Ubuntu 16.10 released with a support of 9 months until July 2017 and Ubuntu 16.04 has been released in wild by Canonical with a life circle of 5 years support.
This tutorial will guide you on how you can perform the installation of Ubuntu 16.10 and Ubuntu 16.04 in dual-boot with a Microsoft Operating System on machines that come pre-installed with Windows 10.

For fresh Ubuntu 16.04/16.10 installation, read our article about Ubuntu 16.04 Desktop Installation Guide and Ubuntu 16.10 Installation Guide

This guide assumes that your machine comes pre-installed with Windows 10 OS or an older version of Microsoft Windows, such as Windows 8.1 or 8.
In case your hardware uses UEFI then you should modify the EFI settings and disable Secure Boot feature.
If your computer has no other Operating System already installed and you plan to use a Windows variant alongside Ubuntu 16.04/16.10, you should first install Microsoft Windows and then proceed with Ubuntu 16.04 installation.
In this particular case, on Windows installation steps, when formatting the hard disk, you should allocate a free space on the disk with at least 20 GB in size in order use it later as a partition for Ubuntu installation.

Requirements

Download Ubuntu 16.04 and Ubuntu 16.10 ISO Image as per your system architecture using following link:

Step 1: Prepare Windows Machine for Dual-Boot

1. The first thing you need to take care is to create a free space on the computer hard disk in case the system is installed on a single partition.
Login to your Windows machine with an administrative account and right click on the Start Menu -> Command Prompt (Admin) in order to enter Windows Command Line.

2. Once in CLI, type diskmgmt.msc on prompt and the Disk Management utility should open. From here, right click on C: partition and select Shrink Volume in order to resize the partition.

C:\Windows\system32\>diskmgmt.msc

Shrink Volume to Resize Partition

3. On Shrink C: enter a value on space to shrink in MB (use at least 20000 MB depending on the C: partition size) and hit Shrink to start partition resize as illustrated below (the value of space shrink from below image is lower and only used for demonstration purposes).
Once the space has been resized you will see a new unallocated space on the hard drive. Leave it as default and reboot the computer in order to proceed with Ubuntu 16.04 installation.

Step 2: Install Ubuntu 16.04 with Windows Dual-Boot

4. Now it’s time to install Ubuntu 16.04. Go the download link from the topic description and grab Ubuntu Desktop 16.04 ISO image.
Burn the image to a DVD or create a bootable USB stick using a utility such as Universal USB Installer (BIOS compatible) or Rufus (UEFI compatible).
Place the USB stick or DVD in the appropriate drive, reboot the machine and instruct the BIOS/UEFI to boot-up from the DVD/USB by pressing a special function key (usually F12, F10 or F2 depending on the vendor specifications).
Once the media boot-up a new grub screen should appear on your monitor. From the menu select Install Ubuntu and hit Enter to continue.

5. After the boot media finishes loading into RAM you will end-up with a completely functional Ubuntu system running in live-mode.
On the Launcher hit on the second icon from top, Install Ubuntu 16.04 LTS, and the installer utility will start. Choose the language you wish to perform the installation and click on Continue button to proceed further.

6. Next, leave both options from Preparing to Install Ubuntu unchecked and hit on Continue button again.

7. Now it’s time to select an Installation Type. You can choose to Install Ubuntu alongside Windows Boot Manager, option that will automatically take care of all the partition steps.
Use this option if you don’t require personalized partition scheme. In case you want a custom partition layout, check the Something else option and hit on Continue button to proceed further.
The option Erase disk and install Ubuntu should be avoided on dual-boot because is potentially dangerous and will wipe out your disk.

Select Ubuntu 16.04 Installation Type

8. 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:

Size = at least 20000 MB
Type for the new partition = Primary
Location for the new partition = Beginning
Use as = EXT4 journaling file system
Mount point = /

Create Root Partition for Ubuntu 16.04

Create the home partition using the same steps as above. Use all the available free space left for home partition size. The partition settings should look like this:

Size = all remaining free space
Type for the new partition = Primary
Location for the new partition = Beginning
Use as = EXT4 journaling file system
Mount point = /home

9. 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.
