Step-by-Step Guide to Install Ubuntu 18.04 LTS on your Laptop or Desktop

Step 1)   Download Ubuntu 18.04 LTS ISO File

Please make sure you have the latest version of Ubuntu 18.04 LTS, If not, please download the ISO file from the link here


Since Ubuntu 18.04 LTS only comes in a 64-bit edition, so you can install it on a system that supports 64-bit architecture.

Step 2) Create a Bootable Disk

Once the ISO file is downloaded then next step is to burn the downloaded ISO image into the USB/DVD or flash drive to boot the computer from that drive.

Also make sure you change the boot sequence so that system boots using the bootable CD/DVD or flash drive.

Step 3) Boot from USB/DVD or Flash Drive

Once the system is booted using the bootable disk, you can see the following screen presented before you with options including “Try Ubuntu” and “Install Ubuntu” as shown in the image below,



Even though when you click “Try Ubuntu” you can have a sneak peek into the 18.04 LTS without installing it in your system, our goal here is to install Ubuntu 18.04 LTS in your system. So click “Install Ubuntu” to continue with the installation process.

Step 4) Choose your Keyboard layout

Choose your favorite keyboard layout and click “Continue”. By default English (US) keyboard is selected and if you want to change, you can change here and click “Continue”,


Step 5) Preparing to Install Ubuntu and other Software

In the next screen, you’ll be provided following beneath options including:

  • Type of Installation: Normal Installation or Minimal installation, If you want a minimal installation then select second option otherwise go for the Normal Installation. In my case I am doing Normal Installation
  • Download Updates While Installing Ubuntu (select this option if your system has internet connectivity during installation)
  • Install third party software for graphics and Wi-Fi hardware, MP3 and additional media formats  Select this option if your system has internet connectivity)


click on “Continue” to proceed with installation

Step 6) Select the appropriate Installation Type

Next the installer presents you with the following installation options including:

  • Erase Disk and Install Ubuntu
  • Encrypt the new Ubuntu installation for security
  • Use LVM with the new Ubuntu installation
  • Something Else


Erase Disk and Install Ubuntu – Choose this option if your system is going to have only Ubuntu and erasing anything other than that is not a problem. This ensures a fresh copy of Ubuntu 18.04 LTS is installed in your system.

Encrypt the new Ubuntu installation for security – Choose this option if you are looking for extended security for your disks as your disks will be completely encrypted. If you are beginner, then it is better not to worry about this option.

Use LVM with the new Ubuntu installation – Choose this option if you want to use LVM based file systems.

Something Else – Choose this option if you are advanced user and you want to manually create your own partitions and want to install Ubuntu along with existing OS (May be Windows or other Linux Flavor)

In this article, we will be creating our custom partitions on a hard disk of 40 GB and the following partitions are to be created:

  •     /boot           1 GB (ext4 files system)
  •     /home         18 GB (ext4 file system)
  •     /                  12 GB (ext4 file system)
  •     /var             6 GB (ext4 file system)
  •     Swap          2 GB


Now, Choose “Something Else” and Click on continue

You can see the available disk size for Ubuntu in the next window as shown below:

Now in order to create your own partitions, click on “New Partition Table



Click on Continue

Create /boot partition of size 1GB, Select the free space and then Click on the “+” symbol to create a new partition


Click on “OK”

Let’s create /home partition of size 18 GB,


In the same way create / & /var file system of size 12 GB & 6 GB respectively



Now create last partition as swap of size 2 GB,


Click on OK

Once you are done with the partition creation task , then click  on “Install Now” option to proceed with the installation



Now click on “Continue” to write all the changes to the disks

Step 7) Select Your Time zone

Choose your favorite time zone and then click on “Continue”

  1. Hi , its very good, may you please share its soft copy to down of this post or related. which can make it more when offline.

  2. Hi
    Could you please post how to do the same partitioning (the choice “something else”) with the use of LVM? Looks like the choice “Physical volume for LVM” is missing.

  3. I have two drives, I am trying to install in the second drive, the utility that sets up the file system uses part of the information from the first drive and it cannot be deleted. The trial and error process of trying to get the file system’s physical position for best performance takes too much time. I am tempted to give up on Ubuntu all-together.

  4. Thanks for the pictures, I was looking for the different partition types ! 🙂
    I am always amazed how Ubuntu install is so fast, and its USB boots on every device where Windows installer can not even boot. Thinking about reformat my own pc as well 😀

  5. This is very helpful. Tough I am trying to install it into SD Card and boot from there but my Lenovo G410 laptop bios seems to only recognize USB not and SDC. Anyone tried to install it in SDC? If not then I will just install and boot from USB then. I really wanted to start using Xubuntu on my laptop. Dual boot Win10 and Xubuntu. Help needed.

    Lenovo G410 – set to Legacy to boot from USB
    SanDisk SDC 16GB – wanted to boot and install it here but SDC not recognized, do I need to have to use software to boot from here? what settings do I need?
    Xubuntu ISO
    YUMI – used as multiboot app

    Thanks guys

  6. installing from cd hope the /boot is ok as i have efi here ??
    this guide was easy to follow tho your screenshots look dated are they from an older version?

  7. Good info! Thx for that! Can you give more information please?
    Why you use
    /boot 1 GB (ext4 files system)
    /home 18 GB (ext4 file system)
    / 12 GB (ext4 file system)
    /var 6 GB (ext4 file system)
    /Swap 2 GB”??
    A lot of tutorial say use 3 partitions:

    What about SSD?? Does it need swap (why?, How much?)??
    It’s wery interesting question for me and I hope for other people too. Please, give me the answer if you know.

  8. @Mr.Anderson,
    separate root partition is necessary if you want to encrypt your disk.
    Root partition as ext4 is not the best idea, I would stick with ext2

    • Hi Chris,

      You assigned most of disk space to /home file system if you are planning to use it as desktop workstation, because all the user’s data will be saved under /home partition in their respective home directory.

  9. Hi Pradeep,
    Thank you for this helpful post, it is really very helpful. Could you please guide me that I want to partition my whole 320 GB harddisk, so how much spaces should I allocate to the above mentioned partitions?

  10. Cannot instal. Step 6 never appears to my screen, so I cannot choose any options and the Program stops, Only the preview Works. What to do? Processor is ok, core 2, terabyte room in hard drive..??

  11. burned a dvd from a windows 10 laptop and did an install on a windows 7 laptop. Windows 7 would never burn the dvd. The install never asked to run trial or install, no language screen, no keyboard layout screen. no installation type, no partitioning. It just did an install on it’s own parameters that I didn’t choose, Ubuntu did launch, mouse works, keyboard doesn’t. Small wonder. What am i missing?

  12. My laptop told me to disable iRST, I have 1 TB SSD and no HDD. can I install ubuntu? or is it not possible/safe to create partitions in SSD?
