Dual-boot Windows 7 and Ubuntu 12.04 on a PC with UEFI hardware

I am reading page: 1 2

7. Create Partition Window: This is the partition creation window. With two primary partitions existing on the HDD, the installer will want to create the partition as a logical partition. You can accept it or change it to a primary partition. Knowing that you can only create four primary partitions, creating the boot partition as a primary partition automatically makes any subsequent partition a logical partition.
Create Partition

8. Create Boot Partition: Ok, time to create the boot partition. Notice that I made it a primary partition, allocated 500 MB of disk space to it, and kept the default file system, which is Ext4. OK.
Create Boot Partition

9. Create Root Partition: The root partition is where all programs will be installed. If you do not create a separate /home partition, it is also where your home directory will be located. For this test system, I allocated 100 GB of disk space to it. Use the default file system (Ext4), and set the mount point to /. OK.
Create Root Partition

10. Create Swap Partition: The last partition is for Swap, which I allocated 4 GB of disk space to. From the Use as dropdown menu, select “swap space.” OK.
Create Swap Partition

11. Partitions List: When all the partitions have been created, you should be back to the main Advanced Partitioning Tool window. The final task at this window, before clicking Install Now, is to select where GRUB, the boot loader, will be installed. By default, the installer will want to install it in the MBR, but doing that will overwrite Windows’ boot files. To retain it as the primary boot manager, install GRUB in the boot partition, which is sda3.
Create Swap Partition

12. Device For Boot Loader Installation: So, select sda3 from the Device for boot loader installation dropdown menu. Click Install Now to continue with the rest of the installation. After installation has completed successfully, reboot the computer. It should reboot into Windows.

13. Install EasyBCD With UEFI Support: Once in Windows, the final task is to install an application that will make it easy to add an entry for Ubuntu in Windows’ boot menu. EasyBCD is one that I have always recommended. I am sure there are others, but it is one that I find to be very noob-friendly. For home users, there is a free version that you can download from here. The latest version, EasyBCD 2.2, has support for UEFI hardware. Download and install it as you would any other Windows application. This is the main interface. To add an entry for Ubuntu, you want to be in the Add New Entry tab.
Windows 7 EasyBCD 2.2

14. Add Entry For Ubuntu Using EasyBCD: In this tab, click the Linux/BSD tab, select GRUB 2 from the Type dropdown menu, then customize the Name filed to match. In the Drive menu, the default is shown here. That is what I used, and it worked without a hitch. You can also select the boot partition from the menu. After making the changes, click the Add Entry button. Then click on the Edit Boot Menu tab.

15. Windows Boot Menu Entries: Here you can see the two entries as they will appear whenever you reboot. Quit EasyBCD and reboot the computer.

That is the end. Hope it works for you.

    Hi Finid,

    I have followed your tutorial to the letter trying to install Ubuntu alongside Windows 7 on an Asus laptop having UEFI system and GPT partitioning but when I tried to reboot into Ubuntu I got the same error that I encountered sometime back when tried to install wubi.

    The error:

    Windows failed to start. A recent hardware or software might have caused the error….

    File \NST\AutoNeoGrub0.mbr
    Status 0X0000098

    The selected entry could not be loaded because the application is missing or corrupt.

    I have tried different boot loader types (GRUB 2, GRUB(legacy) etc) when adding Ubuntu on EasyBCD but it still doesn’t work.

    The only thing that I did differently during the installation is that, after creating the three partitions as you have recommended and clicking on ‘install’ the system suggested I go back and make another partition of type ‘Reserved bios boot area’, which I did and allocated 480 MB. I have even tried to book from this partition but it still doesn’t work.

    Could you may be have an idea of what went wrong?

    Thank you!

    Hi finid,

    I have a brief question: is there a specific reason why, except for potential Windows Updating from Win7 to Win8, on all your installation guides you suggest to boot on Windows MBR instead of booting directly on the GRUB manager?

