Installing Ubuntu on a Pre-Installed Windows 10 with UEFI


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 16.04 in dual-boot with a Microsoft Operating System on machines that come pre-installed with Windows 10.

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

This guide assumes that you’re 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, 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...

General UEFI install Info (not for Macs)
New installs must use only current versions of Installer as old ones had major bug that erased all partitions even if it says it only over writes Ubuntu partition. Newest 16.04 or current 14.04 are fine, but not older versions of 14.04.
If reinstalling Ubuntu only use Something Else (links to examples below).

Backups are very important, see backup section below.

UEFI is now a bit more complex than the old BIOS install as it includes both UEFI and BIOS as options. You must choose in UEFI and choose how you boot installs. Various settings in UEFI/BIOS may be required to enable correct boot mode. You do always want to boot in UEFI mode, but may not need nor want secure boot mode of UEFI.
Install instructions for dual booting in UEFI apply with any current version of Windows in UEFI mode & Ubuntu in UEFI mode. Very minor differences with newer Windows (same settings required) and Ubuntu...

The Unified Extensible Firmware Interface (UEFI) was designed to initialize the hardware faster than the legacy BIOS and help the OS to boot in normal conditions. Starting with Windows Vista, Microsoft supports EFI installation of Windows. This means that we can install Windows Vista, Windows 7, Windows 8 and 8.1 or Windows 10 using the UEFI mode.

Beginning with Windows 8, UEFI was added both, for 32-bit and 64-bit editions. With UEFI, the booting speed of the operating system will increase significantly. Do you want to find out how to install Windows correctly in UEFI mode? Find below a helpful guide, that will help you install Windows 10 in UEFI mode.

More and more disgruntled Windows 8.1 Metro users and Windows 10 users email us about dual booting a Linux operating system alongside their factory installed Windows® installation. As a person who has designed systems for longer than most people have been alive, I can readily understand your frustration. When I’m designing a system there is always the issue of where to place a simple thing like the taskbar. That placement is important but not a game changer in most cases. I look at it as if it were a car being driven either on the left or right side of the car. If one can drive, more than likely, they will be able to drive on either side without too much difficulty. What Microsoft has managed to do is to put the steering wheel in the trunk. With that said - what you need to do first is to get back some familiarity to your computing experience in Windows, especially Windows 8. Let’s put the steering wheel back where it belongs first.

While in Windows 8 head on over to...

Note: this how-to isn't meant for installing Linux Mint or Ubuntu on a computer with UEFI in full UEFI mode, but only for repairing bootloader Grub of an existing installation on such a computer. For installing Ubuntu or Linux Mint on such a computer you can use this other how-to *click*.

A modern computer with Windows 8.x or 10 has EFI or UEFI, that's running in full UEFI mode. On such a computer you might, after a successful installation of Ubuntu or Linux Mint, suddenly lose the possibility to boot Ubuntu or Linux Mint.

For example this might happen because you've reset your UEFI to its defaults, or because you've upgraded your UEFI to a later version.

Thankfully this problem is not difficult to solve. Provided that you apply the how-to below, with exact precision.

Note: this how-to is only fit for modern motherboards that run on UEFI in full UEFI mode. This is usually the case for computers that were sold with a...

Ubuntu MATE 15.04 DVD should show you a menu like that one:

* Try Ubuntu MATE without installing Install Ubuntu MATE OEM install (for manufactures) Check disc for defects

Now you press "e" ! You should see another menu like this one:

setparams "Try Ubuntu MATE without installing" set gfxpayload=keep linux /casper/vmlinux.efi file=/cdrom/preseed/ubuntu-mate.seed boot=casper quiet splash --- initrd /casper/initrd.lz

Now you replace "quiet splash" with other boot options. e.g.

setparams "Try Ubuntu MATE without installing" set gfxpayload=keep linux /casper/vmlinux.efi file=/cdrom/preseed/ubuntu-mate.seed boot=casper noapic --- initrd /casper/initrd.lz

After that, press F10 to continue. That's it. It is really easy, isn't it...

Introduction :

At this point in time (2013 Jan), it is hard to find good, detailed information on how to install Linux on the new Window 8 PC's that are equipped with 'new BIOS' versions that have the PC initialized in UEFI boot mode.

The new-circa-2013 UEFI boot mode can make installing Linux a pain ...

if only because of all the reading and (re)searching one has to do to get information on how to handle this new boot mode.

NOTE: This set of notes is aimed at running Linux IN PLACE OF Windows 8 on a computer. If you are interested in a DUAL-BOOT of Linux and Windows on a computer, this page probably does not have a lot of useful information for you. If you are interested in dual-boot, this YouTube video, entitled 'Dualboot Windows 8 with Linux Mint 14 Nadia' and posted by 'Avoiderrors' on 2012dec05, may be of more use to you. He also posted a video of installing Linux Mint 13 for dual boot with Windows 8. (However, he does not show doing anything...

When the installation is complete, I am prompted to reboot (or continue working with the Live system).

On both of my UEFI systems, I got the same surprise with Ubuntu that I had already gotten with openSuSE and Fedora — reboot didn't bring up Ubuntu, it still brought up whatever was booted before I did any of this (in most cases, this will be Windows 8).

Now, there may be other systems, from other manufacturers that do in fact get UEFI boot parameters set, stored and stable properly so that they boot Ubuntu, but that hasn't been my experience. Oh, and there is another even bigger problem...

If you still have Secure Boot enabled, which was the purpose of this exercise, then when you finally do try to boot Ubuntu (probably by pressing Boot Select), you are going to be very surprised to find that it doesn't boot.


