The purpose of this Instructable is to set up your computer to dual-boot Windows 7 and Ubuntu Linux. Dual-booting is a technique which allows a single physical computer to run two or more operating systems (OSes). This is useful for experimenting with new OSes without putting all your eggs in one basket.

Step 1: Getting Prepared

Prerequisites:
1. A PC running Windows 7, with at least 30 GB of free hard-drive space.
2. A CD/DVD burner and blank CD/ DVD or a USB drive with a capacity of 1GB or more
3. An external Harddrive big enough to backup your Windows installation
4. Administrative access to the PC
5. Internet Connectivity

Most PCs sold in the last three years should meet the criteria for number 1. To confirm what version of Windows you are running, go to My Computer and click on “System properties.” The listed version should be Windows 7.

From that same screen, you should see how much free space you have left, which is underneath the blue bar for each disk. In the example image, there is "8.49 GB free of 55.7GB".

NOTE:The 8.49GB shown in the example is not enough space for most people. While you can install Ubuntu to a partition this size, you will typically want more space store documents and applications. 20GB is probably the minimum size you would want.
<p>does it have to be windows 7 because i did this on vista.</p>

<p>after installing ubuntu i chose to boot up windows to make sure i didnt stuff anything up but when i chose windowd it showed the loading windows screen, the screen went black for a bit, then booted into ubuntu. i only tested this once but im worried my windows is gone.</p><p>pls reply someone.</p><p>thanks.</p>
<p>just checked again and everything is fine.</p>
<p>could you boot mac os as well?</p>
<p>Yes. Mac uses the same architecture as an Intel PC so you'll have to be using a system with an Intel processor. Just search Instructables... I'm sure they have a how to somewhere. =)</p>
<p>can i use ubuntu via USB directly? Or is it mandatory to install Ubuntu on my pc??</p>
<p>Some linux dist allowes LIVE version of the OS, but i recommend installing it to the hard drive and dual boot </p>
<p>Upon bootup, you will now see a choice between Windows and Ubuntu Linux.</p><div> I dont see this!<br></div>
<p>While booting go to the bios and choose, it can be accessed by pressing F10 in most pcs.</p>
<p>Only 10 steps? I am sure, you can make 100 easily!</p>
<p> Good job pal...I did it many times in the past and everything went well for simple use. The troubles are when you need something &quot;more&quot; from your PC. This solution is excellent when you want an OS to surf the internet more secure because of Virus absence or at least minor presence Congrats for your efforts to build a white paper for the masses!!!!! Best regards from Greece</p>
<p>Hi,</p><p>I used the USB option and even after putting USB up in the order in BIOS I am getting Missing Operating System error. Can someone help? </p>
Really helpful. Thanks<br><br>Also visit www.freep360.com
<p>Really a helpful article I've found.</p><p>Oh, I've also an updated version here: http://www.howtouselinux.net/dual-boot-linux/</p>
<p>The first was installed UBUNTU 15.10, now I want to install windows afterwards as dualboot can help a friend?</p>
<p>I just got a product key from <a href="http://www.vinhugo.com" rel="nofollow"> www.vinhugo.com</a>. it worked perfectly. I'm so excited to share my experience here.their customer service is 1st class and I will definitely be recommending the site and I will be using the site again.</p>
<p>lol</p>
<p>Another method During Installation :</p><p>(tested my self) it worked for me</p><p>http://mineconsensus.blogspot.com/p/blog-page.html</p>

<p>i followed the instructions but now i am left only with ubuntu, step 9 is not taking place(i.e. i am not having any option, automatically ubuntu starts) please help...</p>
<p>Same happened with me, then i tried this tutorial <a href="http://www.searchithow.com/2015/02/how-to-install-ubuntu-dual-boot.html" rel="nofollow">http://www.searchithow.com/2015/02/how-to-install-...</a></p><p>Worked like a charm :)</p>
<p>Sorry for the link.. Here is the updated link : http://www.syjj.in/2015/02/how-to-install-ubuntu-dual-boot.html</p>
<p>Greetings you intelligent lot ! </p><p>Although I am somewhat advanced Win OS user I am and utter and complete rookie in LINUX-UNIX domain so I apologize in front for my pretty basic question(s) . I'm attempting to set up Win7 and LINUX dual consoles and while the size on HDD isn't an issue - the speed of future perfomance is. I need it ( LINUX console ) to be fast and friendly in terms of allowing the antiviral/firewall and IP - cloak's to function - in full extent. So my first question is ; '' Which LINUX console version would be the best ( since I can see there are literally hundred's of different Lite and 'Heavy' console versions ) installation for this concept. Thank you for sharing your knowledge with me and the rest of the world - in forward. Ok, that's it for (my) beggining - thinking - I have to start somewhere and this seem' s to be a good place for this, new learning phase.</p>

I have no idea what one you should use but I think CentOS minimal install might be what you're looking for.</p><p>Also: Anti-viruses do exists for linux, I think more exist for the RedHat family of OS's has the most options but all should have at least one. firewalls, if by firewalls you mean simply blocking traffic. You may actually find them unnecessary. are pre-installed but usually disabled in all linux distros. Look for tutorials for &quot;iptables&quot;. Most of all have patience. Its difficult but fun.</p>
<p>Please make your tutorial a little clear as i lost all partitions following this tutorial, so i tried </p><p><a href="http://www.searchithow.com/2015/02/how-to-install-ubuntu-dual-boot.html" rel="nofollow">http://www.searchithow.com/2015/02/how-to-install-...</a> and it worked liked a charm (:</p>

<p>I think it is important to mention that you must install older OS first and then install a more recent one, which nowadays is mostly installing Windows 7 first and THEN Linux, I'm not sure with Windows 8.1, I don't own it thus I can't speak for it. If you install Linux last you get the option of which OS you want to run, otherwise you will default your machine to Linux or even worse - won't be able to boot at all.</p>

<p>awesome tutorial.</p>
<p>is this a joke</p>
<p>i followed the instructions but now i am left only with ubuntu, step 9 is not taking place(i.e. i am not having any option, automatically ubuntu starts) please help...</p>
<p>VMWare Player is free for non-commercial use and works for Virtual Machines (it cannot do .iso files)</p>
This is fine as far as it goes, but if you have a reasonably large machine you should look into running ubuntu under windows in a virtual machine. This lets you run both at the same time. One way is to search instructables for &quot;virtual box&quot;. This is an easy process.
Wait till uefi becomes standard. We will really be cut off. The public needs to boycott such machines.