    Does it have something to do with the UEFI or the Intel Rapid Storage Technology (when a small SSD exists)?

    Last year my former computer crashed and I’m pretty sure I used one of your guide to install a dual-boot Win7/Mint Maya booting directly on the GRUB but I cannot see this tutorial anymore. Is it me or did you change the tutorial?

    Thanks!

    • finid says:

      It’s not just upgrading Windows that could scuttle a dual-boot with GRUB in the MBR, but some 3rd party security solutions have been known to mess with the MBR.

      Also, putting GRUB in a boot partition instead of the MBR makes it easy for you if you decide to remove the Linux distribution.

      Btw, all the dual-boot tutorials are up and I did not change anything. Note, however that a few of these UEFI-related tutorials are not actually UEFI, because the system I used was booted in BIOS mode. But that does not apply to your case.

      And I don’t think dual-booting in the manner given in the tutorials will cause a crash.

      Also note that in most cases where a PC is said to have “small SSD,” that SSD is not actually a separate drive, but part of a single device that combines an HDD and a NAND Flash, so-called solid-state hybrid drive (SSHD).

      • reponsatou says:

        Thanks for your reply!

        I get your point. But then, when the PC boots on the Windows MBR what happens when Windows crashes? how can you boot on Linux (without a LiveDVD I mean)?

        (if your tutorials are updated I must have mixed up last year when installing Linux, sorry for mentioning that.)

        Regarding the UEFI, I had Windows 8 pre-installed on my new laptop. I managed to replace it with Windows 7 by deactivating the UEFI mode. So technically I’m not using the UEFI but it’s still there on one of my HDD partition (Gparted can see it) so I don’t exactly know if I should consider tutorials with or without UEFI…

        As for my SSD of 24Gb, it is separated from the HDD.

        • finid says:

          When dual-booting on a single HDD, there’s a risk, whether you use GRUB or Windows loader as the master boot loader. That’s why the best route to go, is to use 2 HDDs, or 1 HDD and 1 SSD, or 2 SSDs.

          If you are booting in BIOS mode on an HDD that came with Windows 8, the GPT data strutures are still on the HDD unless you zapped them. You might want to take a looks at this article.

          Note that UEFI and GPT do not necessarily go hand in hand.

          • reponsatou says:

            Thank you for the link to the article, it is very interesting. I never thought about this GPT issue before. Assuming (I have to check) that Windows 7 has been installed with the GTP table, is a dual-boot with Linux Mint hopeless when keeping the GTP table?

          • finid says:

            IF GPT data structures exist on the HDD before you installed Windows 7, it is very likely that the installation process did not wipe them. That could show up as an issues when installing Mint or any other distribution. If you are not using a GPT partitioning scheme, get try to get rid of any existing evidence of GPT before commencing an installation.

  3. Frederik says:

    I get a choice menu to boot either Win-7 or Ubuntu
    but Win-7 boots fine and Ubuntu does not boot at all.
    When I choose Ubuntu I get to a Grub promt, no further.
    Please help, thanks.

    EasyBSCD reports as follows:

    There are a total of 2 entries listed in the bootloader.

    Default: Windows 7

  4. Craig says:

    Thank you for the tutorial. I followed your instructions to the letter and yet I am presented with a GRUB4DOS screen after choosing to boot from the Ubuntu 12.04 LTS entry created by EasyBCD. The partitions are exactly the same as you’ve set up so I don’t understand. The entry found and added by EasyBCD is Drive C:\ then Bootloader path \NST\AutoNeoGrub0.mbr

  5. delaney says:

    Now, the question is, how to do this with gpt partitioned drives?

  6. Sophia says:

    Hi, could you tell me if this would work with dual booting ubuntu 12.4.2 with windows 8? I get the feeling windows 8 has made it even more difficult.

