Install Ubuntu in Dual Mode with Windows 10


Key Points:
1. I have Windows 10 installed on the system, need to install Ubuntu (Linux) without formatting Windows 10. How ??
2. dual boot windows 10 & ubuntu.

Introduction

On the machine, I have installed Windows 10 but I also need Ubuntu. For this, go with the dual windows installation method. Now one question arises here, if we do the dual installation, Ubuntu with Windows 10 then the system would be slow???
Clearly no. Since at once, just a single OS would start possibly Ubuntu or Windows 10. It will just slow down the boot time since it gives an alternative to choose the Ubuntu or Windows 10 as beginning OS.

Step 1. Create free space for the installation of the Ubuntu. Go to This PC – Right Click – Manage – Disk Management.

In Disk Management, if you have unallocated free space available then it’s good otherwise shrink the free space from the drive for the Ubuntu OS.

Right click on the volume and choose shrink volume option.

Note: You will only get the shrink option available, if you have free space in the volume.

Next step is to specify the amount of space to shrink in MB. As shown in the below snapshot.

After specify the amount of space to shrink, click on the shrink. It will give you a unallocated space on the hard disk.

Now, windows 10 is prepared for the Ubuntu installation.

Install Ubuntu

NOTE: Before going to install Ubuntu, I would suggest you take the backup of the important documents, photos, videos or files. Because the next step is to install the Ubuntu on the available free space on the hard disk but somehow you formatted another partition by mistake then you will lose your data.

1.Now, download the Ubuntu iso image from the link provided below:
ubuntu-16.10-desktop-amd64.iso

2. Make the bootable USB stick or burn the DVD with the iso image with the utility like PowerISO or Rufus.

3. Run the system with the bootable device on the windows 10 system and you will get the prompt as shown below:

Install UbuntuInstall Ubuntu

4. In next step select language – click on continue. Next window will ask to install the updates, check on the updates (optional) – continue.

5. Select the installation type – choose the ‘something else‘ option. Because we will create manually partitions and choose where to install the Ubuntu OS.

6. In the next window, choose options carefully. If you selected another volume instead of free space volume by mistake then you will lose the data or if that was windows root volume, Windows OS would be lost. Select the free space which you have created in the windows for the Ubuntu installation. And click on ‘+’ option to create the Ubuntu partition.

7. We will create the 3 partitions i.e.
a. / (root)

8. Create partition / (root), give size in MB, choose mount point /, keep other settings unchanged and click on ok.
Now again click on free space and ‘+’ and create other partitions.
