Install Ubuntu 14.04 and Windows 8/8. 1 In UEFI Mode

UEFI is used to replace BIOS in Windows 8 or 8.1 pre-installed systems. This makes the installation of Dual-boot a little different from the conventional method. In this tutorial, we will see how to install Ubuntu 14.04 and Windows 8/8. 1 In UEFI mode.

This tutorial is demonstrated on a new Dell lingyue 7437 (core i7 fourth-generation processor, 256 gb ssd, 8 GB memory and built-in 1 GB (shared memory) Intel graphics card. To enable you to successfully install Dual Boot for Linux and Windows 8 under UEFI, I will mention all the steps you need to do. If you have completed some of these steps, go directly to the next step. It would be better if you have a brand new system.

The steps mentioned here also apply to other Ubuntu-based Linux distributions, such as Linux Mint and Elementary OS. Not to mention, let's take a look at how to double-boot Linux on a Windows 8 system with UEFI enabled.

Enable Both Ubuntu 14.04 and Windows 8:

There are many prerequisites for installing Ubuntu on a UEFI system. Let's take a look:

Step 1: make a backup [Optional]

Making a backup is always a good option to prevent you from messing up the system. There are many articles on the Internet to teach you how to back up the system. You can refer to this tutorial.

Step 2: Create a USB boot disk/CD boot disk for Ubuntu

The next thing you need to do is create a USB boot disk or a CD boot disk. In Windows, we recommend that you use the Universal USB Installer to create a USB boot disk for Linux OS.

Step 3: divide an installation partition for Ubuntu

Suppose you have a brand new system. The first thing we need to do is create a partition to install Linux. The GB disk in my system has several partitions when it leaves the factory, but it is mainly used for backup and other purposes. The primary partition is a C disk with Windows 8.1 installed, which is about 220 GB.

If you have only one partition like this, you need to split up some space for Linux. If you have a number of partitions with sufficient space, you can use any disks except drive C, because the data in these disks will be erased during installation.

To create a partition in Windows 8, you must use the disk management tool. You can search for 'disk' in the control panel to find the disk management tool.

In the disk management tool, right-click the volume you want to split and zoom out. In my demo, I selected the volume of drive C to narrow down and divided the unallocated space:

The unallocated space that appears after the scale-out is put there, so you don't have to partition and format it. We will use it when installing Ubuntu.

Step 4: Disable Quick Start in Windows [Optional]

To enable quick start, Windows 8 introduces a new feature called "Quick Start. Although it is not mandatory, it is best to disable it.

Open Control Panel> hardware and sound> power options> select Power Button Function> change current unavailable settings, deselect enable quick start (recommended ).

Step 5: Disable secure boot for Windows 8 and 8.1)

This is the most important step. The new secure boot (secure boot) in Windows 8 was originally designed to defend against the rootkit virus, but it also blocks the dual-boot of Windows and Linux. To enable Dual boot for Windows and Linux, We must disable secure boot in UEFI ).