    I managed to get to the ubuntu installation on my computer but it didn’t detect windows 8 OS and so i’m worried this will be a problem later…so haven’t installed anything yet…

  7. cooldude says:

    i partitioned as described(for me i allocated a 25gb from my E-Drive) 25gb unallocated. Then i loaded ubuntu in pendrive. first time installing ubuntu it shows “unusable 25gb” in ubuntu partition list. so switched to win7 to check partition. it was same wat it was already as 25gb unallocated. now i try ubuntu,this time it showing as “C” as dev3 and “D,E,unallocated space” together as dev4. i cannot find the 25gb as free space how to get it to install ubuntu please help me. Thanks for ur help.

    • finid says:

      If Ubuntu’s installer is seeing the C drive as /dev/sda3, what is in sda1 and sda2?

      That D and E are separate partitions after C (sda3), means that you have exceeded the max number of primary partitions that the partitioning scheme you are using supports. That max number is 4. That’s why E is showing up as “unusable” space. To be able to use it, you have to delete it, assuming that you do not have any data on it. And also no data on D.

      Once you delete both, you can then use the combined space from D and E to install Ubuntu. If all this sounds foreign to you, take a few moments to read guide to disks and disk partitions in Linux.

      Back to the first question. What is in sda1 and sda2?

      • cooldude says:

        used
        sda1 reiserfs 1MB unknown
        sda2 ntfs 104MB unknown
        sda3 ntfs 150GB
        sda4 ntfs 160GB

        • finid says:

          Assuming the first OS on the disk is Windows, how did sda1 with 1MB of disk space end up with a reiserfs file system? That does not look right.

          • cooldude says:

            is there any way to solve it? i still remember last december i formatted my entire hard disk and installed freshly win7. when i google for reiserfs i found its belong to linux. can i delete it and try ubuntu? why i am asking tat because tat 1MB is not listed in win7 disk management.

          • finid says:

            Yes, reiserfs is a Linux file system, and it is not even the default in Ubuntu. So, that 1 MB partition has no useful function there. I thought it was a bios_boot partition, required for GPT partitioning, but that is not supposed to be formatted.

            You could wipe the whole disk and reinstall, if you can afford to. Otherwise, you’d be wasting 1 primary partition.

  8. When I have tried to install in the same fashion, I have received an error

    “No root partion is defined.Please correct this from the partitioning menu.”

    I am not able to understand it, though I have 66Gb free space for ubuntu 12.04.1 installation. Previously this kind of error never comes. Is there any hardware issues or somthing else.

    PC Configuration:
    350Gb HDD
    AMD Phenom(tm)II X4 B97 3.2Ghz Processor
    4GB Ram.

    HELP ME Plzzz.

  9. Bill says:

    Thanks for the tutorial. It’s a great basic guide to the installation of a dual-boot.

    Most people run into problems with a UEFI system, though, possibly because of an issue that wasn’t mentioned in the article: you’ll need to get the Ubuntu 12.04 64-bit edition, and choose the UEFI option when booting from the live CD.

    I can’t personally vouch that this solution works yet, since it’s late and I’m going to try it tomorrow and let you know how it goes.

    This is the link to the explanation: http://www.linuxbsdos.com/2011/09/18/guide-to-disks-and-disk-partitions-in-linux/

    Hope that helps.

  10. Dirceu says:

    Does the boot partition need to be of a primary type?
    I tried the installation procedure on my Sony laptop. There are MANY partitions for laptop recovery, and other purposes. When I tried to create the first Linux partition, the boot one, it game me no option to create it as a primary one. I went ahead with the other partitions, and directed GRUB2 to be installed at /boot partition. In the middle of the installation, program reported an error – not able to install into the /boot partition, asked me to select another one. Obviously, I selected to abort the installation…
    Any clue how to get out of this problem?

    • Dirceu says:

      Sorry about replying to my own msg – more information: I went back to my win7 disk manager, and there I can see the boot, root, and swap partitions all reported as primary partitions, as follows: 477MB primary (boot); 111.76GB primary (root), and 3.73GB primary (swap).
      The interesting thing is that all 4 win7 partitions, as well as 3 linux partitions, are reported as primary. I thought there could exist only up to 4 primary partitions…
      Comments?

