Written by Prajjwal Rajput

Today I’m gonna show you, how to dual boot Deepin OS 15.4 and Windows 7/8.1 or Windows 10 in UEFI firmware BIOS devices. Why today I’m sharing this? Because most of the manufacturers are using the UEFI BIOS instead of old one Legacy firmware. And it is not easy to install an OS in UEFI firmware since you’re using GPT partition scheme for your HDD.

Deepin OS is the Chinese Linux distribution which was formerly based on the Ubuntu until version 15 released in late 2015, now Deepin 15.4 has been released and it is based on the Debian. Deepin OS is a beautiful and best Linux Distro but the company claims to provide the best and beautiful operating system, elegant user interface. It has its own DE(Desktop Environment) called DDE or Deepin Desktop Environment which is based on the Qt 5 toolkit.

I’m not going to show you the history of Deepin OS here I’ve collected some information from the Distrowatch website about Deepin OS and you can get to know about this distribution from the table given below.

Now back to the topic of the post i.e. dual booting Deepin OS 15.4 with Windows 10 in UEFI firmware device.

In this tutorial, We’re assuming that you’ve already installed the Windows 10 Creators Update or any update and you just need to make a partition of at-least 34GB or you can make larger for storing more files.

In this article, we make easier for you to install Deepin OS 15.4 alongside Windows 10 by dividing sections, this guide is especially for noob if you’ve already dual booted your PC with another distribution like dual boot with Ubuntu then you can simply do this and it is easy for you, but for noobs here I’m for helping them.

Download Required:

Step 1: Make Bootable USB Flash Drive

  4. Now it will prompt to show that ISOHybrid image detected Simply select Write in ISO image mode

    Click OK

Once the Process is finished, means your 1st step is completed now move to the second step.

Step 2: Make Partition For Dual-Boot Deepin OS

1. Ensure that your system should have sufficient space to install the Deepin OS you should have at-least 34GB space on any partition and you have to shrink 34 GB to make a new unallocated partition, you can shrink more space from your partition if you need to install more application on Deepin OS or store images, music, and other files.

4. Then Partition Table should display, In this, you can create your custom partition layout for Deepin OS 15.4, Generally while Dual-boot any Linux distro with Windows we recommend that you create three partitions listed below

  • root/” partition for your root folder
  • home partition for accounts data like Downloads, Documents, Music, Pictures….etc
  • swap partition if you have 4 GB or less RAM on your computer or you are using an SSD.

root Partition

To create the root partition select the Freespace partition (that we’ve created shrink space from C: drive in Windows) and click on New Partition.

Create New partitions

On Add Partition Settings use the following root Partition configurations and hit OK to apply changes:

  • Type: Primary
  • Size: at least 10240 MB
  • Align: Begin
  • FileSystem: ext4
  • Mount: /

root partition

home Partition

Now follow the same process for creating the home partition, you can add use more Size for this partition but here I’m going to make it of 20480 MB. Use the following home partition configurations and hit OK to apply changes:

  • Type: Primary
  • Size: at least 20480 MB
  • Align: Begin
  • FileSystem: ext4
  • Mount: /home

home partition

swap Partition

Now the final partition will be swap partition ( if you have less RAM) then follow this step otherwise skip this. Use the following swap partition configurations and hit OK to apply changes:

  • Type: Primary
  • Size: at least 4096 MB
  • Align: Begin
  • FileSystem: ext4
  • Mount: swap

swap partition

5. All 3 partitions have been created, now ensure that UEFI option below is checked and click on the root “/” partition then hit yellow Install, in order to apply changes to disk and proceeds the installation process.

A pop-up window will appear to inform you that the partition will be formatted if you continue the installation. Ignore this and click OK in order to start Installation.

Proceed to Install!

Now, wait until the installation process is done and. Once the Installation Succeed! hit the Reboot Now button and your computer will reboot

installation succeeded!

Your computer will reboot into the black screen Grub menu where it asks you to choose your operating System between Deepin and Windows 10 or wait 10 seconds it will open Deepin because Deepin OS is designated as default OS to boot from.

After Deepin OS boot finishes enter your password to login into your Deepin computer and you’ll see a beautiful Desktop and elegant UI of Deepin OS which is really awesome 🙂
