This guide will walk you through the steps to install Linux Mint 21 Cinnamon edition, but the steps below also work for Mate and XFCE editions.

Before you proceed, ensure that you have a 4 GB USB drive for the installation medium and a stable broadband internet connection to download the ISO image.

Step 1: Download Linux Mint 21 ISO Images

First of all, you need to download the ISO image from the links below:

Once you downloaded the preferred desktop edition, make sure to verify the ISO image by generating the SHS256 sum as shown:

$ sha256sum -b linuxmint-21-cinnamon-64bit.iso [for Cinnamon]
 $ sha256sum -b linuxmint-21-mate-64bit.iso [for Mate]
 $ sha256sum -b linuxmint-21-xfce-64bit.iso [for XFCE]
Verify Linux Mint ISO

Compare it with the sum presented in the sha256sum.txt which you can download from the ISO download page as highlighted in the following screenshot.

  1. I’m a newbie Linux user. I loaded Linux mint xfce 18.3 on my tablet some time ago. Now I want to remove 18.3 from my laptop and load Linux mint xfce 19.2 in its place, and have acquired a live bootable disk for that purpose.

    How do I make a backup copy of what’s loaded now and can I use a USB for storing the backup?

    Should I choose to remove everything from the drive after a backup copy is made for a clean install?


    • @Jack,

      Better you can take backup of important files to your USB drive, and do a clean fresh install of Linux Mint…

      • Ok, but how do I select the files and move them to a USB drive?

        With a clean installation do I still have to make manual partitions or can I let the device make the partitions automatically?

  2. Everything was ok, after reboot I get the message “Booting freezing on the screen, nothing happens”.

  3. Hello, I am having issues going back to my Linux screen from the command page. It shows something like Linux Mint 19.2 Tina Abdulkareem-X551CAP TTYL and then password and login details required. I don’t know if I can share my screen so as to understand what the problems…

  4. Hi, Currently running Mint 17 Qiana for the past year, on an 80 GB root internal drive, and two other drives, a 160 GB and a 1TB drive, both using USB the 80GB drive is telling me it is full, yet the directories say it is only “half” full machine is sluggish and acting strangely…(I can’t save files to desktop…)

    So, I purchased a 2 TB drive, and wish to install Mint 18.3 Sarah, on that, keeping the two USB data drives. Are there any pitfalls I should watch for? I would also like to name the partitions rather than
    have a 17 digit Alpha- Numeric naming protocol on my 1TB drive, and a 9 digit Alpha- Numeric for the 160GB as it is currently (by default).

    This will be my 2nd Linux installation. Thank You.

  5. Hi, i installed Linux Mint with following partition /(120GB), swap(4gb) and /home (remained capacity approximately 376 Gb). my HDD is 500GB. every thing is going well. but I have a drive on my computer beside filesystem (which is my root) when I want to open I face to this error “unable to mount location, can’t mount file”.

    I don’t know about this drive is that /root drive? why I can’t mount it.I want another drive to save my files and other stuff except /root and /home partition.

    • @morteza

      You need to mount the drive partition manually and add a mount entry in /etc/inittab so it is auto mounted at boot time. For more info, check out the mount utility man page.

    • Just follow the steps used in the guide, it is done the same way the partitions here have been created. C=/ (root)partition in Linux and likewise create another partition as D.

  6. What happens if you skip adding the partitions during installation? I have to ask since I am new to linux.