      • Dirceu says:

        One more piece of information: I went back to Linux installation partition tool, and the volumes shown are not cleanly named as /dev/sda3 (for boot partition), but rather:
        /dev/mapper/isw_cagijcdieh_Volume0p6 (ext4)

        I also noted that the tool no longer show any mount point…

        • finid says:

          Hmm, /dev/mapper in Ubuntu 12.04. What edition are you attempting to install?

          And what is the size of the HDD, the size of the Windows partitions.

          • Dirceu says:

            12.04 amd 64bit edition. My laptop has a win7 64bit installed. HDD SSD 512GB. I have shrunk win7 C drive to make room for 120GB unallocated space…
            What does /dev/mapper mean? I confess I did not like it when I saw that…

          • Dirceu says:

            OK, my problem is that I have a RAID as HD. I guess I need the alternate iso version…
            You would not have a version of this tutorial for RAID disks, would you?

          • Dirceu says:

            I guess the differences in installation are in the disk partitioning/creation of the /boot, / and swap areas.
            In “alternate installer land”, after “Detect disks” step, when I select “Activate Serial ATA RAID”, I get the following as the reading of my ATA RAID device:
            Serial ATA RAID isw_cagijcdieh_Volume0 (stripe) – 512.1 GB Linux device-mapper
            #1 primary 22.1 GB ntfs
            #2 primary 367.0 MB B ntfs
            #3 primary 355.2 GB ntfs
            logical 125.8 GB FREE SPACE
            #5 logical 8.6 GB

            So, I assume linux device mapper is able to coherently read my ATA RAID disks. Shall I then just select free space, and start adding partitions just as in the tutorial?

            Anyone has done that before?

          • Dirceu says:

            Quick update. I was able to create /boot, / root and swap partitions using alternate installer on my RAID0. However, installer reported a “Installation step failed” under “Select and install software”. It then offers the option to continue…but I decided to abort the installation.
            Does anyone know whether it is safe to skip “Select and install software” step, and proceed with the installation?
            I also headr that during “GRUB installation” step, one is not offered the choice of NOT installing in the MBR of Win7 by the alternate installer…Can anyone confirm this?
            THanks

          • finid says:

            Not a good idea to skip steps. When you start doing that, it’s likely to skip more steps and you end up with a system that fails not boot.

            I’m not sure of that last question about GRUB, but that should not be a problem. After installation, you can always change GRUB’s location.

          • Dirceu says:

            I went after system messages during alternate installation. There are many error messages, and most of them related to “not finding” a particular folder supposed to be mounted in the RAID0.

            So, I am bailing out. Will try next to run Ubuntu inside a VM on that machine, with all potential limitations.

            Thanks

          • dirceu says:

            Last update. After using alternate installer disk partition on the Vaio machine, I tried to expand back Win7, and FAILED.
            I had to reimage the OS back to factory condition, or else I wuld have wasted over 100GB of SSD HD – not good.
            So, dont try this – wait until Ubuntu installer is able to deal with Intel Fake RAID used in latest Vaio machines.

      • finid says:

        If you are seeing more than 4 primary partitions, then the partitioning scheme is GPT-based. See this article for more on that subject.

  11. Mint says:

    It is my understanding that UEFI dual boots can only work with 64-bit versions of Ubuntu. I tried 64-bit Mint with no luck. I’m now going to try again with Ubuntu 12.04 64-bit and see how it goes.

    If 64-bit is required, I recommend you clarify that early in the tutorial.

    • finid says:

      Well, I trying to dual-boot 64-bit Windows 8 Pro and Ubuntu 12.10 64-bit on UEFI hardware with no luck – yet. Windows 7 and Ubuntu works, a you can see from the tutorial.

