If you want to install Ubuntu alongside Windows the first thing you need to do is create unallocated space on the computer hard disk, this you can do from inside Windows using Disk Management tool, then load Ubuntu and install it to the free space.
Once done, To select Ubuntu when you have Windows 10 and Linux installed simply choose it from the Grub menu, you will see this menu everytime the computer will restart.
Login into your Windows 10 system. Once done, we need to open Disk Management Console. To open Disk Management console, open run prompt (by pressing Windows Key + R or by typing ‘run’ in search bar) & type ‘diskmgmt.msc‘
Step:2) We need to free up some space from our HDD, we will do it by shrinking the volume that has some free space. Select the partition with some free space (at least 25 Gb), right click & select ‘Shrink Volume‘
Step:3) On next screen, select the amount you want to shrink and press ‘Shrink’. For our tutorial, we will be using 40 GB.
Step:4) As shown is the screenshot below, we now have 40 GB of unallocated space that will be used for Ubuntu 18.04 installation.
Step:5) Next step is to shutdown your system & insert a bootable USB or a Live DVD for Ubuntu 16 onto the system & than boot the system into the Ubuntu image.
Step:6) Once the Ubuntu image has been booted up, we should see the following options. Select ‘Install Ubuntu’.
Step:7) On next screen, we will be asked for ‘Keyboard Layout’, I am leaving it at default, modify it as per your needs & press Continue.
Step:8) On the next screen we are introduced to a little change, we have an extra option to select what apps we need to install on our system & we can either select Normal installation with all the default applications or we can also select Minimal Installation with only a web browser & some basic utilities. Select the option, you see fit & press Continue.
Step:9) On the next screen, we will select the installation type. Since we are dual booting with Window 10, we will select the option ‘something else′.
* if you see the options "Install Ubuntu Along side WIndows 10" choose it instead, as it will be easier for you.
Step:10) On this step we’ll create our custom partition layout for Ubuntu 16.04. On this guide will recommend that you create two partitions, one for
root and the other for
home accounts data and no partition for
swap (use a swap partition only if you have limited RAM resources or you use a fast SSD).
To create the first partition, the
root partition, select the free space (the shrink space from Windows created earlier) and hit on the
+ icon below. On partition settings use the following configurations and hit OK to apply changes:
Step:11) Create the
Step:12) When finished, hit the Install Now button in order to apply changes to disk and start the installation process.
A pop-up window should appear to inform you about swap space. Ignore the alert by pressing on Continue button.
Next a new pop-up window will ask you if you agree with committing changes to disk. Hit Continue to write changes to disk and the installation process will now start.
Step:13) We would be asked about our Geographical location, select your country & proceed by clicking on the Continue button, then choose the keyboard layout and click on Continue button.
Step:14) Pick up a username and password for your administrative sudo account, enter a descriptive name for your computer and hit Continue to finalize the installation.
This are all the settings required for customizing Ubuntu 16.04 installation. From here on the installation process will run automatically until it reaches the end.
Step:15) Once the installation has been completed, we will be asked to restart our system. Press on ‘Restart Now’. Also remove the installation USB / DVD from your computer before restarting the system.
Step:16) Now when the system is restarted, we will see the following boot menu first. Here we can either opt to login to Ubuntu by selecting the first option or we can also boot into Windows 10 by selecting the last option. We will boot into Ubuntu.
Step:17) Now after completing the bootup process, we will see the login screen. Select the created user & enter the password to login.
You have successfully installed Ubuntu along with Windows 10 & can now use both the operating systems without an issue.
