot-up in Windows.

In order to boot into Linux you must press the special function boot key after restart and from there to further select what OS you wish to start.

In order to change the default boot order enter UEFI settings, select your default OS and save the changes. Review the vendor’s manual in order to detect the special function keys used for boot or for entering UEFI settings.

18. After the system finishes loading, log in to Linux Mint 18 by using the credentials created during the installation process. Fire-up a Terminal window and start the update process from command line by running the following commands:

$ sudo apt-get update
$ sudo apt-get upgrade

That’s it! You have successfully installed the latest version of Linux Mint 18 on your device. You will find Linux Mint platform to be very robust, fast, flexible, enjoyable, easy to use, with a ton of software required for a normal user already installed and very stable.