  12. Mint says:

    I followed this tutorial and received the following error when trying to boot into Linux Mint…

    “Windows failed to start
    … [text here] …
    File: \NST\AutoNEOGubo.mbr
    Status: 0xc0000098
    Info: [more text here]

    Does anyone have any idea how I can get back on the tracks?

    TIA…

    • finid says:

      What’s the setting on your UEFI setup utility, and could you post your drive partitions here again, where the /boot partitions starts.

      Curious thing with these errors being reported is they’ve never happened in any of my test installations.

      • finid says:

        Give the whole specs on your HDD and mobo. If it matches mine, I’ll try and reproduce the error. If I wasn’t having major problems with my migration, I’d post a separate article for dual-booting Mint on UEFI hardware.

        • Mint says:

          Hi finid, I have an HP P6-2120 desktop computer. It has a 1TB drive.

          SDA1 Win7
          SDA2 Win7
          SDA3 Win7
          SDA4 (Nothing here)
          SDA5 /Boot
          SDA6 /
          SDA7 /Home
          SDA8 Swap

          My current approach is to turn off UEFI completely and install Mint in BIOS mode. I have a question, though. If I do that, do I need to set aside 1 MB for the Reserved BIOS boot area or is that something I should skip? I think I skipped it before and the BIOS didn’t recognize any OS to boot.

          I’m afraid to try it for fear it might mess up the Win7 bootloader – even with UEFI turned off.

          TIA…

        • Mint says:

          finid, it just dawned on me that I didn’t follow your tutorial to the “T”. I partitioned with Miint Live CD – and that might be why it didn’t work right. I will undo my Linux partitions, expand the Win7 partition and then follow your tutorial to “T”. I’ll let you know how it goes.

          • Mint says:

            finid, I’m currently going through the tutorial and I wasn’t able to simply restart and go straight to the LiveCD.

            For people with a similar situation, a note that some systems might have to disable UEFI in order to boot into a LiveCD would be helpful.

            There is no way that I’ve found that will let me boot into a Mint LiveCD without disabling UEFI – and that includes listing my CD/DVD as the first UEFI boot choice.

            I’m going to download and burn the latest Ubuntu and try to boot with that instead. Maybe Mint is lacking the ability to boot UEFI whereas Ubuntu’s latest might have that ability.

          • finid says:

            I never had to disable UEFI for this tutorial. I’ll write something for Mint 13 soon.

          • Mint says:

            My attempt with Ubuntu 12.10 failed in similar fashion as well.

            I’m wondering if the HP Pavilion H/W and Boot Loader config is to blame.

            I’m at a complete loss as how to proceed.

            There was a warning about a Reserved BIOS boot area being required, but I didn’t it mentioned in the tutorial and I didn’t go that route for fear of possible damage to the Win7 boot loader.

    • Steve says:

      Hi Finid,

      Thanks for posting these tutorials.

      I got the same error message as “Mint” did (Windows failed to start…AutoNeoGrub0 etc.) after following this tutorial. Got the same one when I first mistakenly followed your BIOS tutorial not realizing what UEFI was.

      Trying to dual boot onto an Asus U47VC-DS51 notebook with 750gb.

      Does this mean that Mint cannot be dual booted with my machine? Will I have better luck with Ubuntu?

      Thanks,
      Steve

  13. phalloc says:

    great very simple tutorial, i bought a new computer a week ago, and didn’t new about the EFI technology, i ended messing everything up by not booting in UEFI mode, but then i learned how to do it and folowing this step by step all worked out.
    thanks!

    EasyBCD is not under an open source license and requires a paid license for commercial use.

    But don’t despair there are several other options here.

    One is to use grub as the bootloader.

    Another is rEFInd http://www.rodsbooks.com/refind/installing.html

    Another is to use the efi kernel stub and the firmware included boot menu.

    • finid says:

      What is wrong with requiring “a paid license for commercial use”?

      If you are using the software in a business environment, don’t you think the developer needs to make money, too?
