Are you one among those who are facing problems in understanding and following the already published guides from popular websites that discusses on the process to dual boot Ubuntu alongside Windows? In that case, this guide is absolutely for you. Frankly speaking, I have no experience prior in dealing with Ubuntu or installing it on my machine. I just tried a few days back and I’m so very much confused with the guides available.

Luckily I found a guy who helped me personally to get the work done. I’m a newbie and so are you. For us, the much complex guides will be of no use and trust me, even if you do try, there are greater possibilities that you might end up screwing your data.

So, considering the fact that there might be many other people like me, who are having a hard time trying to dual boot Ubuntu alongside Windows, I have decided to write this guide for the same, in a much simpler manner. You need not ask for anyone else’s suggestions if you’re following this guide.

So, with no further delay, let us start with the installation procedure to dual boot Ubuntu alongside Windows.

Procedure To Dual Boot Ubuntu Alongside Windows

Considering you have Windows on your machine, even before you download Ubuntu Software, you need to have a free unallocated space of around 30GB (more than needed) on your hard drive.

Create Unallocated Space In HDD Using Windows Disk Management

Follow the below steps to create a free unallocated partition.

Step 1: If you’re on Windows 7, Right click on “My Computer” and click on “Manage“. If you’re on Windows 8/8.1/10, go to “File Explorer“, Right Click on “This PC” and click on “Manage“.

Step 2: Now, click on “Disk Management“. Your partitions will be loaded and choose the partition for which you want to split the volume. You can see a window like the one in the image below.

Suppose you have a drive that has 250GB of hard disk space and you want around 30GB separated from it. In that case, select the partition with 250GB, Right Click on it and click on “Shrink Volume“. In the dialogue box, enter the space you need in MB. You can simply enter 30000 MB (it is not exactly 30GB, but there’s no harm in allocating this way). You’ll get around 29.2GB if you enter 30000 MB to shrink.

After shrinking, do not format the partition. Leave it unallocated. In case if you had already formatted the partition, just Right Click on the partition and click on “Delete“. It’ll then make the space unallocated.

You’re now done with creating unallocated space which will be used for installing Ubuntu later on. Now, there’s one more step you have to do being on Windows OS. You must download Ubuntu OS and create a bootable flash drive.

Download Ubuntu OS & Create Bootable Flash Drive

Follow the below steps to create a bootable flash drive to carry on the process to dual boot Ubuntu alongside Windows OS.

Step 1: Download Ubuntu OS. You can either download Ubuntu 14.04.3 LTS or download Ubuntu 15.10. Also make sure to choose 64-Bit version. In case if you have RAM lesser than 4GB, go with 32-Bit version. A .iso file of Ubuntu OS will be downloaded.

Step-2: Once the .iso file of Ubuntu OS is downloaded, you need to create a bootable flash drive for installing Ubuntu alongside Windows. Download the file below to create a bootable flash drive.

Step-3: Once the file is downloaded, open it. You’ll have to choose “Ubuntu” from the drop down menu under “Step 1” shown in the software. In “Step 2“, select the .iso file you have downloaded by clicking on “Browse“. Under “Step 3“, select the flash drive you inserted to your machine. Finally, click on “Create” and wait for some time.

Once the process is complete, you have successfully created a bootable flash drive for installing Ubuntu.

However, to proceed further with the installation, you need to enter into the boot menu. Restart your Laptop/PC and press F10/F2/F12/ESC. The button varies for different models, variants and companies. You can check the key of your laptop here. You’ll have to press the key immediately once you see the start-up screen.

Once you enter the boot menu, you can see your USB Flash Drive to boot from. In case if you don’t, enter into the settings and move on to “Advanced” option. You can see “Fast BIOS Mode” enabled by default there. Click on it and select “Disable“. Now click on “Save and Exit.” That’ll reboot the system.

Click on the boot key again to enter into the boot menu. Now, you can see your Flash Drive as an option to select. Select it and press Enter.

Installation Procedure To Dual Boot Ubuntu Alongside Windows

Once you are successful in booting from USB flash drive that has the Ubuntu OS in it, you can see a screen with options like, “Try Ubuntu”, “Install Ubuntu“.

You can click on “Install Ubuntu” now. You’ll then be taken to the installation screen. Follow the below steps to continue the procedure to dual boot Ubuntu alongside Windows.

Step 1: Choose your language and click on “Continue.”

Step 2: Considering that you chose English as your language, in the next step, you’ll be asked to choose if or not to download packages while installing Ubuntu. For better results, your Laptop must be connected to the internet, should have at least 7GB space (which we do have) and connected to a power source.

Check both that says “Download updates while installing” and “Install third party software” and click on “Continue“.

Step 3: Now is the most important part. Since we are trying to dual boot Ubuntu alongside Windows, choose the first option that says “Install Ubuntu alongside Windows Boot Manager” and click on “Install Now“.

Since we have already made available of the unallocated partition space, you don’t need to manage the disk hierarchies. Our process automatically allocates space for ‘/’ (root) and swap area. This will make the work easier for the newbies.

In case if you chose “Something Else”, god save you. It’ll be hard for you to understand if you’re a newbie like me.

Step 4: You’ll get a pop up window with two options “Go Back” and “Continue“. Click on “Continue“.

Step 5: Your location will be automatically detected and in case if there’s any mistake, choose your location and click on “Continue”.

Step 6: In the next step, you can choose your “Keyboard Layout“. Select “English (US)” and click on “Continue“.

Step 7: Enter your “Name” and “Password” and click on “Continue”.

And that’s it. The installation procedure will be automated from here and all you need to do is, sit back and relax. You’ll be seeing a screen similar to the below image.

Final Word

After the procedure is complete, you’ll be asked to reboot your system. Click on “Reboot” and once the system is restarted, you will see options to select Ubuntu or Windows. Select Windows and check your files in the same state you left them before starting the installation procedure to dual boot Ubuntu alongside Windows. None of your files are deleted during the installation. From now on, you can head to Ubuntu or Windows on the start up of the system each and every time.
