Preloaded with Windows 8 or Windows 8.1 system uses UEFI instead of BIOS. This makes installation and dual-boot becoming conventional method before a little different. In this tutorial, we will see how to install Ubuntu 14.04 and Windows 8 / 8.1 dual-boot in UEFI mode.
This tutorial is to buy a new Dell Inspiron 7437 (fourth-generation Core i7 processor, 256GB SSD, 8GB of memory and built-in 1GB (shared memory) Intel graphics) on presentation. In order for you to successfully install UEFI under Linux and Windows dual-boot 8, I will mention all the steps you need to do. If you have completed these steps part of the steps, skip to the next step. If you have a new system, so much the better.
These steps mentioned here are also applicable to other Linux distributions Ubuntu-based, such as Linux Mint, Elementary OS and so on. Not much to say, let's look at how to enable UEFI secure boot on Windows 8 system dual-boot Linux.
Let Ubuntu 14.04 and Windows 8 dual-boot:
To install Ubuntu on a UEFI system has many prerequisites. Let's see one by one:
The first step: make a backup [optional]
Be a backup is always a good choice, the system prevents you screwed up. There are many online articles to teach you how to backup system. You can refer to this tutorial.
Step 2: Create a Ubuntu's USB startup disk / CD-ROM boot disk
The next thing you need to do is to create a USB boot disk or CD-ROM boot disk. I recommend creating a Linux OS startup disk using a USB Universal USB Installer under Windows.
The third step: to divide an Ubuntu installation partition
Suppose you have a new system, the first thing we need to do is to create a partition to install Linux. My system 256GB disk there are several partitions at the factory, but is primarily used for backup and other purposes. Primary partition is installed on Windows 8.1 C drive, about 220GB.
If you would like only one partition, which you need to split some space to Linux. If you have enough space for the size of the number of partitions, you can use them in addition to the C drive outside of any disk, as it will erase the data on the installation.
To create a partition 8 in Windows, you need to 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 divide and narrow. In my presentation, I chose C disk volumes shrink, divided into unallocated space:
After narrowing unallocated space in there good, not its partition and format. We will use it when you install Ubuntu.
Step 4: Disable the Windows Quick Launch [optional]
In order to achieve quick start, Windows 8 introduced called "quick start" new features. Although not mandatory, it is best to disable it.
Open the Control Panel> Hardware and Sound> Power Options> Select the power button> Change settings that are currently unavailable, uncheck the Enable Quick Start (recommended).
Step Five: Disable Windows Safe Boot (secure boot) 8 and 8.1 of
This is the most important step. The new Windows 8 secure boot (secure boot) was originally for security features rootkit virus, but it also prevents the dual-boot Windows and Linux. In order to achieve dual boot Windows and Linux, we must disable secure boot (secure boot) in UEFI.
Step Six: Install Ubuntu, with Windows 8 coexist
Once you disable secure boot (secure boot), that is the time to install Ubuntu. I hope you like the second step referred to as creating a USB boot disk. Insert U disk, and then start the system from the U disk.
Start from USB, you need to select the option to start from the USB in Windows. Select Options from the computer settings (such as UEFI) or click on the "Restart" while holding down the Shift key.
When you use the USB boot disk, you will see a trial (try) or install (install) Ubuntu choice here to click "Install." Also on the small screen of setup options which you can choose the language you use. Next is some checks on the hard disk space, power and network connections like. Just click Continue.
Install window you need to pay attention is to install the type (Installation Type). Select other options here (Something else):
Remember we had divided unallocated space? We will use it to create the root partition (/), swap space (Swap) and home directory (Home). Select a free (free space) and then click the plus sign (+).
It will give you the option to create a Linux partition. We are creating the root partition /. 10 to 20GB of space is enough. Select the size (Size), and then select Ext 4 file system as well as / (root mean) as a mount point (Mount point).
Click OK will return to the partition screen. Next we create the swap space (Swap). As before, once again click the plus sign (+). This time we have chosen as swap space (Swap area). Recommended swap space is twice the size of physical memory.
In the same way to create a home directory (Home). Maximum space allocated to it (actually allocated to it all the remaining space), because it is you will be used to store music, photos and location of the downloaded files.
After a good distribution of the root partition (/), swap space (Swap) and home directory (Home), click the Install Now (Install Now):
Well, you now basically won the battle and the triumphant smile exposing ~ ~ Next you will be asked to set up a user name and password, and so on. Basically you can now just click Next.
Once the installation is complete, restart your computer, you should see the purple grub welcome screen. Enjoy dual-boot Ubuntu and Windows 8 it. (Translation: grub for possible selection system is not Windows 8 option or situation fails to start, you can search using the Boot Repair tool)
I hope this guide can help you achieve your Ubuntu and Windows UEFI mode 8 dual boot. Although this article is written for Ubuntu, other Linux OS it should also help. Welcome to ask any questions and suggestions.