At least, it didn't for me, on either one of my systems. What the heck is that about?

Back in 2011, many Linux fans were furious at the prospect that machines capable of running Windows 8 might lock them out of the ability to install Linux distributions on their own computers. The discussion was spurred by the fact that the BIOS firmware on motherboards would require UEFI compatibility for every system installed on the machine.

As a resolution, Microsoft mandated that manufacturers give users an “off switch” for UEFI Secure Boot. Fast forward to 2015, and the rage began once again when Microsoft announced that Windows 10 will not require manufacturers to include an option to turn off UEFI. What does this mean? Is Linux being phased out by design?

As I’ve said above, Linux users are understandably concerned about Windows 10’s eventual prospect. Until 2015, manufacturers of BIOS chips and motherboards were required to allow users to turn off UEFI checking so that they can run Linux on their machines without any disturbance. The release of Windows 10...

I've tried to install elementary OS alongside Windows 10 in a UEFI machine. I first did it with Secure Boot enabled, using the "something more" option. I configured the root and swap partitions as I always do. But the strange thing is, when the installation ended and the machine was rebooted, Grub did not showed up and Windows was loaded instead. Then I retried disabling Secure Boot, and the same thing happened, so I loaded the live cd and reinstalled and updated grub from a chrooted partition as seen here: same result. I get the same results with Ubuntu 15.10.

Can someone point me in the rigth direction? What am I missing here?

My machine is an Alienware X51 R3 with a Samsung’s PM851 M.2 SSD and Windows 10 installed. I have previously succeded double-booting Windows 10 + Elementary OS in an Alienware X51 R2 and a Samsung EVO 840...

Windows, move; make some room for Linux

First we will start by making some space for our Linux OS. For that purpose search for “Create and Format Disk Partitions” in the start menu or directly in the metro view.

[If your computer came with Windows pre-installed, you will most probably have only one partition “C:\”. I heavily recommend keeping the system files and your data on different partition so in case of Windows corruption and failure you won’t risk losing your data. You can simply reinstall Windows.]

Once you are in the disk management window, right click on the partition you wish to resize and select “Shrink Volume”:

In the popup window select the amount of disk space that you wish to shrink. Make sure to give at least 10 GB of disk space for your Linux distro.

Shrink as much space as you need:

If you are using Ubuntu 16.04+, many issues are now solved, so there is no need to follow this guide except if you are using any Ubuntu version older than 15.04. Depending on the version you are using (12.04, 14.04, 14.10) you might need all or some of the steps provided in this answer, or if you want to debug the installation process.

If however, you are using 16.04+, rejoice!, in all tests I have done with 16.04+ there was no need to do any of the steps mentioned here, so enjoy Ubuntu in all of it's booting glory!.

For the rest, before explaining the steps to do it, I want to be clear that I have tried many ways of installing Ubuntu with versions older than 15.04 (Or any other distro for that matter) from within Windows 8 or Windows 10. No luck. Microsoft Windows really created a big mess for all Linux distributions. If you have a pre-installed Windows 8 system, you will probably never be able to install Ubuntu or any other OS in the normal (LiveCD/LiveUSB) or Wubi...

First, unallocated space in a partitioning tool like GParted is different from unused space on a partition. Unallocated space in the partition table is unusable from an OS unless and until a partition is created in that space, or until an existing partition is resized to cover that space. This is because a partition is sort of like a room number in a hotel; without it, although the space exists on the disk(/hotel), the OS(/guest) can't locate it.

Second, you should never create a partition in Windows that you intend to be used by Linux. You seem to have gotten lucky and didn't do any damage, but many people who do what you did end up having to use third-party utilities to fix the damage -- when asked to create more than four partitions, Windows will, unbidden, convert from a standard partitioning setup to a Logical Disk Manager (LDM), aka dynamic disks, setup. You can't install Linux to such a disk, so you've got to undo this operation, which of course can't be done with the...

Note: As of right now, Ubuntu 15.04 will BOOT on a bay trail tablet, but it will not install correctly.

My guide is based mostly on this one, but with minor adjustments, and easier to follow instructions. This guide is tested and working on the Winbook Tw100 Windows 8 tablet (by Microcenter).

You may require:

USB OTG (on the go) cable, for connecting the USB drive/keyboard/mouse A 4GB or more USB flash drive Any downloads mentioned below You will need to disable Secure Boot and change the boot order in your tablet's BIOS settings

Problem 1: Booting a 64-bit OS with a 32-bit UEFI BIOS on a 64-bit CPU (it's like a jigsaw puzzle)

Download the latest Ubuntu 14.10 (64-bit) ISO file Download Universal USB Installer Use Universal USB Installer to create a bootable Ubuntu 14.10 USB drive Download this bootia32.efi file from GitHub Place the bootia32.efi file you just downloaded into the EFI/BOOT/ folder of the bootable Ubuntu 14.10 USB drive you just created...

You should defragment your Windows partition, as far as I know Windows comes with a tool for that.

Once defragmentation is complete you have to perform a "full shutdown" in Windows, as by default it does like a hibernation when shutting down. To do that search for cmd in Windows Search and it will point you to the command line prompt, start it and execute the following command:

shutdown /s /t 0

Now you have to start a Ubuntu live session by booting a Live-USB and choosing the option: Explore Ubuntu without installing.

When the desktop loads up, start GParted and you should see the EFI partition at the start of the partition table followed by your drive C:\ partition, click on the C:\ partition and re-size it to make room for Ubuntu partition. Click on the "Apply" button of GParted and wait until it completes the operations.

Now start the Ubuntu Installator, when it prompts you for the installation type you should choose Something Else, the last...
