Assumption is that Windows 10 already installed.

To start off, you need to create a free partition on your hard drive.

This is the partition where Linux will be installed during the installation process.

To achieve this, you will invoke the disk management utility as shown:

Press Windows Key + R to launch the Run dialogue. Next, type diskmgmt.msc and hit ENTER.

This launches the disk management window displaying all the drives existing on your Windows system.

Next, you need to create a free space for Linux installation.

To do this, you need to shrink a partition from one of the volumes and create a new unallocated partition.

For example create a 30 GB partition from Volume D.

To shrink a volume, right-click on it and select the ‘shrink’ option

In the pop-up dialogue, define the size that you want to shrink your space. Remember, this will be the disk space on which Linux will be installed. In the example select 30000MB ( Approximately 30 GB). Once done, click on ‘Shrink’.

After the shrinking operation completes, you should have an unallocated partition as shown.

Perfect! We are now good to go and ready to begin the installation process.

With the free partition already created, plug in your bootable USB drive or insert the DVD installation medium in your PC and reboot your system.

Be sure to make changes to the boot order in the BIOS set up by pressing the function keys (usually, F9, F10 or F12 depending on the vendor).

This is crucial so that the PC boots into your installation medium.

Saves the BIOS settings and reboot.

A new grub menu will be displayed.

Click on ‘Graphical install’

Continue going through all install options…

You will then be prompted whether to install the grub bootloader on Master Boot Record (MBR). Click Yes and click Continue.

Next, select the hard drive on which you want to install grub and click Continue. Most likely /dev/sda.

Finally, the installation will complete, Go ahead and click on the ‘Continue’ button.

You should now have a grub menu with both Windows and Linux listed.

To boot to Linux, scroll and click on Linux. Thereafter, you will be prompted with a login screen. Enter your details and hit ENTER.
