Steps to Install Windows 10 on existing Ubuntu 16.04

Installing Ubuntu after Windows is easy and strait forward process. But to install Windows after Ubuntu is a bit tricky and not recommended. But you still have to do it sometimes.

So, here are the steps to install Windows 10 when you have Ubuntu 16.04 already installed. And you want to run both together.

1. Prepare partition for Windows Installation in Ubuntu 16.04

  •  To install Windows 10, it is mandatory to have Primary NTFS partition created on Ubuntu for Windows.
  • Create Primary NTFS partition for Windows installation using gParted OR Disk Utility command line tools. If you have existing logical/extended partitions in which you want to install windows, then you need to delete that partition and create new Primary Partition. (NOTE: All data in the existing logical/extended partition will be erased. Because you want Windows there.)

2. Install Windows 10

  • Start Windows Installation from bootable DVD/USB stick.
  • Once you provide Windows Activation Key, Choose “Custom Installation“.
  • Select the NTFS Primary Partition(we have just created in Ubuntu 16.04)
  • After successful installation the Windows bootloader replaces the grub. So, when Windows boots, you won’t see the grub menu to choose Ubuntu. So, Next you need to install grub again for Ubuntu.

3. Install Grub for Ubuntu

  • To install and fix grub, you need LiveCD or LiveUSB of Ubuntu.
  • Once you load Live Ubuntu, Open Terminal and fire following commands to install boot-repair and let it fix the Grub.
    sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
    sudo apt-get install -y boot-repair && boot-repair
    
  • After installation, boot-repair will get automatically launched.
  • Make sure to select “recommended repair” option to repair grub. Reboot.
  • You will now have a Grub menu on boot, where you can choose from Ubuntu, memtest, and Windows 10
